Issues switching to Orca Slicer Profiles & Start G-Code

[westech]

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:

; Ender 3 Custom Start G-code

G92 E0 ; Reset Extruder
G28 ; Home all axes
G29
G1 Z2.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed
G1 X0.1 Y20 Z0.3 F5000.0 ; Move to start position
G1 X0.1 Y200.0 Z0.3 F1500.0 E15 ; Draw the first line
G1 X0.4 Y200.0 Z0.3 F5000.0 ; Move to side a little
G1 X0.4 Y20 Z0.3 F1500.0 E30 ; Draw the second line
G92 E0 ; Reset Extruder
G1 Z2.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed
G1 X5 Y20 Z0.3 F5000.0 ; Move over to prevent blob squish

End G-Code

G91 ;Relative positioning
M83 ;Relative extruder mode
G1 E-2 F2700 ;Retract a bit
G1 E-2 Z0.2 F2400 ;Retract and raise Z
G1 X5 Y5 F3000 ;Wipe out
G1 Z10 ;Raise Z more
G90 ;Absolute positioning;
M82 ;set extruder absolute mode
G1 X0 Y{machine_depth} ;Present print
M106 S0 ;Turn-off fan
M104 S0 ;Turn-off hotend
M140 S0 ;Turn-off bed
M84 X Y E ;Disable all steppers but Z

@westech I'm a bit confused about what you're asking.

Is it that you can't set up a printer? You can either use the "Setup Wizard" and choose "Generic RRF printer", or "Create printer" from the printer drop-down box. When setting up a new printer in Orca, I don't select a printer profile, I create a new one with the "Can't find my printer model" tickbox selected (I find this way more awkward, though, more options!).

Do you mean you can't find where to edit the start and end gcode in Cura? Click on the icon next to the printer name (in the printer drop-down box), and it will show the Printer settings. Go to the "Machine G-code" tab.

@droftarts I know where to copy my start and end Gcode into Orca. But I don't get the same heat up, bed leveling, then my purge line etc. Orca seems to go to the center deploy my BL touch then heats up. no bed mesh. I was asking in the big picture, is selecting any printer profile enough. The only thing which makes a printer profile RRF is switching Marlin to RRF? Which I know how to do. OR, are there other settings which need to be set to tell Orca it is RRF?

My bottom line, is neither the built in profiles are working for me. And if anyone who uses a similar printer have working profiles or knows were there are profiles I can DL online?

As I said, I really want to run through the Orca calibration functions.
