Huh, interesting. Was it working with any previous version? You might want @chrishamm to take a look at this one.

[Macgyver1307]

never worked first set up and I'm new to Duet. but learning lots!

[Macgyver1307]

any other thought on fixes? I ordered a pi 4 and it will be here Tuesday. Should I try stand-alone mode? thanks

[Macgyver1307]

could I have a kernel issue on the PI?

[Macgyver1307]

I tried making up Dupont jumpers and replaced the ribbon cable and still the same results as above. I'm thinking a duet 3 bord issue?

The no header error message indicates that the transfer ready pin works OK but the SPI data transfer did not. If you are not using DuetPi, please make sure that the SPI buffer size is 8KiB:

pi@duet3:/home/pi# sudo cat /sys/module/spidev/parameters/bufsiz
8192

If it is still set to 4KiB (4096), create a file in /etc/modprobe.d as explained here.

i checked and it is set to 8192

I suggest you follow this post and check what happens: https://forum.duet3d.com/topic/15551/duet3-pi-flashing-diag-led-after-wiring-24v-dcs-is-unavailable/119?_=1590153541635

@Macgyver1307 you can probably copy/paste the text from the terminal and save some bandwidth.

Presumably you're using the DuetPi image?

Lacking another Pi to test, as you already have the du-pont style wires ready you could try to use the SPI1 bus and edit /opt/dsf/conf/config.json. The SPI loopback testing doesn't test the clock signal from the Pi so its possible it could be bust I guess, but its hard to definitively point at one or the other without tools or replacements.

ref pinout.xyz's nice pinout:

(Or wait for the Pi4 come Tuesday)

[Macgyver1307]

yes sir! I started with that and did all of the testings from that post before I started this one. I can try the pin process again?

If you do, copy paste the output so we can catch anything amiss along the way. If using putty just use the mouse to drag and select text, which will automatically be copied to the clipboard ready to paste in the forum. Then highlight the text (in the forum post editor) and use the Code formatting button (5th button from the left after bold, italics etc).

[Macgyver1307]

ok sounds good ill start the process again and display the outputs. thanks for the help!

well I tried 22 to 28 ad 24 to 28 with the same output. I would post it but the form says its spam.

3 posts in a row to the same thread in a short amount of time probably flagged you. Please try again.
