Please be aware that since the PromaSD uses step and direction with respect to ground you cannot use the differential mode for step and direction. You can use +S +D and Masso Gnd as per the Proma SD manual. Do not common together the -D & -S but leave these disconnected as joning them together will damage these outputs.
Because PromaSD is completely stand alone you will not be able to use Masso THC commands as these are designed for Proma 150 type THC's and will not function with the PromaSD
Lastly you may need to modify your Gcode to compensate for the lack of feedback from the PromaSD. Masso will not know when the Arc has struck so you may need to allow time before starting to move.
I don't know if anyone has installed this THC on Masso to date.
Hope this helps
