How to configure multiple extruders that have different steps/mm
-
I want to setup a new printer with multiple extruders, but they will have different steps/mm and it seems to me like the standard configuration doesn't allow for that. How would I configure that?
Here's my config.g file so far:
; Configuration file for Duet 3 (firmware version 3.3) ; executed by the firmware on start-up ; ; generated by RepRapFirmware Configuration Tool v3.3.10 on Thu Feb 24 2022 12:35:32 GMT-0600 (Central Standard Time) ; Panel Due M575 P1 B57600 S1 ; enable panel due G4 S4 ; wait for screen to start ; General preferences G90 ; send absolute coordinates...

@p8blr for extruder axes, you simply add more to the M92 command. Eg.
M92 E420:350 ; E0 with 420 steps and E1 with 350You then need to do the same for the acceleration, max speed, jerk, current and microstepping commands.

@engikeneer Exactly what I needed. Thank you!
