Help Getting Start/Stop gCode to work
Hi All,
I use to use PrusaSlicer as my main slicer when using my Ender 3pro until I upgraded my printer to using the Sonic Pad. All instructions for it were for using cura and I admit that has been working well for me, however I want to get back to using PrusaSlicer again. Th problem I am having is that I somehow deleted my Start and End gcode settings and cant seem to find where i may have saved the setup i had. I tried copying the start/stop settings i had from cura into it but i get errors so I was hoping that maybe someone could take a look at what i have and help me get my prusa start/stop settings to be similar.

This is what i get when i slice.

Thank you for your help. I am looking forward to how to make this work.
RE:
Cura and PrusaSlicer use differently named placeholders, and you'll need to do the translation from Cura placeholder names to PrusaSlicer placeholder names.
Probably the easiest way to do this is in PrusaSlicer because there is an editing mode that gives you a hierarchical list of all the placeholder names. Apparently you've done the first step of copy/paste the Cura custom g-code into the appropriate places in PrusaSlicer. Each of the text boxes for custom g-code in PrusaSlicer has an edit button. My mouse pointer is next to it in this screenshot:
This will give you a screen with two panes:
The one on the left is the hierarchical list of placeholder names and the one on the right is an editing box for the g-code. Select one and below the list will be the syntax and a description for the selected placeholder. Double-click on the placeholder name and it will be inserted into the g-code where your cursor is.
Be warned: Some placeholders are named with a completely different mindset. For example your Cura Placeholder "machine_depth" I'm guessing is the max Y of the print area, so in PrusaSlicer it would be "print_bed_max[1]". (I think you want a "1" there to mean y, I think x would be "0" (zero). You may have to experiment to be sure.) Also, you may have to choose a static value for some Cura placeholders as there may be some that don't exist in PrusaSlicer.

RE: Help Getting Start/Stop gCode to work
Maybe start from re-running Configuration Wizard and use 3rd party printer, Creality Ender 3 Pro is on the list.
