I recently RE-retrofitted my Turret Mill. The machine used to have a CNC Masters retrofit which gave endless problems.
I installed 3 G202s on a www.cncdirect.co.za mach break out board. I run Mach 3.
The problem is that the machine will run happily for anything between 3 - 5 min and then the Y axis drive shuts down. The X axis drive shuts down a little later.
All the wiring has been checked and rechecked. The current limit is set to 120K and the fuse is set to 5A.
The servo wirning is as it was in the CNC Masters board. The CNC Masters board ran G201s.
I also checked the G202 temperature. The problem does not seem to be temperature related.
Could the problem be caused by having a parallel port cable that is too long?
I suppose the only way to see if it is the PC, break out board or Gecko would be to scope the drive data pins at the various point!
