Greetings!
I have 3 Ender 3 Pro, running RRF. Love it. Always used Cura. Wanted to switch to latest Orca. I haven't found a printer profile that works. If anyone is familiar with Orca (PrusaSlicer). My main goal is to retain my BL Touch G29. This is probably not a RRF issue but an issue of how Cura v. Orca uses Start and End G-code. Here are my specs and working Cura G-codes.
Ender 3 Pro
Creality Dual Gear Extruder
BL Touch
RRF Duet Firmware
Current Cura Start G-Code:
