Gooday from Sydney.
I have recently built a four axis gantry robot running Mach3 software.
It uses a four motor parallel port hobby cnc controller, and runs on windows 2000.
I am building an extruder and want to know how to make parts with this rig.
I have four active stepper motor channels and motors working.
Mach3 can control up to six channels.
The real question is how do I assaign the b or c axis to driving the extruder?
Has anyone been down this path?
Thanks Peter.
