Mach3 How to use A Axis(Stepper) as Spindle?
« on: October 15, 2020, 09:18:56 AM »
hi!

i have bought a rnr motion control eco v2 usb unit.

this unit not support dir/step on spindle.

now i want to use my A Axis as Spindle.
my A Axis is a Nema34.
i know that a stepper is not a good choice.
i want to test something and play arround.

i read that SwapAxis(3,6) change the A Axis to Spindle.
but if i enter this in the commandline in Mach3 i got an error.

how is the swapAxis function to use?
where do i enter it?

thanks

it is to use in a VBScript.

Operator -> VB Script Editor
anything is possible, just try to do it.
if you find some mistakes, in my bad bavarian english,they are yours.

Where did you read that you can swap axis with the spindle ?? The spindle is not classed as an axis so I do not believe what you want to do is possible in Mach3. Even IF it worked when you swapped you would NOT have a normal spindle operation. I have done cylindrical grinding AND offset grinding (cam grinding ) with mach3 but it takes special considerations in scripting(macros) and CAM to make it all work.

Just a thought, (;-) TP
