Duet3 mini speed limits

@Polo also check that your slicer hasn't inserted any M203 commands into the GCode file you are trying to print.

M201 E10000
Just curios is the highest speed I can go ? -
If you are using PrusaSlicer, check Printer settings > Machine limits.
Make sure the limits match the capabilities of your printer and set the drop down at the top to only apply to time estimates.
Post your config.g so we can see what your firmware limits are set to.

@Polo you can in theory go much higher, but this is the reasonably safe extrusion value i have found. particularly i use the Orbiter extruder with Nema 14 motor. i would not go faster honestly.
are you not seeing any improved speeds?

Yes I did see a little improvement but nothing special. Is the m204 on my prusa slicer start gcode has to do something with it ?? what is the T1250 ?? Thanks fir your help !!

@Polo yes for sure its very likely your startup acceleration is causing the slow speed. i run my travel acceleration at T4000 on a CoreXY printer. you could try that and see if your particular printer can handle it. just lower it until satisfied.
i see you have a RatRig Vcore 500mm. I am using a Vcore 3.1 300mm. when i first got my printer the default settings from the RatRig setup guide gave me slow print speeds and motion compared to what i would see on Klipper videos. at first i was worried the Duet system or lack of a Raspberry pi was the problem, but i ultimately found proper settings. here is my config.g:

M204 T1250 ; set travel acceleration M204 T[machine_max_acceleration_travel] ; restore travel accelerationIf those lines are exactly like that in your start GCode, then the travel acceleration set by the first M204 command will be immediately overridden by the second one. So it all depends on what value you have configured for machine_max_acceleration_travel in SuperSlicer. If you can post the GCode file that you are trying to print then we will be able to see what value has been substituted there, and perhaps spot other issues.
The default printing speeds and accelerations in PrusaSlicer (from which SuperSlicer is derived) are very conservative. I had to increase them quite a lot to get good printing speeds.
-
I used this config and I can see a lot improvement thanks a lot !! Now the question is do I have to change my settings on the extruder to compensate the speed ? I have a bad layer once the machine reach the maximum speed.

You may be exceeding the maximum extrusion speed of your hotend.
