High Low Gearbox Bridgeport

DOes anyone here have any experience setting up a 2 speed gear on a bridgeport to run under PathPilot or Linuxcnc ? The spindle direction reverses when you shift to low range and there is a 1:9 reduction in spindle speed.

That will be my next project for the BPCNC mill. Just looking for some example code as a guide.

LinuxCNC has a rather limited 2-gear HAL component. There are others around that do the job better, but this one is the default, and was written (I believe) specifically for Bridgeport mills.

This post has covered a good amount of gear change, tool change and orient stuff on BP VMC

I found an example of just about everything rolled into a Hal. Look down near the bottom of the listing. forum.linuxcnc.org/10-advanced-configura...-gearchange-and-near
