This machine is an X/Z gantry with a moving Y-table (bed). The nominal machine travel is X 350mm, Y 280mm, Z 160mm, however the Z clearance (max. work height) is only 60mm, and we loose a bit of X and Y to limit switches etc. so a more realistic workspace is 345 x 240 x 55 mm. The gantry is nom. 380 mm between uprights which limits work overhang off the sides. * Modified 3-axis OpenBuilds [https://builds.openbuilds.com/builds/c-beam%C2%AE-machine-plate-maker.2020/ C-Beam 'Plate Maker' CNC Router].
