Update to driver problem!. Just done the latest Windows 10 update (version 20H2) and also chose all the optional updates and my Ender3 v2 printer is now recognised and working fine with Mattercontrol. !.
Same thing here, found this as I was pulling my hair out trying to figure out what's wrong with either my computer or how I was doing it. The lifting trick didn't work for me similarly have put a few days into a design (probably the most complex thing I've built so far) and now can't finish it. It just hangs on "Split faces 2" for me. Does anyone have a solution? Are there other good programs out there that would read the .mcx files??
@larsbrubaker thanks! The only place I could ever find was after already installing MC. There was even a forum message about that exact things some weeks back and the only mention was in MC.
As for the profiles issue - it affected all my slicer profiles - solid, 35% file with different bottom and top solid areas. I was able to fix it, but only after I figured why my prints started shifting.
@hamprinter Thank you! I just figured that out myself last night as well, came here to post that was the cause. Hmm. Feel like that setting maybe should be grouped with the speeds, but thats a UI question.
OK, this appears to be a problem with the baud rate after all. I was able to work around it, once I discovered that even thoughg it did not connect, I could manually set the baud rate in the printer profile (in this case to 115K).
Now it connects.
I like MC for the mesh modifications; that are easily done inside it, but for any sequential printing or complex slicing, I use Prusa Slicer or Cura.
I would try and find a "preset" for your printer for either of the two mentioned programs.
Does your printer use bed leveling through MC?
