Technical defect?
-
Hello Guys. I'm new here and it's my first post.
my Duet 3d Wifi Controller board is still not working correctly or has an technical error since a few days.
When I try to home the z-axis, the z motors Lifts the Extruder as requested. But then the x and y motors have to move, but still don´t do.I controlled the x Motor separatly via the homing command and it still worked. After that I moved it the other way round and it move one round and stuck. Neither I could move it via Software nor by Hand.
I´ve tried 3 motors connected to the plugs E1, X, Y and everytime I´ve got the same issue.
In my opinion the Controller board has got an technical error or do anyone has got a solution?

@GuybrushTreepwood Lovely name, I'm a Monkey Island fan too! Though it's Threepwood!
Can you post your config.g and homeall.g file? It sounds like there is an error somewhere. Please also take a picture of your Duet so we can see how wires are connected. Finally, send M115 to the Duet and post the response. This should give us the information to help diagnose the problem.
Be aware that you should ALWAYS turn off the power to your Duet board before plugging or unplugging motors into the stepper driver pins. If you don't do this, you risk damaging the stepper driver chip. Which you may already have done.

Note that an axis will not move until homed. For testing, you can override this with

@droftarts Yes I know about the spelling, but it´s often used and so I didn´t try. And of course the importance of turning of the board, so I hope the stepper driver are intact...

@Danal so I´ve tested to override the homing. then sent g0 for x-axis. For positive values, the motor hasn´t moved and blocked immediately. With negative value, it moved once and then blocked, too.
-
by the way, the board operated correctly all the time. A day before the first fault it printed correctly. At next day I powered it on, tried to home all. the x and y axis homed correctly and when it had to move to the middle of the heat bed nothing happened
-
raise your motor currents in M906. Maybe 1500.
-
@Danal did it and nothing changed, except the motor is humming little bit louder. 1,5A is the limit for this motor I think. It´s a 42SHDC3025-24B
-
@GuybrushTreepwood
measure the resistance of the motor for each phase. if the motor is humming its recieving current. -
@Veti I´ve measured the resistance now. it starts with 5 MΩ on green, black and goes up to over 30MΩ.
the blue/red coil starts with 12MΩ and goes up to 20MΩ.
