Very nice design! I have a lot of respect for people that model their design before building it. Looks as a daunting task but the right thing to do.

The printer seems to have all the good things, rails, 3 points bed leveling, and a direct extruder, nice color combination, not too many things sticking out the frame, and the electronics nicely isolated and accessible. Down the road you may consider chain cable guides similar to Voron.

BTW, have a nice belt tensioners there. How do you determine the right belt tension? I am using the deflection method with this scale https://www.amazon.com/gp/product/B00EPQGQIA

Thanks for your comments.
I ended up adding a counter bearing on the bottom to help with the belt forces, as well as a collar on the leadscrew above the pillow bearing to help with vertical/gravity forces.

Done at 21v although I don't think that matters much for this.

Yeah, voltage would only affect the current and power, and the time it took. Resistance is purely a factor of the temperature.

@nuverian Thanks, no prob, steal away 🙂 I can see that it is very error prone when wiring it up, so do take care. You may also notice that my plug can be put in the wrong way around. However, more by luck than judgement, my pin arrangement is tolerant of that error, other than the fact it won't work. I marked my plug so that I never put it in the wrong way - ha ha yeah right that didn't work! You probably should contrive a way to ensure that it cannot be wrong.
