Hey all, I just got a new bed from Snapmaker a few weeks ago and I’ve started experiencing some combination of problems related to leveling and bed adhesion (dual extruder). It’s been slowly getting worse to the point where I can’t print without problems. I’m not even trying to dual extrude most of …

Perhaps a stupid question: Did you clean your printbead thoroughly? I recommend giving it a wash with a wet cloth and dishwashing soap ever once in a while (of course using just a wet cloth to remove the soap again, and dry it off), and also Isopropanol right before printing.

I recently did give it a quick wipe down with ipa but I don’t actually wash it or anything like that. I just came across a post of yours about the 11x11 calibration, I think my next steps will likely be that calibration and a washing. I’ll post back here when I try that, @nweolu ’s post also gave me…

Very disappointed to see that there’s a firmware issue that prevents me from running G1029A. I abandoned the 11x11 calibration attempt but would love to get that working eventually. Unless I missed a resolution somewhere? Instead I just reinstalled my heated bed as was discussed in the above post a…

[image] Jameracho: Very disappointed to see that there’s a firmware issue that prevents me from running G1029A. That’s what worked for me, I think past then with a 1.14.x firmware: 11x11 calibration with heated bed possible? - are you saying this is not working anymore?

It didn’t when I just tried it, specifically the G1029A gives me an error something like “cannot run without 3DP”. Ie, the dual extruder is not recognized as a 3D printing module. Doesn’t matter what I set the grid size to, I can’t actually start the calibration even if I’m connected to the machine …

Gosh! That’s stupid… so they really implemented their own levelling procedure for the dual head… Why??? I noticed that it has a different pattern, not spiral, but scanning lines… It seems they failed to add heated bed levelling to Marvin standard leveling procedure, or what? I’m not amused…

Yea, my thoughts on Snapmaker swing back and forth over issues like this. In general I love my machine and most aspects of the designs are great, but I don’t think they invest in proper software engineering and quality control. Those two areas seem to consistently disappoint through bugs or just lac…

All the credit goes to @Mxbrnr for his effort in writing the leveling guide. As for the leveling, dual extruder is a different animal, I hope you will fill out a ticket with support to let them know it’s important to keep the firmware consistent - Support Ticket Form Also, check this out - Dual Ex…

Yea, that’s the post I found that made me realize that it’s possible to make my own firmware modifications. It’s somewhat terrifying since that also means I can fry my device with a bad update, but very happy that it’s open and possible to dig around in the code. Ticket filled, although not sure it…
