Hi there, I am building a wood turning lathe, two axis X and Z, using the Mach 3 usb controller two stepper motors ,two power supplies, and two M542 stepper drivers, I have wired the motors and drivers etc. connected to Mach3 Turn, using the key board short cut keys and the pendant the motors turn nicely in both CW/CCW directions, one motor at a time by pressing the appropriate keys etc, but I can not make the two motors to turn simultaneously by pressing the two appropriate keys at the same time, tried all the setting in config screen to no avail, is there something I have missed, I can turn each motor in both direction but only on at a time. Any information will be greatly appreciated.

Regards
Nick

this Problem is caused by your USB Controller, we had this a couple of weeks ago. there are controlers witch Support
two axis at a time and some others do not.

Thank you TPS, I thought it may be the problem with the USB Controller.
