Zonestar BMG Direct Drive Replacement

thingiverse

I designed this to replace the 2to1 cyclops hotend on my Zonestar Z8XM2. The mixing hotend has it's uses, but I'd rather use the large volume with a 0.8mm nozzle and print large things faster. The offset of the extruder also allows full use of the bed. There's 3 versions I've designed. They will have to be rotated, the bottom side printed on the bed. It's still a work in progress and the only one I've printed so far is the Volcano V1.0. For the Volcano V1.0, the only support needed is where the motor mounts. It may want to place them in other places but it wasn't required, I used support blockers in prusaslicer. Volcano V1.1 just changes the part cooling airflow path to hopefully cool the part better but it's not tested yet. Standard V1.0 is basically the same as the Volcano V1.0 but for the shorter heat block. Included is the Fusion 360 files to let you change it as needed. It uses a Bondtech BMG extruder, a pancake stepper, (2) 40x40mm fans, (3) M3 brass heat set insert, and (3) M3x4mm screws. I bought the inserts from here. https://www.ebay.com/itm/224041608092 The pancake stepper I used is the 14HR08-0654S. It seems to have enough torque to keep up with flow as the moving bed is the bottleneck of the printer.
