Zesty Nimble config?

@eddygarra we can't see a M350 in your settings either.. here are my relevant settings:

[[language]]
M350 X16 Y16 E16 I1    			; Set 16x microstepping with interpolation
M92 X200 Y200 Z200 				; Set axis steps/mm http://prusaprinters.org/calculator/#stepspermmbelt
M906 X950 Y950 Z950 E500:500	; Set motor currents (mA); set each extruder explicitly
M906 I100			; Set motor idle factor to 100% while testing so they don't idle at all
M201 X1000 Y1000 Z1000 E120		; Accelerations (mm/s^2) Set all E-motors the same
M203 X5000 Y5000 Z5000 E1000	; Maximum speeds (mm/min) Set all E-motors the same
M566 X500 Y500 Z500 E1			; Maximum instant speed changes mm/minute. Set all E-motors the same
M92 E2400:2400			      ; Set extruder steps per mm explicitly for all the extruders

I think the M350 default's to those settings which is why I didnt point it out

Alternate problem might be that the stepper is rotating too slowly to show. It needs to rotate at a nice pace.

Zesty_Lykle

After quite some investigations it turns out that the stepper can only rotate very very slowly.
Despite the fact that the config is correct in this matter.

What could be the cause of a stepper only being able to rotate so slow? Even when running free?
Could this be a wiring issue?

What are the specifications of the stepper motor?

Zesty_Lykle

Extruding at 5 mm/sec the normal revs for the stepper should be around 260 RPM.

Zesty_Lykle

I will ask what stepper it is.
But time difference means it will be tomorrow before I have an answer.

I have Wantai motors (42BYGHW811P1), 1.8° with a rated current of 2.5a does that help?

What do you have the extruder motor current set to in the M906 command? 2000 to 2200mA should be about right. If you exceed 2000mA, cool the Duet with a fan.

I have it set too 500mA as recommended by the nimble setup page

All is resolved and the printer is printing fine now.
Ed and Brian worked together and figured it out. Reflashed the Duet and now it is printing at normal speeds.

Nice to see 3 continents working together to make things work.
