OK, found some setting son line and it seems to be quite happy now, obviously it’s not super square, but I might try and see what I can get out of it before we reengineer it.
Other than squaring more we might also think about a big red stop button and then some limit switches.
Also I put in a different dremmel from the store room that has a UK plug, didn’t know where to find an adapter for bmslieght’s one.
It is very very noisy, but I think you could happy do circuit boards, maybe even some 3D stuff in tooling board.
It might need a sound damping box with a window to go in…
