1LC Driver 0 not responding

Gamefanatic3D

I am standing up a Duet3 Mini 5+ and 3 x 1LC (v1.3) boards that are connected to Obriter 2.0 extruders.

I'm banging my head against the printer trying to figure out what I am missing here.

I am unable to get the Orbiter motor to engage when connected to the 1LC. If I connect the motor to an open driver on the Duet (driver 0.4) I can get it to engage.

I am running the following Macro to test the motor operations:

M302 P1
T0 P0

echo "Begin Move"
G1 E100 F100
echo "End Move"

T-1 P0
M302 P0

When doing this with the motor connected to (0.4) on the Mini I see the motor turn. However, when I put the motor back to the 1LC (21.0) and execute the macro above I see the system show "Busy" in the web browser, but the motor never turns.

I've tried unplugging the motor and getting the same effect, the system never tells me any errors or wiring problems when on (21.0), but when on (0.4) it returns the expected error:

Warning: Driver 0.4 warning: phase A may be disconnected, phase B may be disconnected

I attempted to probe the B- & B+ / A- & A+ terminals after executing the Macro above on while connected to (21.0) I see no voltage. When I perform the same test with the motor connected to (0.4) I can see voltage.

I don't have everything configured on the 1LC, but so far I have validated all the other components are working so I know that the board is still good (same issue across 3 x 1LC's so far).

Any suggestions on what I can do to get some feedback from the 1LC as to why it's not working?

Below is the diagnostics right after attempting a move while the motor is connected to (21.0)

I was running v3.5.4, but upgraded to 3.6.1 rc1 last night in an attempt to see if maybe it was just a bug, but no change.

@Gamefanatic3D
Okay, so I went through and tested each 1LC board without them all connected at the same time. It appears the issue is only with the (21.0) board. The other boards (22.0, 23.0) all work to include (20.0) which is running the tool head.

I believe this may be an issue with the single board. Does this sound like a hardware issue?

I'll swap out this board soon to validate my assumption.

@Gamefanatic3D
Okay so I'm certain the driver is blown by the look in this picture.

Swapped out the board, and now to the next problem I'm sure I will have!

I knew I'd figure it out once I asked for help!

droftarts

@Gamefanatic3D Yes, that's definitely blown! Any reason you can see for it? Short circuited motor wiring, or shorted out on something it was mounted to? If you can take a good picture of each side of the board and post it hear, I can check for any manufacturing faults. Is the board new? If so, when and where did you purchase it from?

There is a sticker right under that driver.

This was a brand new board, but puchased in August 2024. I believe this might have been my fault. When creating my initial power cable to the Tool Distribution board about a month ago and got the PINs reversed in the circuit layout. I immediately powered off and reversed things at one end and plugged it in and didn't notice any issues. At least not until now...

None of the other boards had this issue since I had updated the build guide for those circuits.
