General Mach Discussion / More inputs or can I configure Mach3 to use one MPG for X, Y and Z axis?
« on: September 20, 2017, 10:43:37 AM »
Newbie here with a couple of questions......
I'm adding CNC capability to an old Long Chang mill, so far I have added 1200 oz-in steppers on the X and Y axis , and I'm driving these with 2060AC micro stepper drivers via Mach3. I also added magnetic scales for DRO capability. Everything seems peachy-keen so far, other than some motor resonance at medium speeds. I will Add Z axis capability next.
I'm using a dedicated mini-ATX PC board that has two parallel ports.
I also want to hookup a rotary pot (MPG) to make jogging easier. At first glance it looks like Mach3 is designed to work with separate MPG encoders for each axis, I would prefer to have one rotary encoder and a rotary switch to assign the encoder to the desired axis. Is there a way to get Mach3 to change the axis a single MPG will be used for?, ie. a command would be ideal. If not I will need 2 inputs for each MPG! I'm quickly running out of inputs:
1 for E-Stop
2 for X axis DRO
2 for Y axis DRO
2 for Z axis DRO
So if I can mutiplex 3 MPG's to just 2 inputs (I'm okay for now), if not I will need at least 3 more inputs.
2 for X axis DRO
2 for X axis DRO
2 for X axis DRO
How does one get more usable inputs?
