Hi there.. Sorry another noob question. currently im using 3 outputs on my bb (x,y,z) y is the split to two drivers to power the two opposing motors of the y axis. and currently only have one home switch on one side. Is there a way of using two home switches and utilizing the bb A axis output to mirror the Y output except when going home it will run into the switch independently? thus calibrating the axis back to square in the event of it drifting out. I haven't actually tested my home switches with mach 3 as yet.. do the switches also calibrate the axis, say the switch is activated at +0.2 will mach 3 zero the location? Cheers, look forward to your comments. Jon.
