Hi all
After a couple of years, I am finally back and ready to making chips. I have a router, use steppers on parport. Linuxcnc is 2.9.4, debian:

Linux cnc0 6.1.0-35-rt-amd64 #1 SMP PREEMPT_RT Debian 6.1.137-1 (2025-05-07) x86_64 GNU/Linux

The router works, I can cut stuff etc. not the problem. The job that I want to do soon requires quite a few tool changes. So far I did it using the dowel method, but that is very time consuming. Sure an automatic tool changer would be perfect, but that's up for in a later stage. For now I have a tool length sensor, that I would like to use with my collet spindle to get tool length set after a manual tool change.

When I run tcdemo.ngc:

- goes to change position
- when I hit "Tool change complete", goes to zmax, tool sensor x and y, starts going towards the sensor.
- As soon as the sensor is touched, I get "Probe tripped during non-probe move" and program is stopped

How can I get over this?

I attach the relevant files in zipped folder "toollength_problem.zip"

Maybe have a look at the 'joint.N.unlock' pins:

Went to startup linuxcnc today and am getting the following error

If I comment out the
REMAP=M6 modalgroup=6 prolog=change_prolog ngc=change epilog=change_epilog
from my ini file all is well, but obviously no tool change.
With it in it eventually starts up after the error above but is unusable.

Chacking against git history show no significant changes that I can see.

Linuxcnc version 2.9.3
UI is Gmoccapy
Python version is 3.7.3

Unsure where to start.Update all

print

statements in your custom Python files (

stdglue.py

,

remap.py

, etc.) to use Python 3 syntax—i.e., wrap them in parentheses.Also check for other Python 2-isms:

• xrange

  ➝

  range

• iteritems()

  ➝

  items()

• raw_input()

  ➝

  input()

• Integer division (

  /

  vs

  //
