put a hook on the unistrut at the center and a hole/eyelet at the top of the
sled so that when you need it out of the way, instead of disconnecting the
chains, just lift the sled up and hook it to the top unistrut
good call, I’ll work something up along these lines.
unistrut makes this very easy, you just slide the top strut in or out as needed.
not that easy, yes it’s movable, but it would still be a 5min operation and without a guide rail on the frame’s “Z-Axis T-Joints” could require a re-calibration. (even though the motor distance might not change much, it still could be askew to the workpiece +/- ~x mm.)
I’m just saying that there’s more work to do all around, and that if we focus on speed/agility of the machine itself, and developing some good solutions for common operations we’ll probably get further and faster than a custom solution to do a single operation (in this case, Vertical Full Length Cuts for breaking down full size stock)
