Rigid Frame for SmartBench CNC Router

[@joshsoorlin579]

make more vis of the smart bench great idea man

[@Karvdcnc]

Very keen to see more of this I have a smartbench and looking to do something like this

[@PaulSteMarie]

I'm real curious about how this proves out over time. My projects using 80/20 extrusions have mostly used the blind connectors and gusset plates, not the angle brackets. 80/20 technical documents indicated that the blind connectors were the strongest, which is surprising considering they're also the cheapest.

John do you happen to make molds for people? I would like to hire you to make a mold for me for use with a buster beagle injection device if possible.

Why not just put 1.5 mdf board as your spoil board !!!

Weird design. They must have done that to save costs - but boy does it like to flop around.

I dont think you understand how this machine works. Your accuracy in the z axis is going to be degraded with that there.

[@craigsunderland3849]

Can you explain? The video clearly shows bumpy y-axis movement as the gantry travels over previously routed material. As soon as a rigid frame is there, that doesn't happen? If there are dips and rises in height you are bound to see less z-axis accuracy.

He just needs to move his wheels to avoid the bumping on the z axis. Doing it this way the xbeam is unsupported so he’ll get variables in the z axis height and the angle of the cutter. It’s just not designed to work this way and it’ll flex. He trying to use it like a traditional cnc but they are heavy duty to resist against flexing, the SmartBench needs to roll on the surface of the material to maintain accuracy.
