How to change Z height in firmware?
Hi there
Noob here, first post
I have replaced the trapezoidal nut on my MK3 using this adapter https://www.thingiverse.com/thing:2390436 , this changed the maximum Z height. I've try to use Z calibration and XYZ calibration to fix it but apparently it doesn't work.
A quick google search told me I need to adjust the Z height in the firmware, but I don't know where is the parameter. https://github.com/prusa3d/Prusa-Firmware/releases/tag/v3.5.2
Could anyone help me find where that parameter is located in the firmware using Arduino IDE? And are there any other parameters I need to change as well?
Cheers
Edit: Another question, will I still be able to use Z calibration after changing the firmware?

First layer calibration should work for you, you find it under Settings I believe.
Also when you print, you can alway Live Adjust the Z height which is then also saved for future printing.
Check it out, it should be relatively straightforward.

Thanks for the replay, although running a first layer calibration will the level the bed, the printer still display a error message "Calibration failed, check the axis and run again" when I try to run Z or XYZ calibration. Do you have any ways to get around this problem?

I think the real question that should be asked is why did you use this adapter?

It would have been far better to design modified X-Ends to take the new trapezoidal nuts directly. Such a design is in my to do queue as I have a pair of brass replacements sitting on my desk waiting to be fitted as my plastic ones show slight signs of wear.

I'm using it because the holes on the brass trapezoidal nuts are closer to the center compare to the stock plastic nut.
