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

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:

Were you able to gather this?
-
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 driveHere'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?

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?

F0 0DAll 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.
-
Its the original ribbon cable that came with the wire and connector kit.
I could make a short ribbon cable and give that a go. The little jumpers I have aren't the nicest, but they should work.
Do you have a pin map for the orientation and exactly which pin is which on the duet? I was able to find one for the pi's, but this is as much detail as I can find on the duet doc site :
-
The pin numbers are printed on the silkscreen under the board - but of course that's not possible to read after its mounted! I have updated the documentation to show the numbering:
-
Ah that makes sense, I've got the board mounted to an acrylic plate, so I could have climbed under the machine to see that, thank you though!!
-
Update:
I tried switching out the SPI cable: the printer ran fine with the somewhat sketchy ribbon cable I made. Still saw the same issue, SPI reset after a minute or so of running.
- I'm going back to the X-axis, here's where I'm at -
I left the X-axis motor plugged, wires in the wire loom, but I took the set screw out of the pulley and de-tensioned the belt, letting the motor shaft just spin freely inside the pulley:
This ran for 10 - minutes with no issues (This is my slow descent into madness, so humor me with this rabbit hole - we're going to call 10 min+ running a success, more testing will follow). This verifies that everything with the motion control to this specific electrical and mechanical system are sound, which is good.
I then reattached the pulley to the motor shaft with the pulley still de-tensioned: this also ran for 10 minutes plus. This is all with the same basic cylinder G-code I've been using for the last few weeks mind you. Again, this verifies this further verifies that its not a signal to the motor issues, cable issue, driver issue, etc.
So then I reinstalled the belt, not quite as tight as I had it before, and within 2 minutes of running, I had a partial failure, which I've never seen before [console output below]:
3/20/2022, 1:17:19 PM Connection to Duet established
3/20/2022, 1:17:19 PM Warning: Lost connection to Duet (Board is not available (no header))
3/20/2022, 1:15:50 PM M24 Printing resumedThe print kept running after this. Maybe I'm going crazy, but somehow it seems like my old belt attachment system grounded the belt, while the new one completely isolates it in plastic. 5 minutes after this weird half failure happened, the system totally reset:
3/20/2022, 1:22:42 PM Warning: SPI connection has been reset
3/20/2022, 1:22:42 PM Connection to Duet established
3/20/2022, 1:22:38 PM Warning: Lost connection to Duet (Board is not available (no header))here's a picture of the old system -right side of the picture at the end of the 20x40 extrusion (again, its not pretty, I'm not proud of it, but it worked):
basically I cut a slit in the GT2 belt, and sandwiched it around an M5 bolt that clamped 2 plastic pieces around it. This bit into the aluminum as there are spots where the anodized coating is rubbed off. My theory is this somehow connects the belt to the aluminum extrusion piece - am I wrong?
Here's a picture of the new belt tensioner:
There's a connection between the pulley on the X-axis and ground, so that doesn't seem to be helping with the discharge issue. But it does seem like the belt is somehow the issue. I'm probably going to try the old tensioning system and see where that takes me.
