I’ve just bought a second hand Caribou Mk3s 320 and it seems to be in very good order. I paid £360 for it. He has 8 more (selling from a print farm that went bust) - I think he would take offers for several if we wanted in the space, or indeed if anyone else wants one.
Caribou / Zaribo printers are Prusa Mk3s printers but overspec with super rigid frames, mine has a bondtech extruder. I’m running on the Caribou firmware and using prusa slicer and all seems well so far.
Happy Monday all!
