Always works. You must set the speed at least a line prior to issuing
the
M3 command.
Huh? I have

Not as far as I know. I am pretty sure that Stepconf ought to do all
that
Hi all,
I'm attempting to set up EMC2 to generate a PWM
signal for spindle speed control. I put a DVM on the
PWM parallel port pin in hopes to see an average
voltage of the PWM signal. But all I see is about 90mV,
and it never changes.
I tried MDI commands like:
M03 S100
and
M03 S2000
I'm

Huh? I have NEVER done this, I ALWAYS code it on the same line, either
in my .ngc program
or with
