The best i3 so far. All metal. Great price. Works well. The new one puts the control and ps in an enclosure, might save some time in the assembly. Minor problems: Some re-tapping was necessary because of the anodizing. have some metric taps on hand.
The tolerances were terrible on the black metal bits that hold the rods, which hold printhead going side to side. Partially it was the powder coat and partially it was the metal. So expect to Rheem out 8 holes for the rods. You could also use a sharp drill bit on its side.
The worst problem is the couplers from the Twin stepper Motors to the metric lead screw. when I say lead screw it's more like metric ready rod :-). you must shim the lead screw so it centers in the coupler.
Otherwise the lead screw will move side to side too much when your printhead is low. this can lead to motor jamming and missing steps. it would be nice if those couplers were tapped on the top.
This is one of the best Prusa kits you could buy!
This kit is very robust and easy to assemble. You can tell a lot of thought has gone into the design of this printer; there are many clever little details in the design. The instructions are far better when compared to other Chinese manufacturers.
