Hi there
A lot of times I extrude some material for testing and adjusting in front of an actual print.
Since a while I have to shut the printer off again before I start the print. If not most of the time the extruder retracts a lot of filament after zeroing the z axis.
That happens with ocotprint and simplify3d.
Printer: Makerfarm Prusa i3v 12"
Controller: Rumba
Firmware: BeckDacks
Any ideas?
