Official repo says $114 per arm, but I didn’t check their math :) https://github.com/huggingface/lerobot

Was just thinking that if the goal of your video was to showcase the difference between the bed slinger and the corexy, then it would’ve made a stronger point if you took advantage of its full potential. The MK4 even looks faster in the video, but I suspect it could be the angle and that the bed moving making its motions more visible.

At that printing speed I doubt it makes any difference if the bed is moving or stationary :) Surely the Prusa XL could go much faster than this?
