faulty duet 3 mini?
-
i have just got my new duet 3 mini and wondering if i have a faulty board. i've updated it to the latest version and cabled it up and have two primary issues.
this first issue is the steppers drivers seem to be behaving strangely. as an example, if i try and home certain axis other axis will either move instead or in tandem. as an example if i try and home y, the z motors will move. if i try and home x it just clunks and stalls out. if i home z it goes up instead on down, etc. i've adjusted the x & y currents in either direction and it doesn't seem to make any difference.
everything was working perfectly fine running on a duet 2 wifi and just swapped the steppers wires as is. i understand the d3m potentially uses a different pin naming convention than the d2w, however i've seen posts that show P0.1, P0.2, etc referenced as well as P0, P1. i went ahead and ran through the configuration tool and plugged in all the correct numbers from the d2w config and loaded all the files in /sys just to make sure it was all the correct syntax.
the one main difference is i have dual z motors, and the d2w just used one driver wired together to run two (quite a nice feature, why would you change that?). i've went ahead and coupled two of the drivers together to the run z motors and of the 4 motion steppers are the only two that actually run without complete clunking and "stalling". however they are quite loud which was a surprise given these are supposed to be 2209 drivers.
the second issue is the system can't seem to reconnect to wifi on soft restart / reboot. i have to physically power off the board and turn in back on and it will connect right away.
is this potentially faulty hardware? the board i received revision v0.5. below in the config.g with the changes for the dual z motors.

This is not right, but I have no idea if it would cause any issues.
Just FYI, I'll keep looking.

@alankilian that was a typo as was marked as spam before i could correct it. it won't let me change it now that its been flagged.

@alankilian i do think there is an issue with the stops though. the d3m has a different setup and then the d2w and might need to trail and error the correct wiring combination. the end stops i have are just switches which should work the same way as the d2w but doesn't appear to be the case.

Hi,
What firmware are you running?
Your end stops are using v3 syntax.
In your config you have things like Z60.00:60.00 - that is not supported.
In M584 you have Z0.2:0.3 - that is treated as one stepper, so to speak, for commands M92, M566, M203, M201, M906.
Also you said Z was working but not X or Y. X and Y both have lower current settings than Z - try upping them.

Check your steps per mm and motor mapping. I used this format:
M584 X0:1 U1 Y2 Z3:4 V4 E5 ; set drive mapping
M92 X64.00 U64.00 Y64.00 Z1259 V1259 E420.00 ; set steps per mm

- version 3.2.2, hence the v3 syntax. (i believe the 3 mini only supports v3+)
In your config you have things like Z60.00:60.00 - that is not supported.
- can you verify that? that syntax comes from the configuration tool
In M584 you have Z0.2:0.3 - that is treated as one stepper, so to speak, for commands M92, M566, M203, M201, M906.
- correct, per my original post you will see i am running dual z-motors.
Also you said Z was working but not X or Y. X and Y both have lower current settings than Z - try upping them.
- i have up'd them, lowered them, and set them the same and i get the same results. y will move but makes a horrible noise while doing so and continues to "grind" even after hitting the end stop. x does nothing but vibrates in place. all of the steppers are the exact same model and have the same wiring.

From the docs:
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 M906 Z200, not M906 Z200:200
Can you do something so the X & Y steppers can be tested without any load on them? Loosen the pulleys perhaps?

I can't think of any way that commanding one motor should affect a different motor, unless the kinematics have been selected to do that. I suggest you do the following:
-
Run M669 without parameters to check that the correct kinematics is selected. I don't see a M669 command in your config.g file, so it should report that Cartesian kinematics is selected, with a unit diagonal matrix.
-
You can use G91 G1 H2 commands to test individual motors.
Regarding motor directions, I think you will find that on the Duet 3 Mini the directions are reversed compared to the Duet 2. This is a consequence of the TMC2209 pinout. So you will need to change the M569 commands to reverse the directions. We could change the firmware to undo the reversal, but this would inconvenience all those users who have configured their machine to work with the existing directions.

what kind of printer is it?
