I have a Tormach PCNC1100 and I want to hook my 4th Axis up to my Machine because it has good clearance for my Tool changer. I ordered the proper Motor and stepper driver from Tormach, the problem is they will not tell me how to go into Pathpilot and change the Axis[3] Scale.. They have a 90:1 gear ratio and I am going direct drive because I am only doing light engraving on a cylinder. Does Anyone know how to Hack into PathPilot? I need to get this to work and hope it can be done... Thanks in advance, Bradly
