Duet 3 Output Not Working

JoergS5

@beachtec M906 are axis values, so set only one value for Z.

And E needs two values for M906. (for some of the other M settings also)

https://duet3d.dozuki.com/Wiki/Gcode#Section_M906_Set_motor_currents
"Example: If you have two motors on your Z axis, physically connected to Z and E0 stepper drivers, configured with M584 Z2:3, set M906 Z200, not M906 Z200:200"

@beachtec said in Duet 3 Output Not Working:

M584

also see
https://duet3d.dozuki.com/Wiki/Gcode#Section_M584_Set_drive_mapping

VERY IMPORTANT! Assigning a drive using M584 does not remove its old assignment. Therefore, if you assign a drive that defaults to being an extruder drive, you should also assign the extruder drives explicitly as in the above example. Failure to do so may result in unexpected behaviour.

so do one M584 statement

@JoergS5 That is interesting because my general guidance here has been from following @dc42's awesome wordpress blog https://github.com/Duet3D/RRF-machine-config-files/blob/master/E3D_Tool_Changer/dc42-duet3-centreZero-2Titan-2Hemera/sys/config.g... here it is as a cut and paste:

@DC42 is a kind of Ninja to me and his M584 section here has 2 entries; I thought maybe the Hermera(s) (running on ILC toolboard's over the CAN bus) might need a separate one... I mean @dc42 put it in HIS config.g file. That said, I have shrunk it to one... and the problem remains...
I would LOVE to sort this!!!... and thank you all for trying to help!!!

@beachtec you confuse me with @Veti , the M584 was from him, the M906 comment was from me.
Did you change the M commands to have 2 entries for E?
Can you please repost the config how it is now? Maybe it's not moving because the endstops have a problem and are triggered from the beginning.

And I did not understand completely your first description: is it in slot 5 or 0 which is not working? Is an endstop assigned to the slot which is not working?

beachtec

@JoergS5 I am sorry for any confusion. Stepper 5 is NoOp. Steppers 3,4,5 are configured together to be the Z-axis. Motors 3,4 run and behave correctly. Swapping connectors with stepper 5, the new motor attached to stepper 5 connector does not function while the MOTOR that WAS connected to stepper 5 works fine in another position on the z-axis. I have commented out the stops (making no difference). Just trying to simplify and reduce the problem surface. I will post it in a few minutes. @JoergS5 , thank you for looking at this!!!

Phaedrux

Are you getting any error messages in the console when you try to move the motors?

https://forum.duet3d.com/topic/18011/duet-3-6hc-short-to-ground-issue

Please check if your Duet 3 may be affected by this known issue.

JoergS5

@beachtec a different thing is that the M92 for Z is wrong.
M92 Z1600 ; Steps/mm for Z - TR8*4 / 0.9 deg stepper
400 steps per rotation with M350 Z8 => 3200 steps for 4 mm => Z800 would be correct.

beachtec

@beachtec Lucky me. I have seen that error msg. My board# is WD41-412

beachtec

@JoergS5 all 1.8 degree steppers (except the Hermera of course) ...

JoergS5

@beachtec so I was fooled by the comment...

Back to your problem, I think the first step to analyze would be to isolate the problem and test stepper 5 connector as single drive configuration (for drive X eg). If this works, the 3-drive-Z can be tested. Because now it could be a defective driver, a configuration issue, a wiring issue or something else.

beachtec

@JoergS5 Fair enough... I should have probably done that before I posted! I will test a file and publish the results.

JoergS5

@beachtec you don't need a file, you can move the steppers by direct g-code commands in the "Send G-Code" field of the DWC duet web control. That's one of the advantages of Duet, the direct execution of all commands (with the exception of some config settings).
(> sorry if this bothers you, I don't know whether you are familiar with Duet).

beachtec

I wrote one anyway to try on a few different axis. Stepper 5, nothing. Other steppers work with the same settings.

beachtec

@JoergS5 I am very grateful for the help and am always learning... do not worry about bothering me at all! I am good!

beachtec

and I love that command line window!

JoergS5

@beachtec if driver 5 is defective, the common procedure is to look at the Duet 3 whether a defect is visible for warranty, so detailed images of front and back of the stepper 5 driver would be the next step. Inspections would be made by the moderators/administrators.

It's confusing that M122 shows no errors for driver 5, so I expect that the driver is not defect. Maybe a connection problem of the connector?

beachtec

I do not understand it either. I believe that if the wiring was at fault, the stepper driver would have worked when a motor known to be working well was swapped out and the power was cycled. But when I did that. The drive I motor I swapped into Drive 5 did not work and the motor formerly in drive 5... worked fine in the new location. I would MUCH rather fix it then replace it... it's a lot of time and delays... but I understand. By the way, I wanted to redo all of my connectors doing this but there was just enough to do the job in my box but I tested them and they all show good connections, and the same Impedance and coil phasing. I have only had it a few days... been waiting to work on it this weekend. Duet Driver 5 Rear.jpg Duet Driver 5.jpg

JoergS5

@beachtec you'll have to wait for the experts. Good luck!!

Phaedrux

Did you check out that link I posted? Send an email to see if you're affected by the diode problem. If so, replacement is really the only way to go.

@Phaedrux, @JoergS5, @T3P3Tony Epilogue.

Thank you for your help with this issue.

This forum is loaded with great people, support and solutions that drive a deeper understanding of your products and the creative ways they can be used.. it is straight up good reading, I always learn something and sometimes even gain a bit of humility!

I had my replacement Duet 3 sent overnight and installed it straight away... within minutes everything was working properly, even a few little issues I had with noise on drive 0 and 1, which seemed like it might just be tuning, were cleared up and the machine performed perfectly. I love drivers on this board, it is so quiet!

Anyway, thank you again for your help and support. Cheers!
