How It Scores
Pros
- +420x420x480mm with Klipper for $469: the price-to-volume ratio is hard to beat
- +Direct drive on a bed this large is unusual and useful for flexible materials
- +Klipper gives you full control to tune speed and acceleration for the mass of this bed
- +Prints full armor breastplates in a single run
Cons
- −Open frame at this scale means ABS warping will ruin prints without serious prep
- −The sheer footprint means a dedicated table minimum; don't try to share desk space
- −Slower effective speeds on a 420mm heated bed: physics wins eventually
