M98 P"config.g" doesn't produce any errors

I have a 1LC board with an endstop soldered onto IO_3 , which has been working fine for quite a long time now. Today, it has suddenly decided that it doesn't want to work and I am getting this error on trying to home:

G28

Error: in file macro line 7: G1: Failed to enable endstops

I have the endstops plugin installed and the switch doesn't register at all, I've also tried using a jumper wire to connet the ground to IO_3 and still no luck in getting it to trigger the endstop plugin. The 1LC is functioning just fine other than that, the hotend works, extruder is driven, fans spin, temp sensors sense, filament is detected.

Any ideas on things I could try?

I noticed the differing firmware between the 6HC and 3HC and just updated it, no change to the problem though:

M115 B1
Duet EXP3HC rev 1.01 or earlier firmware version 3.4.4 (2022-10-14 11:45:56)

I have my 6hc connected to a 3HC (CAN-1) and then on to a 1LC (CAN-121) . The 1LC is a new addition and I have soldered the terminator pads and a microswitch to the board, and removed the terminator jumpers form the 3HC. When I was testing yesterday it worked fine and the switch was triggering and the sync lights were working on all boards. So, I broke it down, attached it to the printer and fired it back up but this time I have a fast flashing sync light on the 1LC and the 3HC is syncing and working fine. I've checked continuity on the CAN cable to the 1LC, replaced the cable, unplugged everything from the 1LC, and tried connecting directly to the 6HC but I am still getting a fast flashing sync LED.
I don't have a very solid understanding of the wiring for CAN but I have definitely got CAN_L to CAN_L and CAN_H to CAN_H, I've reached the end of my ability with troubleshooting this one and hoping for a bit of help

@phaedrux I just did that, 24v through my normal power supply and 5v through a USB charger connectyed to the same circuit. Power supply is now fried and blows the house fuse when plugged in. Today is going from bad to worse!

@chrishamm OMG, it does! Everything lights up and the paneldue even powers on.

I've checked the voltage to the VIN and there is 24v going into it, so I didn't blow a fure in the power supply or anything, sadly

As the title says, I wired the VIN backwards on a Duet 3 6HC. The fuse didn't blow, and now I've wired everything up the righr way I've got nothing at all, no lights, no evidence of any power at all. Is there anytyhing I can do? I'm devastated by my own stupidity!

Just wondering if there are any plans to support this? It's not listed in the dictionary and I couldn't see it in the not implomented page.

I used this previously on a ramps boarb and it was incredibly useful
