@dc42 Australia. My guess is shipping alone would be more expensive than a new board.

@dc42 Thanks for the information. I'm guessing that's what happened then. Good to know for the future, hopefully that will make me more careful.

Thanks all.

I can't see any obvious damage, no discoloration that I can see.

Definitely wired the motor wrong (don't ask me why, I don't know ). The motor cable I made goes (toolboard side -> motor side):

red (B-) -> green (A-)
black (B+) -> black (A+)
yellow (A-) -> red (B-)
white (A+) -> blue (B+)

I didn't double check the motor wiring before powering on, because I was also sure that if I did it wrong, it shouldn't destroy anything. From this wiring, I assume it might just go backwards. Can't see how this would have shorted anything.

The CAN cable I made is straight through (checked with multimeter). ie yellow = yellow, red = red etc.

As I said, this was working, then I disconnected it, made the new motor wire, CAN and power cables, and connected it back up, to find it not working. So I'm stumped.

Could it have been static damage?

@o_lampe I'm 99% sure this is my own stupid fault, and therefore not covered under warranty, but holding out hope that it might be something easy to fix. But I doubt it. Just wanted a second opinion.

Pretty sure it was something to do with the motor cable I made (hemera -> toolboard). I had a second look at my other tool, and although I matched the colors, the pins locations don't match, so I think that must have been it.

Hi All,

My Config:

Mainboard: 6HC
Toolboards x2: 1LC with tool distribution board
Printer: Jubilee (core xy with toolchanger)
Firmware: 3.3beta2
Extruders: Hemera

My problem:

One of my toolboards is dead I think. When I power it on with nothing else connected and it not attached to the hemera, it gets the two solid red and blue leds, but no flashing red LED. The atmel chip gets very hot and there is a soft buzzing noise. Measured some continuity to check for a short, and get continuity between GND and 5V when not powered on. My guess is I shorted something.

The other toolboard is fine, and this toolboard was working a few days ago with the new firmware. I think I may have damaged something during the rewiring that I was doing.

Troubleshooting performed:
Tried to do a reset using the button, but got no response. Disconnected all heaters, fans temp sensor. Removed from hemera to rule out a short.

Please let me know if there is anything else I can try. Also, not sure if this a warranty issue if it turns out it is dead.

Regards
Jono

I'm getting the same intermittent freezing. Also seems to happen during toolchange procedure. Sometimes before toolchange, sometimes after.
