CSMIO/IP-M and slave axis functionality

[EddyCurrent]

I might look at alternatives (ESS maybe? Does that do slave axis homing properly now?

Yes, this version of the driver, ESS_v10r2d1d.zip , has been working fine for ages now, the previous version used to give me problems. I'm using two motors X and A as slave but I only use one homing switch on the X side, I might fit two at some stage but as yet one works fine.

Eddy - how do you cope with the possibility that the steppers lose position when you switch off, so that possibly the gantry goes slightly out of square each time you switch on? Or do you square it manually somehow from time to time? I thought that that was the advantage of two homing switches. Or does practice trump theory, as is often found?

I think you need two homing switches. I use the Pure Logic PLCM-something from Zapp and it home very well with the two switches but I have to set it up by adjusting one of the switches to get the gantry squaring correct, after that it sorts its self out at every home position. ..Clive
