I have a Neptune 3 Pro and I'm going to swap the stock board for an SKR mini E3v3. The printers already been klipper'ed but when I swap the mobo what changes will I have to make on the software side to get everything working again? Do I just need to edit the printer.cfg to update all the pins and whatnot or is there more to it?
I'm having an issue when printing multi-colour prints from OrcaSlicer. The first layer goes down fine and then the print pauses for me to change the filament. My filament change g-code in OrcaSlicer is simply "PAUSE". It pauses, I swap the filament and purge it, and when I go to resume the print. It goes to the bed, ejects this big blob and an error of "Move exceeds maximum extrusion" appears in the console.
I imagine this is something to do with relative/absolute extrusion but I'm not really sure how to go about fixing it. My extrusion is set to relative in OrcaSlicer and in my start print macro it is also set to relative. This isn't an issue if I manually insert PAUSE commands into gcode and print multi-colour that way, only when I use the integrated multi-colour settings in OrcaSlicer. Here's my RESUME and PAUSE macros for reference.

Annoyingly I dropped this camera and the LCD broke. Everything still works, just half of the screen is cracked and black so it makes it hard to use to the point where I'd rather use something else. I really like this camera and I was wondering if theres anywhere I can buy a replacement screen for it? I've looked on AliExpress + Ebay to no avail.
