Not flaming/accusing, but I've definitely fatigue failed wires within 3 weeks of testing with poor routing choices and/or non-flexible wire choices.

"occasional strain" can fatigue fail wires.

I've also rectified that by using high-flex regular wire without noticeable issues. Just don't use CCA materials and you'll probably be fine. 🙂

Ok, I found the issue.

The steppers didn't work, because I had mapped all of the Duet drivers as extruders. Line 26 in our config. This is adopted from the Hangprinter config file.

I assumed that the drive number reflects the E-number in the Duet 2 wiring diagrams, but seems that this not the case. So, deleting the E0:1:2 from line 26 made the magic happen 🙂

Extruder is now ready. Finally!

But, then another issue surfaced. Again. It has nothing to do with Duet. One wire on our proto board had a bad solder joint and it got in contact with another pin (probably a power pin). The result was a fried Arduino Nano...

Trying to get replacement today. Can't wait 🙂

Very nice! Only few centigrade off.

@T3P3Tony originally we wanted to have the temp daughterboards attached to the extruder as well as an Arduino Nano for reading out them. The very same Nano controls also the LED color based on the average temperature. For time being we have to transfer the temp to the Duet and then the RGB signal back to Nano.

Of course now we will have the option to adapt the temperature range of the LED color to the actual temperature set point, what makes this even better.

Anyway, thank you very much! Now, it should be pretty safe to say that first prints are to be expected next week. Of course we will post videos 🙂
