Large Format Dowell to Duet conversion
-
@charles-fraser from your description I would say its most likely the TC daughterboard that got damaged but you will need to add connections back one at a time to see what prevents the 5V power from working properly. I would be very careful adding anything that controls a heater incase the 3HC does have some damage and the heater starts heating with no control.
-
I removed everything from the 3HC - I'll do the process you mentioned. I also tried to update the firmware. This is what happened: It said updating, then okay, then when I tried to check the update it said:
-
@t3p3tony it's flashing four times, then two times, then one quick flash. Sirial tools crashed too.
I started SirialTools up again and it says:
-
@charles-fraser ok. lets take a step back. With nothing other than CAN and power connected to the 3HC what flashing do you get after a power cycle?
-
it's flashing four times, then two times, then one quick flash.
-
@t3p3tony I power cycled again and turned off USB power too. Now both 3HC + 6HC diag lights flashing in time again.
How long should I wait for the 3HC firmware to update? Will it say okay after that or does it take a min?
-
@charles-fraser
ok set all the dip switches to off (currently switch 1 is set to on). Then power cycle. You should see the LED flash rapidly as firmware is loaded. once the LED reverts back to flashing in sync (after 20 seconds or so) then set the switch back to 1 on, rest off, then power cycle.Updated as our posts crossed.
-
@charles-fraser oh it says v 3.3 on the 3HC too now! Okay phew! I will try reconnecting bits to see what's shorting the board. Thank you!
-
@t3p3tony Oh it's the 3D touch shorting it out! I will disconnect all of that. It's a bit of a complicated wiring with that.
-
@charles-fraser ok glad that you found what it was.
Next step is to get back to SBC mode and see if you can connect to the Duet in DWC from the browser on the pi.
-
@t3p3tony Aibo - easy peasy hehe
I replaced the thermocouple on the heat block with a thermistor because the thermocouple runs along the motor wires and is not sheilded down there.
Could you guess what could be shorting out the whole board on the 3D touch that would cause the heat cartridge heating to run off out of control please?
-
@T3P3Tony slight problem is I only have one SD card. Can I remove the SD from the 6HC and reflash it with the Duet Pi image and then just control from the Pi?)
-
@charles-fraser yes. If its the one that came with the 6HC it probably has dual partitions and may not need reflashing.
edited to add: make a copy of your /sys/ directory if you have edited stuff to not loose the edits.
-
@t3p3tony okay I have the Pi connected and updated the system files from an exact copy of the ones I had running on the board before but just uploaded to the Pi through USB
Here are my errors. Amazed how neither the thermistor nor the thermocouple (for the bed) are working.
-
@charles-fraser ok please post the contents of your config.g as you are using it now here (using the </> menu option to get it to format nicely)
-
@t3p3tony no wait the SBC is not connecting to the Duet. It says connected but when I run a command like M115 it just keeps loading and loading and gets stuck there
-
remove the M550, M552 commands from config.g
M558 should be set to type 9 (P9 in the M558 command)
Edit - Ahh sorry I see that.
Can you access the "system" page and edit config.g if so try making those changes. -
This post is deleted! -
Right so I unzipped the config file on the duet on my mac now and when I try to edit the config.g file I cant because it says it's locked; so I copied and pasted the contents of that file into a new text dog with the changes you specified (I think)

@charles-fraser, how come it was zipped in the first place? did you download the whole sys directory? what happens if you (in DWC) go to the "system" page in the menu, then click on config.g (if its visible).
