What is the spindle speed?

After setting the RIP environment, does linuxcnc start?
Just type linuxcnc and hit enter.

Yes of course, here is detailed wiring and testing and tuning howto, let me know is something seems strange or i might improve.
Thank you.

Looking good

I assume this is the same issue:

2.10.0-pre0-3740-g5ec17ac2b8

The only way I've been able to reproduce it consistently is by starting and then stopping immediately, but when I recorded this video it happened without fail.
I think it's related to how the state is restored from a state tag after an abort(?).
If I comment out emcTaskStateRestore(); at line 2078 in emctaskmain.cc the spindle doesn't restart.

The python3-distro library is in all the recent Debian releases so I'm confused why you don't have it?

The problem was that I had pwmgen.00.offset-mode set to 1
Once I set this to zero, now the voltage is correct.
I've set the pwm_frequency to 5000 initially, then after your last comment, I increased it to 20000, but didn't noticed any difference.
Not sure what this does exactly and why would it matter if its higher.

Thanks for your help so far!

Not unless it got there from the easy probe I tried to install.

Thank you for your help, I have had a sick feeling since this started, not because of the lost part but because it didn't seem like I would find the answer. Thank you for helping!!

I have been using the machine for 3 years now. I have even made these parts before. I will post the files in a few.
It does not do this all the time mind you.

net probe-in => motion.probe-input
net probe-in <= parport.0.pin-11-in-not

this should be all you need for the input in your main hal

are you in the sim?

Is it possible to use spindle synchronization with only one initiator that monitors the spindle speed?

Yes. No need for anything particularly clever.

loadrt encoder
...
addf encoder.0.capture-position servo-thread
addf encoder.0.update-counters base-thread
...
net pulse-index-combined parport.0.pin-NN-in encoder.0.phase-A encoder.0.phase-Z
setp encoder.0.counter-mode 1
net spindle-position encoder.0.position-interpolated => spindle.0.revs
net spindle-velocity encoder.0.velocity => spindle.0.speed-in
net spindle-index-enable encoder.0.index-enable <=> spindle.0.index-enable

Basically connect phase-A and phase-Z of the counter to your parport pin, make sure that you set the encoder to counter-mode and ensure that you use the position-interpolated pin to smooth the motion.

Hello.
Is it possible with this one index signal make a spindle orientation always in one position?
Spindle stop at the same position after index input goes active.
I'm reading out now with this example the current rpm of the spindle. (just on a mesa board 24v input)

thanl you for replay , but i want to use arduino with 600ppr encoder can i

So when using the clothoid filles, a divided trim is a signal to not add a trim segment to it. As this can result in going trough
the workplane.
Otherwise when using the bspline fillets, this uses a set off controlpoints. I suggest that bsplines are still valid, as they don't need
to solve the G2 problem.
Line fillets (chamfers) are still valid.
