A 300mm Voron Trident, second printer. Most of the mistakes from the first one are already in the past. The enclosure is what is stalling me at the moment, and the enclosure has been stalling me for three months.
The short version
- 300mm frame, Trident over 2.4 because z-motion is simpler and the bed mass is forgiving at this size.
- Stealthburner toolhead on a Nitehawk SB2040 CAN bus board, so cables down to the carriage are few and skinny.
- Manta M8P controller running Klipper, Mainsail for the UI.
- Bed mesh + pressure advance + input shaper calibrated from a known-good starting point rather than from the defaults.
What is still open
- Enclosure side panels. I have the parts. I do not have the weekend.
- Chamber thermistor wiring. Easy job, keeps slipping.
- A sensible filament runout sensor that does not false-positive on flexible filament.
Longer write-up
A proper build log lives on the blog. That post also covers what I would change on a hypothetical third printer, assuming enough years pass for me to forget the first two.
