How to diagnose an issue with broken stepper output

jumpedwithbothfeet

@dima you need to run through and change each of these -

M350 X16 Y16 Z16 E16:16 I0 ; configure microstepping without interpolation
M92 X100.00 Y105.00 Z1600.00 E110.00:110.00 ; set steps per mm
M566 X900.00 Y900.00 Z60.00 E80.00:80.00 ; set maximum instantaneous speed changes (mm/min)
M203 X6000.00 Y6000.00 Z180.00 E1200.00:1200.00 ; set maximum speeds (mm/min)
M201 X500.00 Y500.00 Z20.00 E250.00:250.00 ; set accelerations (mm/s^2)
M906 X800 Y800 Z800 E800:800 I30 ; set motor currents (mA) and motor idle factor in per cent

M566 Gcode reference
RepRapFirmware does not support individual motor settings where an axis has multiple motors connected to different stepper drivers. 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 Z50:50

https://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?

Dima.

@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.

@dima when I try to extrude from it, I get response took to long issues raised

@phaedrux said in How to diagnose an issue with broken stepper output:

M98 P"config.g"

M98 returns ->
HTTP is enabled on port 80
FTP disabled
Telnet disabled
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

Phaedrux

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?

Dima.

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

Phaedrux

When and where did you purchase your Duet?

Dima.

@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.

Phaedrux

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.

jay_s_uk

@dima if it's black it's a clone and if it's blue it's real

Dima.

@jay_s_uk @Phaedrux

Phaedrux

@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?

Dima.

@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'

Phaedrux

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.

Upload this zip file to the system tab.

Dima.

@phaedrux Is there a way to check which chip is broken, such that I could try and replace it?

Phaedrux

It's likely the driver chip itself but it's hard to tell without any obvious visible damage to point the way.

Dima.

@phaedrux ok, thank you for all the help
