1.9 x 1 m sand table corexy mechanism that's been switched from cable drive to belt drive. I didn't trust the cable system. The pulleys were noisy, and if anything went wrong, restringing cables took about an hour. Belts are far more reliable.
The motor mounts, Y axis sliders, corner pulley blocks and magnet carriage were all printed in ABS on UMMD. The pulleys are stacked F623 bearings, the motors have 40 tooth drive pulleys. The mechanism is driven by a smoothieboard.
