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

Thanks for confirming @Dustin. It has been working well for a while now.

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

@gr5 Thank you for the tips , I will look into this for sure!!

@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.

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.

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.

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

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? 🤷‍♂️

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!

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.

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.

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 😉

Hi - I will add some and see. Thank you for the tip 🙂 Regards, Friedl

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.
