Title: Gearchange support Mach 3
Post by: Walkahz on May 08, 2023, 07:16:08 PM

Hi all.
I am just about to begin a conversion of A Deckel FP4ATC CNC from the late 80's.
I have figured out most of the requirements for the conversion however am undecided on 1 function. It has a gearbox controlled by 2 motors to allow for different spindle speeds. How would i be best to control this shifting inside mach3? I know it has been done in linux CNC using mesa cards to control the motors and a custom gearchange HAL however as i currently use Mach 3 on my converted round column mill I would like to continue to use what I know.

Thanks in advance.

The same way linuxcnc is doing it, the hardware is key, all that Mach3 will do is turn something on and off with M code macro.

Find out the details of the linux version and then report back with the details.
