Axes motors move slower when combined with extruder motor

[Ravs99]

Hey all. Im working on making a hangprinter. I have been experiencing an issue with motor movements. If i send a g1 xyz f4000, it moves the way it is supposed to but if i want to move the extruder motor as well when i type g1 xyz e f4000, the XYZ motors moves drastically slower. My axes motors are NEMA23s and extruder motor is a geared nema17. Currently of RRF3.3 on a DUET3 board. Any help would be appreciated. Thanks

@ravs99 Your extruder has a lot of steps-per-millimeter.

Maybe you are hitting the maximum step rate for that axis.

For a test ONLY, try setting the steps-per-mm for your extruder to 1/10th of the current value and see if that allows the motion axis to move faster.

If that works, I don't know what to suggest. There are people who know much more than I do about this.

@ravs99 most likely the move you have requested cannot be executed at the requested feed rate without exceeding the 300mm/min maximum extrusion speed that you specified in the M203 command in config.g. So that 300mm/min is the limiting factor.
