Who here is using Duet/RRF on their printers?
I switched my ReArm from Marlin 2.0 to the LPC port of RRF2.03Beta2.
@Oliver Seiler, I see your configs on github- how current are they?
I think some of my extrusion issued might be mistakes in my config.
Sorry - only saw this now. I thought I’d get notified on new topics but didn’t and hadn’t checked in for a while.
My config hasn’t changed much, bar a few minor tweaks. I’d have to run a comparison, but the basics will still be the same.
Anything specific you’re looking for?
Thanks for following up!
What version of RRF are you using? I am on 2.04.
Speeds and Accelerations and Jerk are what I have been trying to tune.
The delta guys numbers are too aggressive, the CoreXY guys are better, but again too fast for my liking.
Here is my summary - I am posting from DWC instead of the params as it might be more readable.
; SPEEDS
; SPEED CHANGES
; M566 Xn Yn Zn En Pn where Pn is the jerk policy, currently not set in config, consider using
; M566 X900.00 Y900.00 Z12.00 E120.00 ; set maximum instantaneous speed changes (mm/min) DEFAULT CONFIG
M566 X500.00 Y500.00 Z60.00 E120.00 ; Set maximum instantaneous speed changes (mm/min) jerk seemed kinda high
; MAX SPEEDS
; M203 X9000.00 Y9000.00 Z1200.00 E1200.00 ; set maximum speeds (mm/min) DEFAULT CONFIG
M203 X9000.00 Y9000.00 Z1200.00 E3600 ; Reduced E? Set maximum speeds (mm/min)
; M203 X6000.00 Y6000.00 Z1200.00 E3600 ; Reduced speeds, maximum speeds (mm/min)
;ACCELERATIONS
; M201 X500.00 Y500.00 Z20.00 E250.00 ; set accelerations (mm/s^2) DEFAULT CONFIG
M201 X500.00 Y500.00 Z30.00 E250.00 ; Set accelerations (mm/s^2)
; M201 X1000.00 Y1000.00 Z180.00 E1000 ; from Wes
; M201 X600.00 Y600.00 Z90.00 E1000 ; from Noman
See here. I’m not pushing for max speed, but have been using these for quite some time without changes. Extruder 1 is a Bondtech QR, Extruder 2 Titan. I’m using bigger motors with a 2:1 ration, cause I earlier had some issues on Smoothie, but since I’ve moved to the Duet it’s got much better.
I’m still on 2.02
Happy to DM you my full config file if you want.
