I'll swap them both and see if that solves the problem. Otherwise, it'll be difficult.

A quick update from my end: I replaced the two components on the encoder board, but unfortunately, the encoder signal is still not being processed. Without a schematic, I really don't know where else to look.
I'm still waiting for the optocoupler so I can get the second board back up and running.

I replaced the optocoupler, and the output is working again.I attempted to set up the tool changer. Unfortunately, I keep receiving the following error messages when starting LinuxCNC. Attached is my .ini file.

Those seem like two separate issues, one remap is not doing OK and the other complaining about gcode, are you running the default "Linux CNC" gcode?

Thanks for your reply. What do you need to help narrow down the problem? I only adapted the `Toolchanger.ngc` file for my machine; otherwise, I haven't changed anything in the G-code.

We would need more info about what you want to do and what you already did.

Hello,
We created the `toolchanger_index_new` HAL file to map all the M-codes for `toolchange.ngc`; this kept things reasonably organized and allowed us to track what codes like M66 actually do.
Then we built the NGC file.
Once that was done, we integrated everything and added the remap section to the INI file.
When we started LinuxCNC, we got the error message mentioned in the previous post.
We suspect there might be an issue with the file path or something similar.
As soon as we comment out the remap configuration, everything runs without problems again.
The only exception is the `conv-float-32` converter; it used to work, but now LinuxCNC claims it already exists.
That is likely a separate issue and unrelated to the mapping setup mentioned above.

Hi everyone,
I’ve tried a few more times to solve my problem, but unfortunately, I’m not getting anywhere. Perhaps someone can tell me how to fix the issue so I can get the tool changer up and running.

1. These two errors are connected. The parameter #<_tool_in_spindle> is not defined because 'change_prolog' cannot be found.
2. Looking at your ini file it seems that your paths are messed up. TOPLEVEL should point to the file 'toplevel.py' not just some folder:
Since we don't have your complete config folder there is no telling where you have the relevant files but if you compare your setting with the built in 'sim/axis/remap/extend-builtins/' you might get some ideas.
(You will find the [PYTHON] section at the very bottom of the ini file below):
github.com/LinuxCNC/linuxcnc/blob/2.9/co.../extend-builtins.ini

Hi, thanks for your help. Unfortunately, I misunderstood something last time. I have uploaded my complete LinuxCNC folder as an attachment.
