@t3p3tony Yep all other steppers moved fine - did what @o_lampe told and now problem is gone

@phaedrux
I was running at F12000, used those speeds on my a mk3 with E3D 48mm steppers, guess the orginal prusa steppers dont like those speeds, when i drop to F8000 errors are gone.

Do you know if its because the steppers are missing steps ill get those errors?

Hey - Got an older prusa mk2.5s with a duet 2 wifi, it have been running fine for months, but now when im doing G32 ill get "Warning: Driver 0 warning: phase a may be disconnected, phase B may be disconnected"
Driver 0 is my X axis and its running fine. I have checked all wires and connector all seems fine, not sure what else to look for?

@gixxerfast Looks like i had a brain fart! got a pt1000 so just stole your config - old one worked tho

@t3p3tony Yep all other steppers moved fine - did what @o_lampe told and now problem is gone

@o_lampe Thats all i needed - Thanks!

@o_lampe Have tried upping the amps but no difference - have checked the nozzle and tried replacing, can manuel push the filament through the nozzle with little to no force, when gears are not engaged.
Im sure its not a hardware problem, but some where its not loading the config.g right on start up - when i do M98 pconfig.g all problems are gone

@t3p3tony Yep its skipping steps. looks to me like its not the getting the right amount of current..
I got a bondtech prusa i3 mk3 extruder
STEPPER MOTOR
Lightweight 25 mm pancake stepper with 18 N/m torque.
Max Input Current : 0.8A
Max chamber working temperature : 80℃

Just got into duet and reprap few days ago and im having trouble with low torque on my extruder stepper. if i go to console and use m98 pconfig.g the extruder is working like it should. what am i missing?
