  1. Thanks for the info. My hotend is not clogged so it's basically working, the problem that still remains is I have some drippings that appear on the model. I am reluctant to take everything apart as it was quite complicated putting it together in the first place. I remember like I tigthtened everything nicely, but maybe I didn't 🙂 I'm gonna continue using it like this for a while and see what happens.
  2. Same thing happened with my UMO+, I had to reinstall the firmware coming with Cura 3.5.1.
  3. Hi, See the attached photo, it seems like the is extra filament melted there. It also looks like dripping from the side of the nozzle, although it's a brownish looking goo, not silver as the filament.. Do you need to take the head out and clean it? Any suggestions what I should do? The problem I see is that the filament is not feeded through to the head, looks like it's clogged somehow. It works when I use the manual axis movement for the extruder head motor, but during a print, even though the motor and wheel are turning, the filament doesn't move further to the head. Thank you.
  4. I managed to get it fixed. It seems that there is no firmware installed by default on the controller, so the first time it boots it looks like this. You need to connect it to Cura over USB, and there use the Upgrade Firmware button on the Manage Printers screen. The printer would say "not connected", but the firmware did install and then it booted correctly. Once you have the firmware on, make sure the EXT1 and EXT2 cables match what's on the board, I messed around with them trying to get it fixed and at first it looked exactly like before, all blocks. But when I put them in the correct position, it loaded up the text UI. Hope this helps.
  5. Hi, I have assembled everything but when I turn on the printer, all I get on the controller display are some blocks, then nothing happens. I tried every possible combination of the EXP1 and EXP2 cables, with no result. See attached screenshot. What can I do? Is there a faulty component? Thank you. Radu
  6. Hello, I have the exact same situation. Did you get to solve it after all? Thank you
