Motor doesn't move

Phaedrux

Sounds like a wiring issue. Possibly a bad crimp.

https://duet3d.dozuki.com/Wiki/Choosing_and_connecting_stepper_motors

Check that your motor phases are paired correctly and that the wiring is making good contact in the plug.

For motor current, aim for 60-85% of the rated max of the motor.

zfeng

@phaedrux I double checked the motor phases pairing and also the wiring is making good contact. But still the same. Is there anything wrong with the setting? Do I need to change any code?

zfeng

@phaedrux I'm using the board for an xyz three direction movement system. I connected the motors to the X-axis, Y-axis, and Z-axis connectors on the left side of the board, is this correct?

zfeng

@phaedrux Looks like I have similar problem as this one: https://forum.duet3d.com/topic/795/motors-will-budge-but-not-move. How to recompile the firmware for CoreXY?

SIam

@zfeng normally you don't have to recompile the Firmware!
What kind of Stepper Motors you are using?
Can you post your config.g file and the output of M122 (enter this in the console)

Dougal1957

does the duet think that the device has been homed or have you instigated the move anyway override (Can't remember of the top of my head what that is).

Phaedrux

Please post your config.g and homing files and the results of sending m122 and M98 P"config.g" in the console.

zfeng

@siam I am using a Duet ethernet board instead, I wired the limit switches, and the motors. Now the problem is, it shows G0/G1 insufficient axes homed when I tried to move the motor.

@siam There actually are mode code coming out of the M122, but was marked as spam by the forum so I cannot post them here...

Phaedrux

You'll need to generate a config file set for your printer here: https://configurator.reprapfirmware.org/

At the end save the zip file and then upload it to the web interface system tab.

You can't move a motor before it's been homed by default.

If you want to force motor movement to see if it's working you can send G92 X100 Y100 Z100 to trick the firmware into thinking the axis have been homed. You can then use the jog buttons to move the motors but be careful because without the proper axis dimensions and homing sequence it won't know the actual position of the print head and will gladly smash into the frame if you tell it to.

@phaedrux How to check if my printer was originally shipped with RepRapFirmware?

zfeng

@phaedrux I just checked the Filastruder website where I bought the board from, it is shipped with RepRapFirmware. Then which predefined template should I choose? Thank you!

Phaedrux

What kind of a printer do you have?

zfeng

@phaedrux I use an extruder to print. I only need to board to control the motion system, extrusion and hot end temperature. The hot bed has it's own controlling system.

Phaedrux

Maybe take a look at some of these guides to get a feel for how the configuration system works.

https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter

https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+1:+Wiring/37

zfeng

@phaedrux The frame for the movement system is a cartesian C-beam machine like this:https://openbuildspartstore.com/openbuilds-c-beam-machine/

Phaedrux

Where are you getting stuck in the config tool?

https://configurator.reprapfirmware.org/

zfeng

@phaedrux The hot end and fan use digital signal so I cannot wire them directly to the hot end and fan connecters. I think I should wire them to the expansion board instead. When I generate the config file, on the expansion boards page, it says no expansion board configured.

Another question I have is, what is the xyz movement unit in the Duet web control? I need to adjust the step size according to the screw. Thank you!
