@geneb this may be one of those odd occasions when downloading the firmware afresh (same version) and reflashing the Duet helps.

I tried reloading Duet2CombinedFirmware.bin again and while the flash process went without issue, the problem remains.

Fingers crossed that dc42 has some insight.

tnx.

Are you sure the endstop stopped working exactly along with the update to RRF3? And you're 100% sure it's not wiring/crimp/switch?

You could go back to 2.05.1 if you have your old config and see if it magically starts working again.

Upload the 2.05.1 zip file to the system tab along with your old config.g

I noticed the issue after the update. I've already stated that the machine had been unused for quite some time prior to the update.

Same issue - X end stop LED remains unlit. No response seen when opening the switch, either vie LED or via M119.

If you disconnect the X endstop and use a jumper wire to connect the two outer pins of the X endstop connector together (taking care not to touch the centre pin), does the LED light?

No.

In that case, I suspect that either the endstop LED or its series resistor has gone open circuit, or is not properly soldered to the PCB.

You could try enabling the internal pullup, although this would reduce the noise margin:

M574 X2 S1 P"^xstop" ; configure active-high endstop for high end on X via pin xstop

Note the extra ^ character.

That's one of the first things I'd tried when trying to work out if I had a configuration error. The behavior didn't change.

Is there a repair service for these, or should I just order a replacement?

tnx.

Depends where you are located.

https://forum.duet3d.com/topic/13875/community-repairs?_=1623423266311

If you're not near any of the ones listed there or not in the UK you might be able to find a local electronics repair or cell phone/laptop repair shop.

Or you could use one of the other endstop pins on the expansion header.

So that would be, "no".

What part of "I don't want a work-around" is unclear? Stuffing a wire into the expansion header cures the symptom and not the problem. It also prevents future use of the expansion header.

I'll just replace the board.

You're welcome for the helpful suggestion by the way.
