This printer is a redesigned one. The main aspect why i redesigned it is, that you can machine it on your small home cnc router.

The motors and the electronics are mounted on the top, because of heat dissipation and better access for maintenance. The six segments of the top and bottom assembly are all identical. The spool is mounted on top. Access is granted at all sides of the printer. Easy height change. Closed loop belts for better mounting, but also open belts are usable. A row of holes in the spool holder for diverse spooldiameter. Simple adjusting of the endstops. hollow carbon fibre bars. Motormount is just with zip ties and a screwed wooden u-block, for fast motorexchange An own developed effector. No vertikal extrusion profiles needed. The big effector should enable paste extruders and is more stable. The electronics can be mounted on top or under the top plate.
