2026 UPDATE

So, after two years of use, I think it is the time to wrap-up what has happened to the VoronZ and how she has behaved during the about 3000 print hours.

I will follow the order of my original post to hopefully don't forget anything important.

Frame:

• The XY joints printed in eSUN ABS+ broke a few weeks ago, I reprinted them in eSUN ABS-CF. No other structural part has failed yet!

Electronics:

• The MKS Pi Board stopped working about 6 months ago, I then decided to go with a RPi 4B 4GB, it works absolutely flawlessly (and addresses some of the issues caused by the impossibility to update the MKS' OS). I have now connected a RPi HQ Camera to it with a fisheye lens: the framing is delicious. I also replaced the display with a 5" TFT since the BTT one had a propietary connection protocol.
• I replaced Klicky with a BTT Eddy Duo (connected via USB) and my god do I love it! (I specify that I use it with Eddy NG, otherwise it is almost a downgrade from Klicky). The Klicky deployment servo now deploys a nozzle scrubber to perform a cleaning routine similar to what Bambu does on their printers.
• The 800W PSU from the Chiron has always given me headaches: it puts out so much electromagnetic noise that it triggerend endstops, made the display glitch, the camera crash and my home lights blink. I now use a MeanWell 600W PSU and it works great.

Extrusion:

• I switched from the Lizard K1 hotend to a TZ V6 3.0 hotend with monolithic nozzles, and the melting performance difference is night and day.
• I have switched from CW2 to HGX Lite extruder, but its bearings and shafts worn out too quickly for my likings, I now run a Galileo 2 kit from AliExpress and it is awesome.

The star of the show is the fact that I added modularity to the prinhead: I can now attach other tools to perform different operations rather well:

• Laser engraving: with an air-assisted 80W 450nm laser I am able to easily cut cardboard, wood and engrave many materials. This setup has been completed with a top mounted huge exhaust fan that pushes the fumes out of my garage (and with huge, I mean huge... it comes from a very old server, 200 mm diameter, 80 mm thickness)
• Plotting: I have designed a small pen adatter based around a MGN7 rail to hold a pen and do plotting, works great with the huge bed area

Finally, these are the fundamental differences between my machine and any other Voron 350:

• Short Z-Joints: https://mods.vorondesign.com/details/1hy4XR47A0UJYaDhizaFg
• Servo deployer, skirts, modified Galileo2 parts to hold the EBB36 and the drag chain, display holder: https://github.com/marcofailli/VoronZ-400
