I'm new to this.  I have built a custom CNC that has an additional linear axis on which the Z-Axis is mounted.  This additional longer axis is parallel to the X-Axis but above it.  I am planning on having this axis move into and out of the processing area so that it can be environmentally sealed.  I have connected it as though it is the A-axis.  Every thing is working quite nicely .  .  .  .  except Mach4 still thinks the "A-axis" is rotary.  How do I change it so that it knows the A-axis is linear?

General Mach Discussion / How to set up Mach3 so that B Axis controls rotation of the mill head

« on: January 04, 2015, 03:59:39 PM »

Hi all,
  I'm new to Mach 3.
  I'm trying to set up the program so that the program understands that "B" axis controls partial rotation of the milling head through 120 degrees (30 degrees CW and 90 degrees CCW), instead of controlling a rotary table that rotates the part to be machined along the B axis.  How do I do that so that the center of rotation is correct while also getting machine tool length compensation adjusted for etc.?
  Is this something I should be trying to solve in Mach3? in the SmoothStepper motion controller? or in whatever CAM program I am using to generate G code?

Respectfully,
