can't go past 13mm/s
-
I'm trying to figure out why the max speed is 13mm/s and I have the speed in the slicer set to 25mm/s. I checked and made sure the extruder instantaneous speed isn't too low. what's limiting the speed. Using duet 3, cartesian printer, 0.9 motors, lead screws. I had the microsteps at 16x but tried 4x because I thought it might help with the speed.

Do you happen to be using Cura? Check your start gcode for any speed limits being set.
-
Also check the gcode your are printing with and make sure it is even trying to command a speed higher than 13 mm/s
There are a number of things on the slicer side that can cap the max speed, like minimum layer time.

There's a typo in the drive-mapping. Maybe not....? Sorry

On setups with expansion boards the leading digit refers to the board. So 0.1 would be driver 1 on board 0, ie, the mainboard. 1.2 would be driver 2 on the first expansion board.
In setups with only a single board the leading 0 can be left off entirely as it's implied by the firmware.
Though I'm not sure what happens when mixing and matching, so might be a good idea to try cleaning that up.

I have two motors running on the z and y axis. I think your referring to the E20.0? The suggested can address for the tool board is to start at 20 and thats why im using E20.0. If i missed something you said or misinterpreted please let me know. I dont have an expansion board yet but will in the future.
-
E20.0 is fine if your tool board address is 20.
What I was referring to for maybe cleaning up is that you have no board address for Y and Z, but like I said, that shouldn't really matter.

ok so the issue I found was that cura had a setting for initial layer speed at 12.5mm/s. After raising the speed to 25mm/s I was able to fix the problem. From what I have read is that slower speeds for the initial layer are best for adhesion. That makes sense but I now can print at 30mm/s and its still adheres to the bed. thanks for the help i assumed it had something to do with the acceleration and jerk but that was incorrect.

@Phaedrux ok should i change it to M584 X0.1 Y0.0:4 Z0.2:3 E20.0

More like

@Phaedrux awesome! figuring out the correct way to write the code is what i'm trying to learn. thanks.
