sounds to me like a broken wire inside the insulation. When moving to this exact position the wire is bent so it does not have contact anymore. moving on to the next point it is bent another way, contacting again.
I once had this Problem in the wire to the heater cartridge on the hotend. Had to search some weeks until I noticed, because Temperature was swinging when moving. Did PID tunings, changed Fan duct, put insulation on hotend - nothing helped. One day it was broken that much, i got thermal runaway. Scratched my head some eventings until I noticed it was always on front right where there was maximum bending on the wires...

Sounds like you've had some bad experiences there. I can say that isn't the way the auto mechanics that |I choose to pay operate, but then I'm a car guy myself, and more or less rebuilt my car from the ground up.Quote

Do you work as a automobile mechanic ?
They too start by replacing the most expensive and unlikely parts (ECU, unrelated actuators, sensors...) before looking at the basics (fluid levels, fuses, connectors, wires...).

I do apply the same troubleshooting to my hobbies as I do to my car, and I don't like spending money on replacing parts if I can make an existing part do its job. My winter beater car is a bit past the line, to the point where I'm about to just give up on it entirely.

I bought 3 Andromeda boards and the universal PCB. I managed to make it work great, but it only works for a few seconds. Then it completely stops working and I have to either unplug and replug the board or turn the printer off and on again to get it working. It works instantly again after power cycle.

what Vin voltage are you feeding it?

Sorry I've been slow to reply to your email, life is very busy at the moment.
What kind of controller board are you using?
Do you have pullups enabled?
Are you able to measure the voltage of the SIG pin when the Uni board is plugged into your controller?

M558 P8 H8 F780 I1 T9000 R0.8 Z1 ; Set Z probe type to unmodulated and the dive height + speedsedit: This was from an older backup of my config. I have since edited the dive height and speed, but this works. I'm also using hte piezo as the Z endstop, as you see here.

This kind of service is why I'm happy that I paid Idris for my piezo sensors. He's been really good to me, too.
The described behavior definitely says that the Duet disables the pullup resistor for analogue monitoring. Good to know.

Very strange...
Rather than messing about with trying to work out what's going wrong, I'll send you a replacement, would you be able to return the board you have to me?
