Duet mini 5 lulzbot won’t drive extruder

vise versa

Meaning you can hook up a different motor to that driver and it works?

How are you commanding extrusion?

anthonym

@Phaedrux correct and I can hook the motor to another driver and it works fine , Just whatever driver is E wont work I can switch e to driver 1 and wont work , I can run z2 on driver 4 no problem.

anthonym

@Phaedrux the motor will turn outside but has no torque can stop it by hand.

droftarts

@anthonym for all of these commands, remove the second E parameter:


M350 X16 Y16 Z16 E16:16 I1 ; configure microstepping with interpolation
M92 X80.00 Y80.00 Z80.00 E80:80.00 ; set steps per mm
M566 X900.00 Y900.00 Z60.00 E120.00:60.00 ; set maximum instantaneous speed changes (mm/min)
M203 X6000.00 Y6000.00 Z200.00 E1200.00:200.00 ; set maximum speeds (mm/min)
M201 X500.00 Y500.00 Z100.00 E250.00:100.00 ; set accelerations (mm/s^2)
M906 X1300 Y1300 Z1300 E1350:1300 I30 ; set motor currents (mA) and motor idle factor in per cent

@droftarts still does the same thing. I have another stepper I also tried and same thing. if I move over to the x driver it works. Same basically it wont drive e.

Is this what you changed it to? Try this

M350 X16 Y16 Z16 E16 I1 ; configure microstepping with interpolation
M92 X80.00 Y80.00 Z80.00 E80 ; set steps per mm
M566 X900.00 Y900.00 Z60.00 E120.00 ; set maximum instantaneous speed changes (mm/min)

Also send M98 P"config.g" in the gcode console and copy and paste any error messages here.

anthonym

@Phaedrux Yes

Error: in file macro line 27: M566: array too long, max length = 1

anthonym

@anthonym Error: in file macro line 26: M92: array too long, max length = 1

Phaedrux

Did you use the block from me above?

anthonym

@Phaedrux Yes that seems to have fixed it !!

FYI these errors were because you didn’t remove the second E parameter.

M92 X80 Y80 Z80 E420:80 ; set steps per mm
M566 X900 Y900 Z150 E420:150 ; set maximum instantaneous speed changes (mm/min)

You also left the colons : in after the first E parameter value, which may not have helped. And the motor had no torque as you had set it to 150mA:

M906 X1300 Y1300 Z1300 E150: I30 ; set motor currents (mA) and motor idle factor in per cent

@droftarts Its seem to be working , I see that now thank you for explaining I really appreciate the help.

anthonym

so the issue I am having now it’s extruding way too much if I ask for 10mm I get over 100 my steps per mm are 420 on the aero 2.85 mm with a .5 nozzle.

T3P3Tony

@anthonym send M92 and M350 from the command line and see what they report.

anthonym

@T3P3Tony I will as soon as I get home and post the report. Thank you

Phaedrux

Is your motor a 0.9 degree or 1.8 degree?

T3P3Tony

@anthony1m and you are definitely getting 10x the requested extrusion? Please measure the actual amount extruded when you send G1 E10
