I have had miserable luck with the duet 3 scanning probe. I just purchased a can adapter board from Amazon that is engineered so much better. Surface mount components but through hole tech for USB-C and Can cables. I ran the 5VDC line from the Cartographer 3d v3 to the same 5VDC as the USB and connect the ground can L and Can H to the screw terminals on the adapter board. Then I connected the green (CanH) and white (CanL) to the 1LC and the 5VDC and ground to the 5VDC plug used for the SZP. The blue light on the cartographer is blue when proximity to the bed is close and off when moved away from the bed. I have to enter the codes in the Config, but it appears to be working.

@T3P3Tony
Thank you for verifying that. Something must have happened to the GPIO of the 6HC or Pi 5.

@lukeatkin
I created on open in the Duet GPIO 26 pin to 40 pin cable. I purchased another one from Geekpi and it will not allow the PI 5 to boot. I believe the Duet cable is wired differently than the downgrade 26 Pin to 40 pin cable. I have wired as pictured and the red light just blinks. There is only one other way to install the 40 pin and that wouldn't work either. Where might I find the original Duet 3 6HC to Pi GIPO cable.

This adapter looks at can A,B,C and FD and communicates between them. I haven't worked on this again up to this point. I was looking forward to the Duet Scanning Z probe but this is the fourth one I have purchased. The first one worked until the cable plug fell off. The second the input shaping loosed a screw and damaged the probe board. The third and fourth where DOA. So, I plan to pick this up again. If I can detect the voltage change as the cartographer sees the bed and lights blue. Then pulling away the light goes off. If I can, I will write the codes into the config. I will also see if this Can FD capable board will communicate through can.

I have been using the Duet 3 scanning z probe and the third one has an internal short. I pugged in the board to the SZP per documentation and no LED lights and didn't show up in the web control. What I did notice was the temp on the hot end probe was now 2000C. I shut the Voron down and unplugged the Z probe board. I then booted it back up and the hot end was 22.8 and active. I checked the red 3.27vdc and black ground. The plug to the probe is black, red 3.3VDC, black Can low and red can High. I am using the supplied wires from the Duet 3 1LC, The other probes were working well this one hasn't worked at all. I have contacted Fila Studer and they asked me to enter it into the forum. Attached is a picture of the setup that was working.

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.
