Yes it works perfectly. I would have to dig out the fix — it was suggested on the forum and the Pi5 setup has been flawless ever since.

Hello Have you been able to fix the problem in the meantime?I am also thinking about using a pi 5 + 7i96s as I now have a second PC which is apparently not suitable for Linux CNC. If you were able to fix the problem, what was the cause and are you satisfied so far?

Regards Erwin 

Hi,

I was just able to compile the scurve planner with the original linuxcnc Makefile system.

repository
Use the ./install script to install linuxcnc. It first installs the libscurve & libclothoid3d locally.

Then it just runs the axis_scurve_mm.ini config using scurve.

Hmm, interesting development.

Now a dev can make modifications to their needs, and merge it, if they want to.

I don't understand the problem here, really.

But with 1600 pulses per rev and a 3:1 belt ratio, the scale is just 1600/3 = 533.3333333333333333333333

If you see a creep, it could be the missing threes.

But, LinuxCNC expects pulser per _degree_ for a rotary axis, so you might actually want 1.481481481481481

Actually, hal_gpio might "just work" in this case.

Try this command and see if it reports the pins:If you get "command not known" then
If the pins are reported, then:
linuxcnc.org/docs/stable/html/drivers/hal_gpio.html

Note that unless the index pulse is from the spindle shaft, or the gear ratio is exactly 1:1, you can't peck-tap with the encoder on the motor shaft. This probably isn't a problem in most cases, but is worth being aware of.
