Genmitsu 3020 Pro Max CNC
The boxed unassembled CNC from the recent bulk donation is a Genmitsu 3020 PRO MAX. The V2 comes with the controller and PSU pre-mounted and mostly pre-wired with a cable chain for the X carriage, so (based on what we saw when we checked and re-packed the box) it looks like we have the original model, now discontinued. Last price: £341 + VAT.
The original assembly instructions and user guide should be on the USB stick that we have seen in the box. Reviews give the build time as approx. one hour, so it should be viable to get it up and running in a couple of evenings.
