Help with laser power control with M67/M68 pwm was created by TejasDragon
I am trying to get a laser running on my lathe with pwm laser power control. The lathe has been running for a couple of years
with XZ axis. I have it set up as a XYZA when using it as a rotary but just wright XZA to gcode. I have had it working fine using m62/m65 for
on/off. But I have had no luck getting pwm to work on it. If someone could take a look at my startup files and give me a clue
I would appreciate it.

You don't seem to have "addf"-ed the pwmgen functions to a thread.

Still do not have it, I have read through the docs, but at this point I do not get most of the way
Hal works. I added the "addf" like I found on a site that says this works for him. But when
I try to load it in the part that says
"net motion.spindle-on => pwmgen.01.enable"
It wants a signal name, at this point I have no clue.
The attachments are what I have in the current start up files.

Every "net" command needs a signal name. The format is
net signal pin pin pin pin pin
With as many pins as you want. The pins must actually exist. The signal name can be anything.
You can use the same signal on as many lines as you like. But each HAL pin can only appear on one line.
So, to connect one output to many inputs, you use the signal name, not the pin name.
Signals can be used to link pins in different files too, so for example:
In one file you might have:
net my-gui-signal mux2.0.sel
Then in the postgui halfile you can cpnnect that up with
net my-gui-signal pyvcp.button1
And that will connect a pyVCP gui button to a mux selector pin.

thanks for the help I got it. This is what made it work in the hal file.
loadrt pwmgen output_type=0
addf pwmgen.update servo-thread
addf pwmgen.make-pulses base-thread
setp pwmgen.0.enable TRUE
net analogout motion.analog-out-00 => pwmgen.0.value
net laserpwm pwmgen.0.pwm => parport.0.pin-01-out
