Pause at Layer or Height for Cura 3

thingiverse

I'm using this script for pausing at a specific layer number or height in Cura 3.2. I want it to be fast and easy to use without thinking about offsets or making calculations based on initial layer height and normal layer height. Just input the layer number where the pause should occur, such as the layer with color changes or the layer printing the roof over a nut that will be inserted into the print. M0 is used, so a simple click on the knob is needed to continue printing. The script has an option to compensate for Z backlash because my printer creates a neck in the part where the pause occurs. The head moves below the paused layer by the indicated amount, so make sure to park the head away from the print to avoid collision. Retraction is used if it's enabled in Cura first extruder settings. The retraction amount is also read from these settings. The extrude amount compensates for oozing during the pause. This script goes into the folder: C:\Program Files\Ultimaker Cura 3.2\plugins\PostProcessingPlugin\scripts Tested on HK Fabrikator with Marlin 1.1.8. The test M322 version has a switch for M0 and M25, but it's not tested with M322 which is supposed to work with FlashForge Creator printers.
