The Second gen snapmaker is quite the unit, however in inherits a few annoying bugs from the first snapmaker.
The first is that calibrations pre-print should be done with an at-temp buildplate. I used to trick my old snapmaker into doing this over the USB connection then quickly calibrating it while the plate was still hot. The new one auto-calibrates before prints, making this tougher to pull off.
The snapmaker should bring the plate up to full temp THEN do the calibration, as the plate will have reached it’s final shape. Then it can go check stops and such while heating up the hot-end.
The second is to have some sort of filament guide, retraction spring (you can find these on thingiverse), as long moves on the Z-axis can cause the filament to fall off the spool over one of the z-axis linear modules.
I’m sure I’ll have more, but this is my immediate feedback.
