A-Better-End-Print-Macro

This was loosly based off of the idea from jontek2's A better Print Start Macro

Please note: julianschill's Klipper LED effects are also listed within this macro. They have been commented out by default. If you have LEDs installed, and the plugin installed, feel free to uncomment them.

In addition to this, I had included delayed gcodes for a nevermore to remain running (if installed) for 5 mins to help scrub the air. As well as included a delayed gcode for LED status to update after 5 min to reflect the printer part status. These have been commented out by default to avoid any errors for someone that does not have these installed. If you do have a nevermore, or LEDs, installed please feel free to uncomment these options.

The idea behind this end print macro:

• have the printer detect is maximum z boundries
• apply a percentage threashold for the Z axis to raise to if the Z axis gets with 20% of the maximum heigh threshold.
• if z reached the 20% boundry, limits the z lift at end of the print and also then lowers the toolhead 10mm so next unknown home doesn't slam into top of Z

The End Print macro should work for all styles of printers (cartesian, corexz, corexy, delta, ect).

⚠️ Required changes in your slicer ⚠️

You need to replace your "End G-code" in your slicer to be able to send data from slicer to this macro. Click on the slicer you use below and read the instructions.

SuperSlicer

In Superslicer go to "Printer settings" -> "Custom g-code" -> "End G-code" and update it to:

END_PRINT

OrcaSlicer

In OrcaSlicer go to "Printer settings" -> "Machine End G-code" and update it to:

END_PRINT

PrusaSlicer

In PrusaSlicer go to "Printer settings" -> "Custom g-code" -> "End G-code" and update it to:

END_PRINT

Cura

In Cura go to "Settings" -> "Printer" -> "Manage printers" -> "Machine settings" -> "End G-code" and update it to:

END_PRINT

END_PRINT Macro
