No, this isn't the usual question about Mach3 settings for slaved twin X-axis homing.
I'm upgrading my cnc machine to twin X-axis ballscrews on the gantry. My new home switches have arrived, and reading the Mach3 manual and around the web shows me that I can independantly home each ballscrew to straighten the gantry. All fine.
But what I had been expecting was that you could tell Mach3 how much to back off the switch on the slave side, to tune the final position and make it perfectly square. Otherwise it would seem that you need to design some kind of micro-adjustment on the slave microswitch to fine tune the position.
Can anyone tell me which of these options is required - I was expecting to get the switch pretty close mechanically and then fine tune the amount of back-off in software to get it dead on.
Thanks
