Hello everyone,
I’m sharing the configuration changes I made for my Snapmaker 2.0.
I changed the startup G-code because the nozzle wiping on the bed causes issues with certain filaments, and the “if 1=1; then reconfig Z0” messes up my calibration.
Here is the corrected G-code (Note: this only works with a module that has a single extruder):

I have put comment on if before to correct it 
Additionally, I’m sharing my “optimal” and “fine” configurations, which still need optimization but correct an excessively high speed and, more importantly, a sudden acceleration that causes errors between layers.
If you can help me improve, I still have issues like this that are frustrating me: (perhaps it is the PETG filament)
