I installed the latest firmware and immediately started having prints that have failed in catastrophic ways. Finding the whole print bed shifted and a huge blob of plastic on the hot end. This has been with PETG and PLA+. And in most cases I had just checked on the print at about the 14-hour mark, walked away for 30 -45 minutes and came back to it failed. I suspect that the bed level function is not performing as expected. That said, I have no doubt that my bed is not flat and I also just replaced that about a dozen prints ago. I also have the original bed frame, suspect that is contributing to my issues, but I was getting successful prints prior to the update. Before I could get it dialed in and just start prints and walk away for several prints, normally didn’t have to mess with it again until I swapped out the filament, now I will get one print that is sucefull and the very next one will not stick to the bed.
For troubleshooting: I have swapped where the rails were, due to noting that one of my Z rails would allow the Y-axis to drop at least 1mm. Verified twice now that everything is put together right. Performed several auto levels, and I use a feeler gauge for getting the correct distance from the nozzle. I have even attempted a manual level. The last fail destroyed the hot end cause I thought it was sticking to the bed and went to bed, woke up to the hot end bing in a huge blob of plastic that melted the insulation off the wires. I was really lucky I didn’t have a fire. I just replaced that (which kudos to snapmaker for making that 100x easier than it is on the 1.0 version) and am in the process of rolling the firmware back now. Anyone else experience this or am I one off?
