hi guys and gals. im looking at adding a 5th axis to our foam cutter. 5th axis= rotating table. we are using a hot wire foam cutter xl with 4 axis. question- how would i go about adding it in mach4?

Hi,
easy, just add another motor with the appropriate tuning values.

Remember that Mach4 does not have kinematics, so your code must be composed without relying on Tool Center Control (TCP), as Mach does not have that, and to my knowledge never has.

I have a fourth axis (trunnion table) and fifth axis (rotating platter). Getting them to run is no trouble, but and this is the big but......the Gcode must be composed (CAMed) with the center of rotation
of the machine (where the fourth, fifth and linear axes all coincide) with the part origin. This requires careful thought that the part origin be exactly coincident with the center of rotation.
