My current setup consists on a gantry with both sides driven through a drive shaft with one motor. There are limit/home switches on all three axes. They are all NC switches and connected in series. Homing and limit functions work well and as expected. I'm thinking about losing the drive shaft and going to 2 motors, so I'll have A slaved to X. Ideally, I'd want to just add another switch to the A side of the gantry and wire it in series with all the others. Will this work properly for homing the slaved axis or are two independent home switches needed? What I'm after is for the gantry to square when it is homed.
One problem I can see is if X and A are homed together and the gantry is close to square, X could hit first then A could hit before X has had a chance to back off it's switch... Or would A stop when the X switch makes contact, wait for X to back off then continue? I'm low on inputs, so trying to figure out if this will work before making any machine changes...and trying to avoid the low tech method of squaring (Turning off machine and pushing the gantry against hard stops.)
Thanks
