Hi gr5, thank you for your fast reply. I used the same settings as 2 weeks before, when I started to use the new filament... so this can hardly affect the delay. As well I normally see the cores heating up again (red flashing light)... this doesn´t happen. It stays white while pending at the nozzle switch station... I seems to me that there is a mem-error or some kind of loop that needs to be broken prior to continuing to print... as well in the beginning there wasn´t hardly any delay. As the printed object got hiher in the z-axis the delay started to get more immanent. Maybe it recalculated the sliced objekt again each time when it hoped to another z-level and then trying to refind its position.. I will try to print another object when I come back from my x-mas trip in a week and then hopefully the error will have "magically" disapeard into some paralell universe ;O). Have a good christmas-time with family or friends! Greetings Daniel

Hi to all of you... I have obtained a new problem which I never had before and it showed only 2 days ago... 1. I have a new setting since 2 weeks as I am printing parts with CF-20 filament with an apropriate nozzle... 2. This in conjunction with the normal BB 0.4 of Ultimaker The prints were all fine until yesterday I experienced some "underextrution" issues on one side of my prints. Now the print seems to be fine, but at the layer change the printer decides to make a brake of 20 seconds each time befor starting a new cycle. This costs time and cools out any layer it has made previously... I have never experienced such a "delay" and it seems the higher the object gets, the more "thinking time" the printer needs. Would the slicing be corrupted? Or the g-code? Maybe one of you has had a similar problem Greetings to all crazy-one out there still printing on x-mas time... Daniel

Hi Smithy, Hi JohninOttawa, I really did run in some problems. But theese problems were DOS based problems. I did forget that the codes will not accept the "new" long path´s entries which are longer then 6 characters and no special characters as well (see short DOS-path (8.3) ... so I had to rechange the path to a "simple" one and it worked. Now I will try it... See you around. I will mark this as "Problem solved now" Greetings Daniel

Hi Smithy, thank you so much... I´ll change it a bit later and try it on my next bigger printout. I´ll let you know it it worked.. Breakfast in Austria= Great! Need to visit some place there again soon (probbably for skiing purpouses).. but I miss your local food! Greetings from Heidelberg Daniel PS: I have added a little something I just did the day before yesterday as a present. Maybe it is worth some use... I have tried it and it works great for me. Feel free to add, adapt or change anything you like... The holes I leave it up to you to drill or draw in later as the frequency can be adapted (Not everybody wants to start with a C..)

Hi to all 3D-Print addicted (like me). Cold weather and the dark season thrives me back into my home wanting to create new stuff. Sometimes something goes wrong (not that you know of those problems ;O) ) but for me one thing that helps me is my built in camera of the UM3. I use one of the scripts I found here in the community. It is written in python and it works great (Timelapse.py). There is just one trouble with it and I can not find a way of changing the dumping folder in the program itself. Right now it uses the "temp"-Folder of my PC in order to sequentially save a foto there. Then when the print is over, the program takes those fotos and combines them together to an .mp4-File that can be watched. In the past and when i was printing things this was a good way to see the print in a few seconds and say "Yes, that was good" or at some point "sc.. what happened"... this way sometimes I could figure out the problem just by looking at the condensed film. Now as I come out more often to print jobs that take more time (1 day and more) the problem starts. The "temp"-Folder of my PC emptys itself out every time 24h have past and this effects the dumped pictures as well. In the beginning I thought I was doing something wrong but actually the program needs a continuity in order to combine the fotos to the vid. Once the PC has erased one day of fotos the next fotos are continuing with for example tx000130 and not with tx000001. Combining them will not work anymore and the program crashes every time this happens and leaves me only with the fotos of the last day... First try to find out how to avoid the automatic erase of the "temp"-Folder was not successfull... anyhow the Software would not have to installed such a folder if it wasn´t for a good reason. Therefore in the next step I tried to find if the "temp"-Folder would be written in the python-program as a path. But this as well was not the case. And to interpret the language I am not into python-programming too much as to say that I would want to change anything in there. Therefore my question: Maybe one of you is good in programming with python and can reprogram the saving-folder to a different place (any place that is not erased automatically after a certain time and not the desktop would help). I will leave you with the program itself so that you may use and reprogram it as you wish. Thank you for any help regarding this problem. Greetings Daniel PS: please try not to "unzip" the file. I just changed .py to .zip in order to beeing able to attach it here ;O) timelapse.zip

Hi Brulti, Hi kmanstudios, yep probably that was it... I didn´t pay attention when I opened the box.. but nontheless the box was covered with the UPS box, so if I open it, that means goodbye for the money cause I lack the proove that it was defective the first place. Well it was the first time for me and I hope that will not happen too often... as this would result in a russian roulette kind of buy. Anyhow now I posess 2 BB´s and I will try to reuse the first one. So if it works that save me the second until the first dies for good! See you around!

Hi Brulti, simple answer: it was the filament! I don´t really know why, but it was the filament... I didn´t use it too seldom and it also was "only" a half-spool. Did I mention that it was the filament? Well I am happy now that it wasn´t some tricky bug in Cura or even worse, in the printer itself. So I hail to all persons who have supported me with their ideas on how I can go ahead. Here is a final pic from the print. I´ll clean it tomorrow, because now it´s just too late to do that. I also took a timelapse of the print but the bastard of my PC killed 90% of all pics in the temp-file and thus the program ffmpeg wouldn´t find nothing anymore to compile. Such a s... (btw. that was my 1st 2.5 day-Print) ? See you around Daniel PS: It was the filament! Strange, but true...

Hi Brulti, thank you again for your answer! Unless I get another filament that could withstand those temperature I also will forget about the ease of letting it get washed by my dishwasher (unless I hated the part anyhow)... Now to the bad part: It failed again even with the new printcore. Now in this case I have one last thing to change --> the filament ! I will do that on Sunday. Then I will try it again and see what happens. If that failes again I am out of ideas... I will report on Monday or Tuesday next week... Greetings Daniel

Hi zaqi, nice to hear of you again. So here is what I did. Seeing that you have installed the programms alright it will be only a matter of getting the syntax right.. I now took a screenshot the actual program and made some detailed explanations on how you use the different syntaxes and where they are placed and what exactly they do. If you get it right the programm should wait for you to start the printer and then start taking pictures... I tried everything from each time 1 pic every 30 seconds to 150 secs and they were all good. Only the last numbers only make sense if you got a large print and you want to see it fast in the end. If you want so see where something went wrong it is advised to use smaller numbers e.g. 30-50. Then you see more detail in the building but it will take more time. Hope you will get a success this time. Greetings Daniel

Hi Brulti, just like you said... it wasn´t the best idea.. nonetheless it worked on a couple of month. Now like I said I bought the original BB "again" and I will treat it like a princess hoping that it´ll last me a little longer. Only after this one will leave me as well I will try the Solex. Until that time I will try to optimise my knowledge with cura... I will let you know it it ultimately was the hotend or not... Greetings Daniel Btw: Do you know a filament that will not be destroyed in my dishwasher? Lat time I printed a coupling between a big BBQ-Bottle and a handpump. I worked great until I decided that it would be time to give it a wash. I used PC and in the sheet it sais it´ll be stable until 110 c°. My dishwasher uses 90 c°. When it came out clean, it was too much distorted, so I had to print a second one...

Hi Brulti, I think you are right! I ordered a new core 2 days ago and I will get it on Monday. So I will let you know. I think the core was eaten up... I once cleaned the outside of the nozzle with sand paper and I scraped off too much so I kind of redid the nozzle-tip with a sandpaper of a smaller granulat and it kept working... but 1 month ago it was clogged too much so I decided to open the hotend and it was all burned up inside (I couldn´t even to a cold pull anymore). So I decided to drill it free with a dremel and a drill of the same size... it came free alright and it worked again, but I think now I changed somehow the incline of the inside of the nozzle itself. Yesterday I had to free it the same way and after reinstalling the tip in the hotend, I reallized that the filament flew free, but i got harder each minute to press it throuh so that the filament would flow out the same amount. I suppose that´s what happened now to the filament each time I try to print... at least that is my last guess, too. I hope the new core does last a little longer though. I plan on buying one of the cores with changable tips (solex). Do you have any idea if that works better because spending 120 euros everytime that BB or AA core is clogged too much will destroy my pocketmoney for other things... ;O) and the other nozzles come in different sizes, too. I will let you know once the new BB-Core is installed if it workes better now... Greetings Daniel

Hi Brulti, that is what I thought, too... until the day bevore yesterday. I was all cleaned... but still the problem persists... Not i´ll try a higher print temp and a slower print velocity. maybe that helps... Maybe the printhead is somewhat "worn off" it is always so dirty after a print. If you have any other clues you got the g-code, so you know what type of setting I use.. besides that I changed the "adaptive layer" away. I will try it again this evening. Greetings to all of you Daniel

Hey Dim3nsioneer and DF-Werkzeugservice, I just started another print and (cross my fingers) thus and up until now, it worked fine (withot a starting problem printing PVA correctly in the middle of the printout (it got partly ripped away). But after a few layers it had stabilized again... so far so good. I can only tell you, after the print is finished. I will take another Day and a half for it to finish and if it finisheds I have a smoth solution to place my pad in my car! So far to say I can say 2 things: 1. The feeder-roll was taped with PVA-powder, so I thouroughly cleaned it today (solving 1 problem I hope). 2. The bigger problem probably was that I used an experimental adjustment, that probably will not go good with PVA. I was the "adaptive layer" one. I was trying to save me 1 day... Now it´s printing it regularly layerwise and everything seems to work out just fine. Tell you tomorrow, if I´still happy... See you Daniel

Hi Dim3nsioneer, thank you for your reply... 1. The PVA might have picked up humidity. Is it sizzling during extrusion? NO... it extrudes normally 2. I opened the feeder completely the last time but this print failed completely as you can see in the attachment (zipped File).. BUT, I recognized the day that I made this print that the feeder did not advance the filament enough for it to print out the first "blob" before going to printing the brim... so I helped the filament very fast with unlocking the feeder suspensiton and pushing in the filament manually.. then it worked. So it should be an issue with the feeder I suppose. I will look in it again and send you in some fotos. Can it be that the feeder "didn´t get the info" sometimes from the hardware to advance and retract? Always when I have this problem the filament inside the tube looks a little pushed but if I push it with my hands manually the flow is restored after a while and it runs normally so the pressure shouldn´t be a problem but the feeding... I will send in some fotos later that day. Greetings Daniel

Got it... problem not solved but it seemed to be evidend all the time. Thank you!

Hi Zaqi, Sorry for the late repy. I can try to help you... First of all --> forget about the "request"-problem. That was my 1 attempt to get the programm running. You should first download the python-program in the right version for your PC (32-bit, or 64-bit). Then you install this and take the python.exe program to your desktop (with drag & drop if you wish). Then you have to download the timelapse.py file and put it on your desktop as well. Now you have both files on the desktop. GREAT! So far so good... This is now where you start the CMD (command line shell) in your search box (it is located in the lower left section where the start button of the windows is located as well... you will see it. It is a small command line with a loupe next to it. There you write inside cmd. And after you press start a black window will open and you will see a promt line, like "C:USERS\Administrator\" there you have to add the command: "cd desktop" (withouth the "). This will lead you to the desktop where the 2 programms are sitting. There you can now activate the timelapse like I described in step 8 and following... then you have to start the print and the program will recognize that and will stard taking pictures every X seconds that you have told it to take one. In the end the program tells the PC to combine those single frame fotos to convert them into one .mp4-File. There is where you will pic it up and enjoy the print in timelapse. If you have further questions let me know Greetings Daniel

Hello to all of you! Nowadays I encounter a problem I haven´t had so far. Recently I printed 2 prints with natural CPE with a support of PVA. Unfortunately in both prints the PVA suddenly stops extruding. After a thorough cleaning of the nozzle, the Feeder and the filament rests surrounding the nozzles outer rim, I retried the print.. the first one "survived" because the important support survived the nozzle print-time before the filament extrusion came to a full stop. The second print requires 100% support but I can not seem to detect the problem. The outcome is always the same. After 5-6 mins. the extrusion goes from perfect to low quality and the eventually stops. Filament is then grinded and stuck in the BB-Core. After heating the Core to 240 degrees. I can manage to manually deblock the nozzle, by pushing the filament into the nozzle by my hands. The first seconds are hard then the filament extrudes ok and the nozzle works again (like I said for 5-6 minutes)... What in h.. is wrong? I haven´t changed a lot since my last prints. But even if I did I never had that result. I tried on default system entries and on custom. Both seem to show the same problem. Could it bee a general problem with the core? I use it already for 1 year although I do not print regularly. The last print was 3 month ago... I will leave you with a timlapse of the video. I took it too late but you will see what I meen once you will see the print... Hope you have some ideas what is wrong with the nozzle (or the feeder). See you Daniel PS: the converted mp4-File to .gif didn´t load up either (what a stupid day)... so now I zipped it for you to see it (if you want to download it and unzipp it...) ;O) gl450halterung.zip

Hi there, I use the UM3ext. for 6 month now and I am quite satisfied with the prints. Now I tried to print a cover that I drew on Mechanical in "PC" in conjunction to "PVA"... bad thing! I now know that this is a no go and that it will not stick together. Anyhow in order to beeing able to process a 3D-Type Object that is starting on different hights (Z-axis) I wonder what I could use instead. Does anyone ever tried to use another filament (for examble TPU as a support instead of the PVA that is producing nonsense results? If nothing is working, does Cura have an app that would calculate a removable support that I could add instead of the PVA? Maybe some of you did encounter some similar problems before... I will leave you with a picture of the object I want to print... would be great if you would have a solution to that, because the PC will be washable in dishwashers, too without turning into indifferential ART... Greetings and a nice upcomming weekend to all of you! Daniel Deckel Saft City 2.stl

Hi gr5, thank you for your reply. I will check the "belt issue" for sure! I am using a UM3 Exd. and as I am already printing for some 6 month+ I supposed it was not a hardware-based problem. Nor was there a problem with overhangs. The main problems was that the objects did come out in another shape than Cura slices them (see comparison of the black objects) Another problem was that the objects printed were not perfectly round anymore (see the "ripped off" curve from the syringe and the stamp... Right now this issue seems to be solved. I tell you what I did. First I reinstalled CURA because there was an update beween the last and the acutal print. Every time I checked the slice-view and there was no difference in beween the print-views. But as you saw the black parts came out way differently, so I suppose it was Cura itself. Anyhow I completely reseted Cura and also the UM3. For now it seems to work fine again. Maybe there was still another issue with the PVA-layers in conjunciton with the overhangs because the overhangs I usually print with support every time. When the nozzle with th PVA behaves strange (what kind of happens sometimes if the nozzle is not 100% clean) it tends to string and probably that is what left the traces on the ball. Another thing I recognized is that with the experimental check "use adaptive layers" I can not print in conjunction with PVA. This will fail 90% of all times so I quit using this. Sometimes this will save alot of time but it won´t work in conjunction with PVA nor does it work with the PVA alone. This cloggs and rips off the material everytime and no overhangs will survive after that. Anyhow I will do some research on the belt issue but I hope that it will not happen again and that it was a Cura - realted issue ( I´using Cura 3.2.1 right now b.t.w). Greetings Daniel

Hi, I am printing objects now for a couple of month and have advanced quite a bit. First I used sketchup then I trained on spark mechanical. Now it´s running fine but since the update of the firmware of Cura and or the new upgrade of the printer there seems to be a bug and I can not see where the problem is. Some prints are not affected. But especcially when I am printing in conjunciton with PVA the objects get distorted or somewhat unpricise (see fotos). Can I do a firmware reset, or can I reset Cura to original settings and retry? Or maybe you know what this is all about and give me some hints in what can cause this. Especially the foto with the comparison print (strange print next to normal print). There you will see a humongous difference on how the same .stl file was and is printed... I did not draw or see in the .stl - File that theere should be a difference between the outer wall and the 4 feet that rise upwards... it should have come out like in the first print. Maybe my printer uses up all of my Gin... do printers can get drunken lately ;O) I am somewhat clueless. Maybe one of you had similar problems and found a solution or has a hint for me as to where I should look for. Greetings Daniel

Finally did it!. Video is ready... FANTASTIC! Wasn´t a clean print sry but my first with 0,1 and probably I have to adapt some ventilation with PVA as for 0,15 there is no stringing... Unfortunately I can not upload .mp4 files so I leave you with some fotos from the compressed single fotos that timelapsy.py took... 1 at the start 1 middle and 1 last foto. Then I took a real foto from the finished print... Hope you enjoy. Greetings Daniel

So to all out there who download Python and ffmpeg and still have problems: 1. Make sure that you have downloaded the right version of Python (there are different versions for 32-bit and 64-bit Systems available). 2. After the installation don´t confuse the syntax for starting programs in Unix-based OS´s with those of WIndows... there are huge differences in installing and running the applications. 3. First put the folder of ffmpeg (not zipped) in a path where it is easy to find e.g "c:\ffmpeg\" 4. Then tell the PC how to find it there... there is a link which helped me to do so: https://de.wikihow.com/FFmpeg-unter-Windows-installieren it is written in German, but you will be able to find out by the fotos attacht to the explanations... in fact I did not have to read them either. 5. The most important information (at least that was for me): If you start python you will not be able to run the script in the shell itself. I mean you can tell the interpreter IDLE to open, or run it but eventually it won´t work because: A) For me the package "requests" was not installed, so you have to install this first... as long as you haven´t done that Python will stop there giving you out a line where it sais something like line 4 "request" is not a known package... B) If you have managed to get Python to know "requests" then you will still not be able to run it over IDLE because it will start the script without telling it the 3 magic informations (HOST, DELAY and name"OUTPUTFILE".mp4). 6. So in order to do so you have to start the script with the CMD-Program (Command Program) of Windows. Open this program and go exactly (where no one els has ever boldly dared to go before) to the folder of the timelapse.py script. For me that was "C:\Users\Administrator\Desktop\." 7. I order to go there please review the syntax of the CMD-Program --> "cd", "md", "rd", "dir" (you´ll manage all with "CD" and "DIR") 8. If you are where your script is. then use the following parameters in order to start the timelapse-process: python timelapse.py Host (for me that was 192.168.1.3 Delay (for me i tried out 10 first then I can try and go higher to save time or lower to go more detail) and Output file (I tried Danni.mp4 to keep things simple the first time). 9. If it does not find Python in order to start the script you might have to tell the computer where to find it. For this reason please use this link: https://www.pythoncentral.io/add-python-to-path-python-is-not-recognized-as-an-internal-or-external-command/ but for me this was OK, and the PC did find it after the installation directly... 9. Then it should work fine and wait for you to start the printing process. 10. Make sure you have Cura loaded and settings ready for printing as I don´t know if it will work elsewise. I suppose not as Cura establishes the connection between the printer and the program... Anyhow these steps worked for me and my first print is timelapesd just now. I am quite happy to have found out by myself and so can you. So happy timelapsing and pls do post some timelapses once you have suceeded. Happy printing Daniel timelapse.py HOST DELAY OUTFILE

Hey to all who read this... Problem is solved! I try to post how as probably som others want to know how and what the problem was about... Greetings Daniel

Hi gr5, yes that is what I am finding out just now.. It is kind of tricky for me in the beginning to set my "Vieving area" every time I want to modify my drawing... then it hops to 2D and I get only the view in that area. What is very need it the "follow"-Tool so you can multiply things around a curve or a plane. I haven´t discovered much jet, but I´ll get there. Another thing wihich I wished I have had in Sketchup is the angle-tool so you can draw at EXACT angles. Great. Unfortunately I don´t get why I would not succeed in copy/paste of for example a circle to another place. I will just not do it. But that is worth looking at once again. Because this will save me time drawing things that repeat (lines, circles) without having to remeasure them again and again and again... Right now I am just playing around with the software until I get ideas... anyhow with the possiblity to create "screws" that really is another world. A couple of days ago I finished my box and it´s working only the sticks I printed in nylon came out to thick and I hat to correct that manually... I leave you with some impressions... Greetings Daniel

Hey unlimitedbacon, I tried your timelapse script but probably I am forgetting something... First of all if I open the script with th editor "IDLE". But this is only possible in the folder I downloaded it to. I tried to copy the files to the Cura folder in order for Python to find the "request"-module over there but there IDLE would not even open the file (don´t know why). Anyhow, I Installed Python and got the ffmpec codec like it was said. Then I tried to execute the ffmpeg.exe but it opened ony a tiny window for a 10*10^-4th of a second.. So there was no visible result! Then I installed Python which went ok. I then downloaded the script. Trying to start it from there would bring me the same result as trying to start ffmpg.exe After looking at the IDLE-Programm I found out that I could also run the script from there but I would give me the following message:"no module named ´requests´". (I added a foto for you to see what the programm would say.) I even tried to start it using your prompt from the Total Commander and CMD, but that had the same effect like trying to start the ffmpg-File. I tried something like "timelapse.py 192.168.1.3 10 Daniel.mp4" (more ore less what you asked for in the beginning of the threat... Anyhow. Probably I am missing out something really simple or probably I have to modify the script... I am out of ideas maybe to can help me in some way.. Greetings Daniel
