Hi Bill, I have the MK2 and would like to upgrade to the MK3 including the new firmware. Can you put together a kit including the MK3 parts upgrade and the control board preprogramed with the new firmware. I do not have the parts or expertise to do the firmware myself. I'm in Canada. Thanks

Hi Bill, will the upgrade parts (Mk3) be available to everyone. I too suffer in silence with the feeding and retraction inconsistencies.

I've been able to get my Ender3 V2 with MicroSwiss direct drive to work with the following settings for tip formation and extraction. ; quickly retract the filament to shape it G0 E-50 F10000 G0 E50 F2000 G0 E-50 F10000 G0 E-35 F50 What this does is extract the filament just into the plastic tube between the hotend and extruder at high speed then pushes it back down to the tip, repeats the high speed retraction then slowly retracts to cool out of the extruder gears. I found the tubing from the extruder to the Y need to be at least 2.0mm IDO so as not to jam because the best shaped filament tip I've been able to get is 1.95mm in dia.
