How to diagnose an issue with broken stepper output
-
@dima If it was me id change the stepper cable out first then if that failed move the suspect driver to an axis/extruder that I can control on its own and attempt to move it.
Is there any sign of damage to the driver chip/board? does it make any noise at all when driving?
-
@jumpedwithbothfeet I already know the stepper&cable work I plugged them into another port and they worked fine. I did not see any damage on the board.
When I try to get that specific port to move (extrude), any stepper attached does not move.
-
@dima it would be helpful to post your config.g, what driver is the one at fault?
-
I wanted to ask if it could be in fact a firmware issue, and hopefully not anything physical.
this is my config, I'm aware my fans are off.

@dima
The driver is 0.5
And when I run m122 I get
'Driver 5: position 0, standstill, reads 48153, writes 0 timeouts 0, SG min/max not available' -
@dima you need to run through and change each of these -

The first parameter specified will be used for all motors on the axis. You should use identical motors on any axis that has more than one motor to avoid unexpected behaviour. Example: If you have two motors on your Z axis, physically connected to Z and E0 stepper drivers, configured with M584 Z2:3, set M566 Z50, not M566 Z50:50https://duet3d.dozuki.com/Wiki/Gcode use this to check each M code and change them as required

Can you send M122 and M98 P"config.g" and post the result?
How many extruders do you have? 1 or 2?
What axis are you trying to use drive 0.5 as? Right now it's set as extruder 2. How are you trying to move the motor?
-
@phaedrux
when I run m122 I get
Driver 5: position 0, standstill, reads 48153, writes 0 timeouts 0, SG min/max not available
I have 2 extruders, 0.5 is the second extruder.
Sidenote - I cannot see a second extrusion control when I go the dashboard tab of dwc.
If that is at all helpful -
@dima when I try to extrude from it, I get
response took to longissues raised -
@phaedrux said in How to diagnose an issue with broken stepper output:
M98 P"config.g"
M98 returns ->

Error: unknown pin name 'fan0'
Error: Fan number 0 not found
Error: unknown pin name 'fan1'
Error: Fan number 1 not found
Also just noticed in consol!
Warning: motor phase A may be disconnected reported by driver(s) 5
and
Warning: motor phase B may be disconnected reported by driver(s) 5 -
Can you post the full M122 result from the console tab please?
motor phase disconnected can mean exactly that and the wiring it not actually connected to the right phases.
Are you able to test that same wiring and motor on another driver successfully?

@phaedrux
I have successfully used the stepper motor (w/ the same wiring) from different ports

When and where did you purchase your Duet?
-
@phaedrux I bought the duett board with a 3d printer (used) off FB Marketplace. I bought it last summer (2021), I do not know how long ago the previous owner had the board.
-
Ah, that does complicate things on the warranty front as we don't know the vendor, it's age, or even if it is genuine. If you can post some photos of the board we may be able to get a better idea of it's provenance. The 6HC is a fairly recent board and only very recently cloned, so I think the likelihood of it being genuine is good.
-
@dima if it's black it's a clone and if it's blue it's real
-
-
@Dima still doing a little digging to see if we can pin down the original purchase of the board to determine warranty status.
Barring that, there are two other options available.
We have some refurbished Duet3 boards that we offer at reduced cost on exchange with the old board.
Or, if that's too expensive an option, and you require all the drivers perhaps using a toolboard for the extruder would be a good option?
-
@Phaedrux
would this mean that it is not a software/firmware issue?
Could I be running too old of a firmware? -- even if its 'stable' -
No it doesn't seem like a firmware issue. The phase error would indicate there is a connection issue, but you have tested the motor and wiring successfully on a different driver. That would indicate that the driver has failed/damaged.
Though if you'd like to update to 3.3 just in case feel free.
