  1. Hi - I am having PVA issues as well. Bough a spool a while back and never got it right. Decided to give it a go again so dried it for 18 hours in a filament dryer at 50C. When printing it sounds bacon in a frying pan and seems to be all over the place. Especially when the second extruder is nearing the end of it's layer print and the PVA extruder starts heating up. I find PVA oozing out even though the PLA core is still printing. Attached some pics, not sure whether this is what it should look like. it keeps messing PVA all over the print. I am using the standard PVA profile in Cura but have dropped the temperature now by 5C mid print, will see how that goes. IMG_2880.MOV.zip
  2. Thanks for confirming @Dustin. It has been working well for a while now.
  3. Hi @gr5 With regards to auto levelling; I had this issue from the day I received the printer, so with 76 hours on the fan. I did reach out to Official support at the time and went through a whole bunch of tests, including disconnecting the front fan when levelling. Nothing ever solved the issue and I made peace with the fact. Miraculously, after about a year, my auto level problem disappeared as it never existed. Nothing hardware related was changed, only numerous firmware updates during that time. who know what the problem was on my side, but I can only deduce it was firmware related. Regards, Friedl
  4. @gr5 Thank you for the tips , I will look into this for sure!!
  5. @mrender Oh how I do wish this was the case 🙂 My Cura logs out quite frequently actually... so it was the very fist thing I check. But then on the printer itself under settings it shows that it is not able to connect to Digital Factory.
  6. Hi Dustin - Thank you for your feedback. I was made aware of this fact yes. I'll be honest, if you buy a premium brand printer at a premium price, I cannot see why the warranty should not be honoured. Unless it works differently in Europe of course, but in South Africa a warranty is determined by time from date of purchase, not by who owns it at the time of failure. Further to this, I would image than when an item with only 76 hours on presenting a know issues and well documented problem, their might be some exception to this rule, but alas... it seems not to be the case. So let's agree to disagree on this... I am not sure what you mean, are you saying I will not get support from UM? I am not sure anybody was mentioning WiFi signal strength and quality. I mentioned that this problem persists even when connected via cable. This is the third time this year that this issue presented itself. No amount of power cycling works, not does connecting it via LAN cable. I simply have no choice but the follow the procedure I mentioned above. Please know what may come across and anger towards UM for my experience is mostly due to disappointment in a brand I used to trust in so much. For the first time ever I find myself considering alternative printers as apposed to upgrading. Should have stuck with my S2 printers to be honest. This was quite some time ago, unfortunately I do not have this information anymore. What transpired was UM initially letting me know they will replace the entire print head via the local agents, but then realised I bought it with 76 hours on from someone else and then withdrew the offer. Since then I have made peace with the fact the auto bed levelling will most likely fail at least once or twice before every print and that I will run into these network problems from time to time. Seems all the things I bought the printer for are the things that are now causing issues. Thankfully dual core printing seems to work. Regards, Friedl.
  7. Hi Smithy - Thanks! Unfortunately I am not sure they will assist as I am not, as that they refer to as, 'the first owner' of the printer. I bought it with 70 hours on the machine and has had bed levelling issues since day one. Then also they said they could not assist due to the fact that I bought it from someone even though it was in warrantee still. The way I "fix" it is by Resetting the printer to factory settings. I then have to connect via cable and download the latest stable firmware. From here I reset Digital factory and only after completing these steps the "connect to digital factory" button comes to life and I can add the printer again. Annoying indeed. Thank you for letting me know the S5 has the same issue. I was looking into upgrading again and since the S7 is out of my reach, I was considering getting an S5. Maybe not then... Regards, Friedl.
  8. Hi - I was wondering whether anybody is experiencing the problem where the printer would lose connection to Digital factory permanently. In network settings I have an IP address, but the "connect to digital factory" button is greyed out and a message is indicating that I require a network connection. Going back to network settings I can clearly see the IP address. Further to this, the WiFi icon on the printer clearly indicates it is connected. I have also tried connecting to LAN cable directly, but the same problem persists. @Smithy Any ideas? Regards, Friedl
  9. I think I found my mistake.... You should select the Generic version of the material and then click on DUPLICATE... Which then begs the questions.... what is the BIG BRIGHT SHINY "Create New" button for? 🤷‍♂️
  10. Hi Smithy - I have been using Fillamentum en Fiberlogy for years now. For some reason now all of a sudden it is presenting this issue. I recall when I first made custom materials this error presented when the material type was not selected. In this case, the procedure I followed in an attempt to fix this was; Deleted custom config folder and restart CURA Select Generic PLA material and click on create new Adjust name, color and print temp settings and leave type (PLA in this case) in tact. When printing, I select the material for each extruder. Upon printing this error pops up and give me the option to override which I then do. I will redo everything and again and post my findings. Thanks!
  11. Hi - Losing my mind here. Referring to the image attached. Cura 'has decided' that my materials are no longer supported. All of these were created by duplicating generic materials and then editing the settings. I went nuclear as suggested by another post in the forum and deleted the entire config folder. I then reinstalled CURA 5.3.1 and then recreated two simpler PLA materials, but I keep getting the error as per the screen grab. I know I can override the error but it does not make this any less annoying. Is anybody else experiencing this? @Smithy ?? Regards, Friedl.
  12. I accidentally stumbled onto something that improved this A LOT for me... I have a silicone soldering mat that, just to get it out of the way, I slid in underneath the printer once. I then changed filament and without noticing it, I placed the front "feet" of the printer on the mat as apposed to directly onto the desk. I would say this reduced the number of failures by about 50%. It is too small to reach all four feet, who knows, adding silicone-like vibration dampeners to all the feet might be the key 🤭 Regards, Friedl.
  13. This would be great, even it is is only material humidity-controlled chamber and not necessarily controlling 4 filaments types, even thought that would be amazing! Maybe if we can get this upvoted a bit more 😉
  14. Hi - I will add some and see. Thank you for the tip 🙂 Regards, Friedl
  15. Two more things to try; - make sure the cables (of both the front fan and the capacitive sensor) are twisted. If you have not removed them for some reason, they should be as I believe they are shipped this way. This for me had not affect. - For some reason after doing cold pulls to clean nozzles after printing with CPE, the printer printed without incident for a couple of days.
  16. Hi @Tim_Cochrane & @Kmmbdm1995 - I would agree with @Smithy, If you have the option to get it fixed under warranty, that would be the easiest (and best) way to het the matter resolved. I am not so fortunate so had to try as resolve the matter myself. Here are my findings; IMHO… It is seeming more like a combination of software/firmware/hardware issues as opposed to hardware only. I will stipulate my reasoning behind this shortly, let me first explain whats I have done in an attempt to resolve the matter, starting with the least intrusive ‘fixes’. I did every single calibration or levelling option the average user has access to on the UM S3. I am not sure whether there are more option when access development mode though. I opened the front access panel to the print head, cleaned everything using compressed air and made sure the the Print core tips are spotless. I cleaned the build-plate glass with lukewarm water and isopropyl alcohol to make sure there is no Magigoo residue. Removed all other electronics from the desk. After all these failed, I applied slightly more intrusive ‘fixes’; I disconnected all the JST connectors at the back of the printhead and reconnected them. I made sure the front fan cables are twisted. I applied ferrite strip to the back of the sensor (this had mixed results when running the Level sensor diagnostics test) I pushed the front fan cables all the way to the back as far away from the sensor as possible. (this together with the previous point had the level sensor test pass, but did not necessarily result in a successful print start) My findings; Regardless of what ever fix was applied, the best result was a successful level sensor test under the diagnostics section, but it did not result in a print start. The same errors appeared when attempting to print. When disconnecting the front fan cable, the level test is successful as well. Of course I did not attempt a print without the fan connected, so I cannot validate whether the print job would actually start. The only way I could manage to get a print was by following the steps below and this is where it seems firmware might also be playing a part: Start print job from CURA via Cloud. Wait for print to fail. Error messages vary. Do not acknowledge the error message on screen. In Digital Factory the print status will show failed. Do not interfere with the printer. The printer will then clear the message on the LCD display by itself and restart without any user intervention. When this happens, there seems to be a 25% chance of the print actually starting. If it still fails, Digital factory will show that the print has been COMPLETED and show the time it took (i.e 43min), even though it never printed. Then choose REPRINT the same print job that failed from Digital factory. The printer will restart the print job. Most of the time the first attempt will fail. The same applies as from POINT 3 onwards. Just leave the printer and do not select anything on the LCD screen. When it restarts the second attempt by itself, the printer prints, no errors and the prints come out successful. At least I have been able to get some prints done, but needless to say, this is not really acceptable for a printer of this caliber. It also takes quite a bit of time to go through this entire process to eventually get the print started. My question here though is that there is a definite pattern (at least in my case) which makes hardware as the sole culprit unlikely. If it was hardware error only, surely it should keep failing consistently. Hope this helps.
  17. Hi - Just got my Ultimaker S3. Bought it used but with only 72 hours on and in spotless condition with one problem.. Bed Levelling. In fails in any number of ways... Running Diagnostics: When attempting this I get one of two errors intermittently but it never succeeds: The capacitive sensor has low performance There is interference on the capacitive sensor signal When attempting a print: I have done due diligence here; manual bed levelling, lift sensor calibration, XY calibration, cleaned the print cores, cleaned the bed reset to facttor settings, updated firmware to latest stable build (or to latest) Checked the wiring on the sensor PCB as well as the connector at the back of the print head. Removed all other electronic devices from the desk Regardless, I still receive any of the following errors and it seems to be random: Active levelling could not be performed. Please check the nozzles and bed. Nozzle offset probe failed. Please check the nozzles and bed. Difference between detected height of both PrintCores exceeds realistic values Can't remember the rest... Then after hitting print around 5-6 times, it fails again but the without intervening, it restarts the print and then prints without a problem. I am at a loss here. I do not mind troubleshooting a bit, but these random errors are making it difficult to pinpoint the problem. Any advice would be appreciated! Regards, Friedl.
  18. @geert_2 - Fortunately I have a plexiglass door I made a while back, but the top is still open. I suspect a lot of heat escaped via the top... the while things about hot air rising and all of that 🙂 Yes, winter indeed. To make matters worse, we have a lot of rain in winter (in the Western Cape), so it can be really cold at times.
  19. Thank you for the heads-up 🙂 I also used the drawers for resistors, small ICs and Capacitors.
  20. Hi @UlrichC-DE - I do indeed have the 0.6mm and 0.8mm nozzles, only tried to use them once, but found the layer lines to be 'too visible' for most clients 🙂 I have no idea that 60mm is too fast of 0.4mm nozzle? I found some math in the forum on how to calculate speeds, and it seemed well within the capabilities of the UM2+. I will change these tomorrow and see how it goes. Looking to upgrade to UM3 or S3 soon, so maybe it will improve things a bit 🙂
  21. Great thanks! ugh... 50mm/s?? these enclosures will take all day to print 😄 ps: Did you try those drawers? I will be printing more this week. Have some components on the way, need to make place to keep them 🙂
  22. Thanks @Smithy - I am printing the PLA at 210C, 100% flow and 60mm/s. I will try printing at 200C and see how it goes, thanks. The sound is not too much of a problem, but I can see the knock-on affect on the outer walls as well. Not the end of the world, but would still prefer to 'fix' if 🙂
  23. @Smithy - Ok, so I built a thermometer posting readings to my phone so I can monitor the temperature. Without covering it with "something" it drops well below 15C inside the chamber. I covered it loosely with a black bag and temperature is hovering around 25C-26C. Prints are working. I do have one nagging problem I have been facing since I can remember. When printing larger parts like the enclosure I am currently printing, everything goes smoothly until I am ±50% up the side walls. I then start hearing these noises and it seems to be occurring when the nozzle is travelling to some some point to start printing again. It is also making these small bead-like deposits which then seem to be the cause of the 'rumbling' sound the next time the nozzle travels over that part. For the life of me I cannot seem to understand why the nozzle is doing so much travelling without printing. I suppose one fix is the keep the nozzle out of the infill area? Do I do this by turning combing OFF?? Regards, Friedl.
  24. @Smithy & @Torgeir - It does look good indeed. I will place an order today, will probably switch the CPE for ASA then, even though the video review on their CPE was very positive. With regards to my layer separation problem on both CPE and PLA the past two days... I think I might have confirmation on the problem... see image attached. Our min temperature today was 3C and max during the day was 6C 🥶 As I need to print this weekend, I will have to enclose the printer. Will leave the thermometer I made inside to monitor temperatures. Regards, Friedl.
  25. HI @Torgeir - Wow thank you, I will most certainly try this. I printed ` couple of time today with PLA and CPE but experienced more layer separation 😕 I cannot believe I have not done this sooner, but eventually grabbed some components and put together a quick thermometer to measure the ambient temperature around the printer. Outside of the printer (later in the day) I measure ±16C. It is very possible then that the temperature was lower earlier during my prints. I will conform this tomorrow. If your solution works for me as well, I will probably design a cover to include temperature control and air quality, so I can try our more filaments with strong odour when printing. Thank you again for the files! Have a great weekend, Regards, Friedl
