Hello together, I just wanted to report the current status. We got our printer back and the supplier reported that the printer worked flawlessly. The returned several perfect benchies with it. What shall I say? I connected up our printer and it worked since then. Same settings as before, same models, same GCode. I have now printed one 750g roll of PLA without issues. (OK, a big printout did show a slight warping which I could fix by increasing the bed temperature and thoroughly clean the bed with IPA). As expected the print quality is very good. I don't like really knowing what the root cause was, but since I am a little under pressure of getting the printouts done, I am happy that it works. Hope it will stay that way. Best regards PiJey

Hi Bossler, hi kmanstudios, yesterday, "this person" actually sent the printer back to the reseller for repair or replacement. I had a talk to them and actually already did, what they requested me to do, thanks to the good answers in this forum. I selected this printer for it's excellent reputation for quality and professionalism. It was not me who brought the flakey power brick into play here. But to be honest, this is a power supply produced by some company far east, and they also build to price. They also calculate a certain failure rate. Show me any company which doesn't. Nevertheless, the printer is not working correctly and it is definitely rebooting, I could verify this in the logs. I definitely did not "try any unreleased firmware", the problem existed from day one, after the unpacking and startup as described in the supplied papers. I can only stress that the part of the benchy that was printed was of good, even exceptional quality. But that does not help me. I also need to do prints of 12 hours or more. The power in our offices is OK, no crashed computers, no heavy loads, no motors in this pure office environment. A colleague in the neighbor office monitored the printer via it's camera, there was no power issue during that time. Usually, our power network is fully reliable. I do not remember one power failure or even flicker in this building for the last 5 years. I don't think that a UPS is required. Guys, this is an office building of an IT company! Face it: In the real world even the best products fail sometimes. It seems that I am the lucky guy who got the failed one out of n thousand. Could have happened to you as well. Please be careful with accusations. Thanks for the help so far, I will report the outcome when the printer is back. Best regards, PiJey

Hi all, I sliced a benchy without heated print bed. I used blue tape to get the adhesion and it worked well. Unfortunately, even without the heated bed, the printer was not able to finish the benchy. It got further, though. Please see the attached pictures, see the bottom benchy. I'll return the printer to get a working one from our supplier. Best regards, PiJey

Hi gr5, I just bought blue tape to be on the safe side. Thanks for your help! I'll report how the print goes through. PiJey

Hi gr5, thanks, I'll get some. From what I read, the "original" blue tape is the 3M / Scotch 2090, probably due to the temperature range. I wonder if using just Glue-Stick on the cold glass build plate for PLA would be sufficient for a test print, if I monitor the adhesion of the first layers? Looking forward to identifying the issue, PiJey

Thanks for your quick answers. @gr5: A power supply issue sounds plausible. The power in our office is quite reliable, I never heared of any problems with other devices. I read some posts here in the forum that seemed to have similar issues and the power supply was mentioned. Since the printer is brand-new, we will get another power supply on warranty, I guess. Using Blue Tape and switching off the print bed is a good idea to verify it. I will see how the return process for the power supply works and see what will be faster. I just worry that the printer will "improve" and just reboot later. But we have to start somewhere. @fbrc8-erin: Yeah, I would have to borrow or buy some. But if it verifies the issue, it is worth it. I checked the plug after reading about this here in the forum but it sits snug in it's socket. Thanks again, PiJey

My company acquired a UM3E for producing technical prints. After connecting it up and doing the initial steps connecting up the printer to power and network (Ethernet). I tried to print a simple benchy, print out from USB-Stick. The printer stopped printing after roughly an hour with a print that was about a centimeter high. The display showed the message "Print failed. Carefully remove the print from the build plate." The only option was to select "PRINT REMOVED". BTW, this does not make much sense, since the nozzle was still touching what was printed out, up to this time, so removing was quite impossible. What actually happened when I clicked the button, was that the build plate moved to the bottom position. The print stopped at around 10mm height. Please see the attached pictures. I retried the print with other objects, e.g. the ultimaker robot and others. Usually the print failed somewhere around 10mm but not exactly at the same point, especially when using the same g-code. We tried different USB-Sticks, different models, all sliced on the current Cura 3.1 set up for UM3E. There was only ONE object so far that worked, probably because it was flat enough. Even with that object we got the same error message. The part that was printed, actually had very good quality. The print had perfect adhesion to the print bed. Dimensions and surface were good. When checking the logs, I found out that actually at the point of failure, the printer rebooted. This was also backed by a colleague, who observed the print and lost the camera connection at exactly the time of failure. I don't want to upload the log files in public, since company data is generally confidential, sorry. The firmware was updated by the printer via network to the current release firmware without problems before the test prints. I installed the newest test release firmware this afternoon, but I am not very confident that it helped. I am quite disappointed in this printer that I recommended to the company. Would you have any Ideas how to fix that issue? I need to print objects that will take about 12h to print. Stopping after less than one will not really fit the business model.
