+Starting operation with positive pitch forms left hemisphere, with negative pitch - right hemisphere.
 
 Set the desired pitch to a suitable value e.g. `0.07mm`. All soft limits (left, right, up, down) must be set before the operation can be started.

 Turn on the spindle. Operation will proceed fully automatically and the cutter will return to the starting position when done. Adjusting the pitch on the fly is not supported.
