I went back and looked compared my wiring to the above text diagram from
Kirk and found I had things wired pin 7 and 9 reversed - fortunately I
didn't fry the G540 because of it.
Thanks Kirk for the clue!!!

How about a G54 stepconf file:

Copy the file into ~/emc2/configs, run

I have a mini mill that's using a G540 controller run by the current version
of EMC.

Does this mean that this upgrade is a not recommended or possibly

No, thats's just not right. The PWM frequency is set by the frequency
parameter, which I forgot to include in that HAL snippet.

The PWM frequency will be determined by the thread rate that the PWM
component is loaded in - usually the servo thread or 1kHz (?). The G540

In either event, as you say above, the control from the computer needs to
