      Yes that's correct. The new thing I'm getting with 3.4 firmware is an M307 error "heater 1 not found" in addition to the spi reset error. This is what the system reports in DWC after the board resets:

      3/7/2022, 7:49:00 PM Error: M307: Heater 1 not found
      3/7/2022, 7:49:00 PM Warning: SPI connection has been reset

      I hope I got my point across in the last one, but the print ran successfully with the X-axis stepper unplugged. So the entire system ran happily for over an hour without the X-axis stepper running. I'll try using a shielded cable to run the signal to that stepper and see if that helps. I may also need to ground the suspended X-axis and belt system as this could potentially be generating problems?

        Can you post your config.g and config-override.g? And the results of sending M98 P"config.g"?

          config (1).g

          running M98:

          3/9/2022, 8:56:02 PM M98 P"config.g"
          3/9/2022, 8:56:02 PM Warning: M307: Heater 1 predicted maximum temperature at full power is 678°C

          I don't have a config-override at the moment actually, that's strange.

            You have M307 H1 for both heaters.

            I suggest you delete both of those M307 lines and then retune the heaters. This time use M500 to save the results to config-override.g and then add M501 to the end of config.g to load those settings at startup.

                Has that made any difference to the errors you're getting?

                M307 H0 R0.130 K0.150:0.000 D10.00 E1.35 S1.00 B1
                M307 H1 R1.374 K0.164:0.000 D8.22 E1.35 S1.00 B0 V23.8

                Also, can you share the logs from the SBC after an error has occurred?

                access the service logs from this particular unit by running journalctl -u duetcontrolserver -e. This will output the latest logs

                  I ran a print and it went for about 15 minutes before faulting out, here's the log:

                      yes here it is, had to login to the pi and send this. It looks like there is a line about the spi connection right before the system spits out some info about the heaters. Maybe that is a result of the config override having M307 code in it and its just reporting some info on the H0 and H1 heaters. The other interesting thing is that I didn't add or tune H0. H0 is so that I can have a thermistor on the bed which is an AC heater. I just create the channel so I can monitor it. At the moment I just let it heat to max temperature (around 45C) without any PWM or bang-bang control going to the SSR.

                        Can you perform this loop back test?

                          herer are the results from running the 3 script line. only difference I see is the SPI mode, is that something that should be fixed?

                            @michaelr123 said in Duet 3 fails to start print:

                            spi mode: 4

                            I'm not sure. I'll have to check.

                            Do you happen to have another Pi to test with?

                              I have a raspberry Pi 4 that I've tried with this system before and had the same issue as before unfortunately.

                              I can run the same check and see what it says though,

                                The other thing I would try is a fresh download and image of DuetPi.

                                  So here's what I've done so far:

                                  -Fresh install of duetPi on my raspberry PI 4, re-ran RRF configurator with the latest settings to get a clean config file set going.
                                  -shielded cable install on X-axis stepper driver and for Z-probe
                                  -moved x-axis stepper driver to output 0.4 to see if it was something up with the 0.0 drive

                                  Here's where I'm at:

                                  I think I still am seeing the issue, but now I've seen it happen in an additional instance, I used the thermostatic cooler option for my coldside fan on my hemera which I kind of like, but then I accidently turned this on when I meant to turn on the part cooling fan, and this instantly gave me the same error that I've seen before, but for a different reason now. The M122 is listed below.

                                  Other thought I had, is there any chance my ribbon cable is bad? Would that being faulty cause this type of issue?

                                  M122

                                      Was the loop back test the same result with the new Pi?

                                      The ribbon could be bad, but would be unusual. You could make a small jumper cable harness to test instead of the ribbon cable.

                                      Can you post some photos of your setup? Are there cables running close together in a drag chain or bundle?

                                        here are the results from the SPI test on the PI 4:

                                        spi mode: 4
                                        bits per word: 8
                                        max speed: 500000 Hz (500 KHz)

                                        All the cables are pretty tightly fitted in a drag chain, as they were before, but here are pictures of the setup:

                                          I followed this a bit deeper and went to Danal's original SPI test tool and ran the full test with the two jumper cables. My results came back identical to his except for SPI mode being 0x4 instead of 0x0. I'm not sure if that's making a difference or not, but the test tool reports my PI is all good to go?

                                            How long is your ribbon cable? Is that the one that came with the board? Do you have another to test with or are you able to make up a jumper set?

                                            This shows which pins are actually required.
