But moving the thermocouple wires away from the other wires didn't help
Only one of the thermocouples for the right extruder now is working correctly, but i can't say exactly what helped, maybe i crimped it better. Although it still can catch the interference from the other thermocouple, even if using it alone does not provoke interference
They are still near the drives on the head, and i think that is where they pick this interferenceI wonder if using a thermistor will help
Flexion extruder allows to install it, and the board has ports for temp sensors -
recrimping didn't help, i think I'll have to go with the thermistor
that way i will not need a daughterboard and i guess that might help -
Captain's log
Installed and configured thermistor NTC 3950
Now I don't see 2000 degrees when extruding or retracting filamentBut my printer shuts down in a minute after that and then it is trying to restart over and over again, until I turn it off and turn on again
-
It seems that @dc42 helped me again, even without saying a thing)
I found my answer here https://forum.duet3d.com/topic/15897/duet-wifi-resetting-part-way-through-prints/30
I disabled endstops, and it seems that the problem is solved
Though I need to wire the endstops properly -
@oliof I think you are right, I didn't understand you at first) thank you)
-
Sooo, I did recrimp endstops
Thought now it is ready to go,
connected Cura via plugin OK
Started to heat the bed
After the extruder fan started to work the printer started to restart again
Then in a few minutes, after the printer cooled down, I thought I'll try to change some settings for fans
But the printer began to restart in an idle mode. I did nothing, and it started its disco.Now I don't know what can be the problem
Maybe something should be done to a board fan frequency, that is the only thing working when the printer is idle -
Ok I started from scratch
I think the problem was with the board loosely fixed, it might have touched some parts of the case
I also checked all the wires and reinserted them, trying to fix them as tight as possible
Now it seem to workStarted the test print, I'll write an update after that
For now I hear the sound of silence and it is great
I'll have to change the coordinates though, the print started on the corner of the build plate -
This post is deleted! -
Finally it is working
Though I need to adjust tool offsets a bit more
And I also had to change the cooling fan number in cura settings for every extruder to the pin number of the fan (in my case fan #3)
And I need to try dual extruder printingThank you all who helped me achieve this.
Hope my story will help somebody)I'll publish my design for the Big Dipper holder and my configs a bit later.
-
Here is my design for the holder
https://www.thingiverse.com/thing:6781025/filesConfigs have to be refined, so I will post them some time in the future
-
New update:
After some prints, I saw issues with layers positioning at different heights. Tried to tighten the belts aaand my printer stopped working)For some reason the problem occured only when the bed was heating, so I recrimped the thermistor, because I made a mistake and the cables were in reverse order. Then I recrimped the bed power cables that are connected to the PSU. And I did that for a week or even more every evening)
I found out that I used 1.27 mm2 cable for bed power and that I had to use the right crimper tool
And I tried and tried, again and again to crimp even better
Until I checked the bottom of the board holder and found out that extruder cables touched the screw
I guess that was enough to short the board
My board firmware even got corrupted and I had to reflash it via USB
It even stopped connecting via serial port, only direct USB download of the .uf file helped meThen i also had to fix other cables as well that touch the closing door of the bottom side of the printer
So I write this to warn you to be careful with your wiring)
But I still have this issue with my layers though. So I will continue to look for a solution.
Also I took the opportunity and installed the Z-probe, though I need a holder to start using it
And I haven't configured it yetAlso I found some useful resources along the road
For example a video about crimping -And a guide with pictures how to wire a dual extruder printer to the Big Dipper
https://www.youtube.com/watch?v=GZOh1NzqzzU
Although the cooling and board fans seem to be wired incorrectly there
https://github.com/FYSETC/FYSETC-BIG_DIPPER/tree/main/example/Independent Dual Extruder -
I guess another problem is with my power supply like @garyd9 had when turning on the bed heater
https://forum.duet3d.com/topic/3553/converting-a-flashforge-creator-pro-to-use-duet/3I wonder what should I take into account if I want to use a 500w 24v PSU
Should I replace the original 1.5 mm2 power cables?
Will the board survive the current?PS: it is interesting that I had some almost successful prints even with a 320w PSU
Although there were signs of missed steps -
Ok, I think the PSU was not a problem, because I get shutdowns even with the 500w PSU after trying to run a bed heater. Though I had some restarts in the idle mode too. Also after the shutdown it was hard to recover on the old PSU. With a new PSU it's the board manages to restart. Or maybe I crimped the wires a bit better now, but not enough for the bed heating
Two times I managed to catch an error Vdd Brownout

@Inlinebrother although your board is a big dipper as it uses the same MCU, dc42 may be interested in the output of the hard fault issue.
