The different B values where the key. I tried the probe on temp1 and it worked. The hot end tool board was 23,6°C which is now controllable. I checked the pin connectors and plugged it into Temp0 and after booting it up it works their as well. B values affect the reported temperature.

I have tried different configurations of 308 in relation to B and C values and nothing changes, the Tool temperature is reporting 2000C, My current 308 command is: M308 S1 P"121.temp0" Y"thermistor" T10000 B4725 C7.06e-8 ;

Everything else on the tool board is working but the nozzle will not heat until the temperature probe reads correctly.
I have changed the B and C values and nothing changes it is always 20000C.

The original probe was faulty and reported 2000C and -273 or disconnected. This is a brand new probe from Revo.

This is all mounted on a Voron 2.4 R2 with the Duet 3 6HC with Duet 3 1LC and Duet 3 SZP. I am at the end of my rope and thinking about scrapping all of it for a different printer.

The SZP show up in the Duet Web control, and communication looks great, the problem is with M308 is says S10 is not a valid sensor pin.

I have the X on drive 0 , Y on drive 1, Z FR on drive 2, Z RR on drive 3 and Z RL on drive 4 and z FL on drive 5. When I home the X and Y work but the Z front left and the Z rear left go up while Z rear left and Z on front right go done binding the gantry. All Kysan Ocean motors are left to right (Red, Green, Yellow, Blue) and the are all paired the same. Do I need to re-wire rear right and front left motors or am I missing something. The printer is a Voron 2.4 R2.

Re: [Duet 3 6HC + Scanning Z Probe](not connecting)
Using the Duet 3 1LC tool board and scanning Z probe, I think the board is DOA. I get no LED light. I verified I am getting 4.99VDC at the SZP board, I also verified the CanH and CanL which are black and red wires. The tool board is working to control nozzle temp, extruder motor, hear break fan, filament fan and a BTT smart filament sensor. The SZP led is bad or the board is bad.
