Guys I can not support hardware g540 or smooth stepper but if you got it all working correctly, wired and configured it will work as designed. Yes I tested and works on smooth stepper. G540 can't help you with that.
Lets keep this thread alife so I know of possible future modifications/ upgrades.
As of now version 3.4 is out and prior versions may not be supported.
Thank you for all your help.
