Can you also send M115 to report the firmware version? It appears you're using a quite old version.

b3nitro

@phaedrux

Here it is

M115
FIRMWARE_NAME: RepRapFirmware for Duet Ethernet FIRMWARE_VERSION: Fusionware 1.18.1 RC2 ELECTRONICS: Duet Ethernet 1.0 FIRMWARE_DATE: 2017-05-15

Phaedrux

Yes that's quite ancient. However, I don't think that's the issue at hand.

There must be an electrical issue. Do you happen to have a normal endstop switch you could connect to the same port to test with?

As I'm not at all familiar with the Fusion printers am at a bit of a loss. Do they have support options as well?

b3nitro

@phaedrux

There is no normal endstop, the bed stop about 1cm before the nozzle, slow down until it toutches to calculate z-height

I'm on support with them, they say its the wiring harness or the pull up resistor BUT the wiring harness loop got conductivity and the pullup resistors are giving me 10k and 2.2k so I doubt its the issue.. I feel its the board

Phaedrux

Which connector on the board are you using?

b3nitro

@phaedrux

The one labelled "probe"

b3nitro

@Phaedrux

Got a little of success here, if I bypass the whole loop with a jumper wire while probing, the board get the connection and is going to the next step

That means the issue is in the wiring between 3.3v out of the board "probe" port after the pullup resistor AND before board probe input

Must be something with heat or vibration as the loop was "good" with ohmeter

Thanks for your help, I'll keep you posted

b3nitro

@Phaedrux

Looks like the thermistor is the culprit even while its still working

Noticed I had 3.003v at the board but 3.297 at nozzle to bed, figured out I must have voltage leakout somewhere, unplugged heater didnt change, unplugged thermistor triggered heater fault but voltage dropped to 3.003v as the board output

Ran a bed leveling without thermistor and its working!

Need to find out what type of sensor they use to change it!

b3nitro

Done deal, swapped the thermistor and everything works flawlessly now!
