Leftover cheap 1/2" plywood. Drew up a strut in coreldraw.
Exported the svg. Cammed it out in estlcam with a 1/8" bit at 900 mm/min for a doc of 7 mm to make it a quick 2 pass operation and sent the saved gcode to the lowrider.
Homed, then moved to cut area and probed but forgot to zero x and y.
Broke the bit because it hit the holding screw first thing. Replaced the bit and cut first inner parts and the core caught on my holding piece and came off the rail. edited the inner parts out of the gcode and recut the outline. Didn’t write down initial position offsets, so got close and one if them is offset a few mm on the outline.
The goal was to use some old plywood and the old conduit rails from the mpcnc to store filament.
Screwed them into the basement ceiling floor joists, slid in the conduit and they just work.
