#max_extrude_only_velocity: #max_extrude_only_accel: # Maximum velocity (in mm/s) and acceleration (in mm/s^2) of the # extruder motor for retractions and extrude-only moves. These # settings do not have any impact on normal printing moves. If not # specified then they are calculated to match the limit an XY # printing move with a cross section of 4.0*nozzle_diameter^2 would # have.
