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.
So, I got in touch with them and they are very friendly and happy to answer to various questions.
The price it’s fair and the machines seem in a good shape but honesly, it’s not a great game changer from a normal prusa, reading online the stiffness of the printers doesn’t do…anything…especially as they don’t have vulcano hotends or improved cooling.
Still, if you want a prusa printer for a fraction of the cost of a new one, go fot it.
“Core Heat Technology” for anyone else who had no clue what that was The top orifice is actually three smaller holes to increase the surface area and therefore the heat conduction. This allows faster extrusion.
