Video of CNC machining a double sided part.

So how did you align it to do both sides?

I usually but the piece against a fixed bar to get it in line on one axis and then jog the cutter to a hole on the piece in a known place to align the other axis.

I'm off to make a waveguide today!

The method your using isn't accurate enough. Not for a two sided part because any error is going to be multiplied by a factor of 2 when flipping it over

Two reference edges cut in a surfaced jig to align the stock parallel to the X and Y and make sure its flat. Then 4 dowel holes were drilled through the jig, table and stock. Took awhile to figure out but its very simple and effective. All datums were at home switch position because the part couldn't move or misalign thanks to the dowels. That meant no probing needed and one less potential error that could creep in.

I was wondering where Jazz had got to. Hadn't seen any recent activity from him, anyway hope you get better soon.

Ant, if you don't mind and when you got time, I'd appreciate it if you could make a short video of the above method. I just can't get it round my head. Doesn't have to be another £300 speaker mould, lol, just a piece of scrap for visualisation.
