PWM not quite working

Hi, I have installed the EMC2 with the Ubuntu live CD and have successfully got my mill to move all 3 axis.

I use a Digispeed from Homann Designs to control a VFD.

Using the Step Config Wizard and reading the Integrator Manual V2.3, I have the following functions working on my mill.

Move all 3 axis.
Find Home and limit switches.
ChargePump.
Estop.
PWM for the spindle.

My problem with the PWM is that when I type into MDI "S1000 M3" The spindle works ok, if I type "S1000 M4" I get the correct signal to reverse the VFD but there is no PWM signal to the Digispeed.

The Integrator Manual says to do this--

loadrt pwmgen output_type=0
addf pwmgen.update servo-thread
addf pwmgen.make-pulses base-thread
net spindle-speed-cmd motion.spindle-speed-out => pwmgen.0.value
net spindle-on motion.spindle-on => pwmgen.0.enable
net spindle-pwm pwmgen.0.pwm => parport.0.pin-09-out
setp pwmgen.0.scale 1800 # Change to your spindle’s top speed in RPM

But the Step Config Wizard produces this--
*** highlights areas I'm not sure about that differ from above.

loadrt pwmgen output_type=0
addf pwmgen.update servo-thread
addf pwmgen.make-pulses base-thread
net spindle-cmd <= motion.spindle-speed-out => pwmgen.0.value ***
net spindle-enable <= motion.spindle-on => pwmgen.0.enable ***
net spindle-pwm <= pwmgen.0.pwm ***
setp pwmgen.0.pwm-freq 50.0
setp pwmgen.0.scale 7000.0
setp pwmgen.0.offset 0.0
setp pwmgen.0.dither-pwm true
net spindle-fwd motion.spindle-forward => parport.1.pin-14-out
net spindle-rev motion.spindle-reverse => parport.1.pin-16-out
setp parport.1.pin-01-out-invert 1
net spindle-pwm => parport.1.pin-01-out

This system is working on a demo version of Mach3. I hope to get my mill working correctly on EMC2 as from what I've seen it's smoother motion and cleaner screen layout appeals

I can attach the hal files if more info is needed.

My next challenge is to get my pendant functioning.

Thanks

I have the same problem...did you foud any solution ?

so...I did it...anyway...here is my HAL (attached)

no, it does not work...

in CW mode PWM works nicely but CCW mode PWM output has very narrow pulses...if I try to increase spindle speed...pulses become (pulse length is almost minimum) shorter and disapear at all...pwm works like an oposite direction...

thank you very much...it works

Hi!
I just fall into very similar problem, if not exactly same problem.
I need to basic PWM control of spindle speed.
One difference from standard setup is i use 'Spindle PWM' in Stepconf Wizard, but *not* use 'Spindle ON' signal, i write below why.
But after Wizard finishes, PWM output (i set it at pin 2) not work: This pin only now act as On-Off switch.
When i use 'S0 M3' pin becomes zero, 'S1 M3' or 'S1000 M3' gives continuous '1'.
I carefully read example in docs:but it is far different from that i see in auto-generated .hal file (please see attachment).
And because of difference, i can't properly insert this code in my .hal file, and can't test it, and can't test solution about 'loadrt pwmgen output_type=1'.
Q1: Is there an error in Stepconf Wizard, and should i ask about fixing it? Or it may already fixed in latest code tree?
Q2: Is there a (simple) way to fix .hal file by hands to get PWM out work?
Q3 (complex): There is common standard method and timing of PWM control exists for wide class of Electronic Speed Control (ESC) taken from radio-controlled toys world, and these ESCs used by some CNC DIYers for spindle motors. It all uses pulses like 1 ms = full reverse speed, 1.5 ms = stop, 2 ms = full forward speed. Period is 20 ms. (so duty cycle max. 10%). These ESCs don't have separate On-Off asynchronous input. Can it be used in EMC, and how i can modify .hal file for it? And maybe in far, far future i can hope that this particularly spindle control timings can be integrated in Stepconf Wizard?
Thanks!
