What happens if you remove everything related to the spindle (and especially the tormachspindle component) and put in the spindle stuff from your working config?

They are close to fixing, it lacks to adjust the actual speed to the one set.
Now it is 200 in PP and the spindle rotates to 200, imposed 500 in PP and the spindle turns to 3000.
How can I make this adjustment?
PP 200 spindle 200 PP500 Spindle 500 ............
My renge is 200 min 3000 max

Thanks

It should be possible by adjusting these lines:
setp pwmgen.0.scale 2830.50847458
setp pwmgen.0.offset -0.0674251497006

Though, frankly, that looks about right.

I had already added but did not solve it.
I attached file for your evaluation.

Thanks

You should try changing the values to see if it makes things work better.

You can do this "live" to save rebooting LinuxCNC, then put the new numbers in the HAL file when you have the correct ones.

open a terminal after starting LinuxCNC

halcmd -kf
This will open a HAL session. (Hopefully, if PathPilot hasn't disabled it)

setp pwmgen.0.scale 3000
This will change the PWM scaling.
Use the up-arrow to bring the command back to try a new value.

exit to exit.

But your HAL file seems to still have lots of Tormach spindle stuff, and lots of commented-out copies of the VFD stuff, so I can't tell if it ought to work or not. It's a mess.

I have tried any type of code, I'm mistaken or does not make any changes.(As a beginner)
I do not know what to change.
I came back to Tormach configuration with some modification.
Now it works like this 200=200 210=220 220=240 230=260 240=290 250=350 260=1010 270=2460 280=3000 (Set = Real)

If you still have some advice and well I accept

Thanks

You could try using a PID to run the spindle in closed-loop speed control (if you have a spindle encoder).
Or, possibly, use the HAL "lincurve" component to map between desired and the command required to give that.

I wonder if your PWM frequency is very wrong?

PCW

According to your opinion this firmware is usable with the C11GS.
Run the forward and reverse spindles.

PCW

To find a proper firmware for my C11GS, you work with Pathpilot where you can find or do it.
You saw what I posted on Saturday.

Thanks
