I'm new to CNC, but I'm in the planning stages of building a machine.
I was going to have two rails for the X-axis, with a single rail mounted across for the Y-axis, which will hold the Z-axis.
I've been reading the manual for Mach2, and it talks about running two motors/screws per axis. It says the second motor will need its own axis to slave to the main drive.
I was planning on purchasing the FET-3 system from stepperworld.com
On their site, it says: "As an example of what you can do with the extra power, the FET-3 can easily run two motors in unison off each axis. (Two motors slaved together making identical or mirrored rotations is an economical way to drive a single axis with increased torque.)"
So, how will all of this work? It's a 3-axis controller, and the Mach2 needs an axis per motor? Will I have to ignore the Mach 2 statement, and run the X-axis pair as a single axis? Or do I need to purchase a 4-axis controller?
Will the hardware and software work together, or are they doing the same thing?
Anyone have experience in this? Thanks a bunch!
