Ehm, dangerous tool... It does not accept z_offset #31

Describe the bug Well, I thought I made a mistake by myself... But after 2 tries, this tool basically changed my Voron 2.4 into CNC 2.4... So, first of all. I was able to use "without a problem" this calibration tool with TAP. Unfortunately, because of the weight, x position, vibrations, speeds, I moved back to "original" inductive probe (Inductive probe is working fine). I followed again the guideline from scratch (first layer was calibrated by "paper" and later on I went through the first layer squish, I set the correct z_offset). Printing something is without any problem. Unfortunately, when I used the calibration tool (pattern method) to calibrate the pressure advance, after generating the gcode and printing it, the nozzle simply scratched the printing plate... I was soooo f***ed up on myself, but I thought I made some mistake with the settings. I set everything from scratch again and the same... That nozzle is printing like 0.5-1mm bellow where it should.

Klipper Error Message (if applicable) N/A

G-code File pa_pattern.gcode.gz

Screenshots Well, the only screenshot of this CNC I can provide is how the printing plate is scratched and you will laugh to me... :( So nice plate, it was...

It looks like your PRINT_START macro is commented out in the gcode. The tool does not modify your Z offset, just feeds your start g-code then the print movements, like any slicer would. I suspect that either your start g-code was not entered properly, or it didn't like something about it. Can you show what you pasted in the start g-code box?
