OK - but whatever systems you're using, "somewhere" you must configure Mach with axis step and dir info so my thinking is you make them all the same. Maybe not. I'll get back in my box  ;D

Not really, the plugin for the CSMIO at least, will only allow you to configure a channel  once.
For example if Axis 1 was on Channel 0 and Axis2 was on channel 1 and you switched axis 1 to channel 1 then Axis 2 channel would be disabled until you configured it as something other than channel1.

Ah - understood. Thanks.

Just tried it here for the hell of it with the PP and unlike your CSMIO - Mach doesn't give a monkey's - all three axis pumping steps out of the same pin.

Yes, think even the ESS and SS are like that now, Dan got Greg to allow that in it as at the time SwapAxis() was not enabled.

Even if it was possible I think you may run into  issues with the analogue as each encoder is monitored and the control is constantly sending out small voltages to keep it where it is meant to be, have all 3 sending to the same pins and I think it would be chaos.

There you go then... replace the motor with a big FO stepper and use the PP port - (is joke).

I'll leave you to it - but if you need any help don't be too shy to shout up  ;D.

I am never shy about shouting, I was one of the 45% ;)

Thanks for the tips.

So, there is no way I could solve this elegantly in mach itself. It would be cool if someone with knowledge could write a plugin for CSMIO/IP-A or Kflop with Kanalog with that functions. Another, more expensive way is to buy three servo drives and motors...

Best way would be 3 servo drives, would make it a much more useful machine.

Regarding someone doing a plugin, dont think there is much chance of that unless you do it yourself as it is highly specialised and not likely many would use. You may be better talking to the guy that makes the Kflop, he may be able to suggest how you could use it with just a bit of coding.
