I always enjoy reading about other people's printers, so I'll share mine I just finished.

It's a BLV Cube with a full enclosure, 7" touchscreen connected to a Pi 4, heavily modified toolhead, and some cosmetic tweaks. Really a great design, but everything could always use some upgrades!

Features/improvements from original design:

• Precision Piezo Z-probe
• Dual 5015 part cooling fans
• V6 hotend with Bondtech direct-drive
• 300x300 magnetic bed
• Raspberry Pi with Duet 2 Ethernet
• Lots(!) of LEDs

Possible upgrades:

• Watercooling for hotend and part cooling fans
• Better bed (currently I have a cheap aluminum bed with integrated heater)
• Toolchanger

A little bit of history:

This is my second printer build. I started out with a Printrbot, and designed my own printer using hardware from the Printrbot (just a standard CoreXY with linear rods, etc.). It worked quite well for about 5 years, with some significant hardware revisions and upgrades. I wanted to build a bigger and better one, using the significant lessons learned while building and upgrading, and I had some designs floating around in my head. I was originally planning on building it with V-slot, until I came across the BLV Cube, and loved it. From that stemmed this printer.

Now for the good part: Pictures!

Feel free to ask questions, and enjoy!

@Phaedrux I have separate 5v and 24v power supplies with the grounds connected. The pi and the 5V_EXT pins of the duet are powered by the 5v supply, which is always on. The duet switches the 24v power supply via a relay.

I believe that undervoltage event is due to me switching off the 24v supply once since the duet was last reset.

Interesting. I use nearly the exact same settings as you do, but the main difference I think is the part cooling. You have a single fan blowing from one side, and I have two fans blowing from both sides at an angle. I think what may be happening is that there is turbulence where the two airstreams converge on my duct, and this causes the heat to build up. I might try redesigning my cooling duct so that the two airstreams are more aligned.

Also, I really like your quick change toolhead. Very compact.

@chrishamm All appears to be good. I'll update when the current print finishes.

Update: Print finished successfully and with no unwanted artifacts. That seems to have solved it!
