I just noticed that the file I attached had a date appended 'remap_2026-07-11.py', this date needs to be removed.

So make sure you go to your 'python' folder inside your config and rename that file to 'remap.py'.

I checked the folder name again today; it was correct—without a date. I also have the latest Python3 version, 3.13.5-1. The error persists.

Hi everyone,I’m persisting in my efforts to get my machine finished using various methods.We’ve been trying to work with `carousel.comp`, but we’re running into issues with positioning the carousel. The cam limit switch is connected to Pin 28; it indicates the home position and is wired as Normally Open (NO). Pin 12 is connected to the proximity switch used for positioning the drive motor. It’s an NPN sensor: the contact is inactive when the cutout (missing material) passes by, and the sensor activates when material is present. Image 2 shows the program sequence as displayed in the screenshot. The problem arises when the cam limit switch (Pin 28) is triggered: the motor shuts off, but the carousel ends up positioned between two pockets. The motor needs to rotate another 180° so that the cutout aligns with the sensor. Image 1 shows the correct position—with the cutout aligned to the sensor (Pin 12)—even though the limit switch (Pin 28) has already been cleared.Can anyone suggest a solution for getting the positioning right?We’ve tried using "NOT" commands within `carousel.comp`, tried to wired as NC but haven't been able to resolve this specific issue.

Which version of "carousel"? The newer version supports a slow-speed search for the index marker. 
Settting decel-time and align-dc should activate this behaviour. 
linuxcnc.org/docs/stable/html/man/man9/carousel.9.html

If the sense of the index marker is wrong, then you can typically connect to the inverted HAL input signal that most drivers support. 
For example Mesa cards have pins like hm2_5i24.00.7i64.0.0.input-00-not which is an inverted version of hm2_5i24.00.7i64.0.0.input-00
 

Hi everyone,

after a lot of back-and-forth—and some inexperience on my part—I’ve finally got the tool changer up and running. Many thanks for your help. Now just a few optimizations remain, but the bulk of the work is done. Next up are the 4th axis, the central lubrication system, and the spindle oil cooler.
