Voron 0.1, built from a cheap kit, with lots of bad-quality clone parts. added a glass bed, and a Bondtech CHT nozzle. even with the bad parts, if i get things aligned and fed properly, it still runs nice.

this video shows it printing a calibration cat at 300mm/s, with a bit of slowdown for overhangs (manual adjustment), travel at 800mm/s. the video is real-time and unaltered, and was taken and uploaded directly from my Galaxy Fold 3.
