Okay, Long term- I will probably rebuild the Z axis and most of the gantry. Problem is, I cant really mill aluminium at the moment. too much flex in x-axis. Heres what im thinking of doing to get it a bit more rigid.
Add two 15mm linear rails (4 carriages), to a 120x530x20mm aluminium flatbar backing plate (fixed to gantry). A 2020 extrusion top and bottom to aid fitting.
Here is the before and proposed after...
I'm worried about the flex in the 2020 extrusion. Anyone got a better idea?
Thanks.

Just an idea but you could replace the gantry completely with new aluminium plates and 9045 extrusion, if you take it real slow you'll be able to make them on your machine.

I'll almost certainly end up doing something like that in future.
I want to try this first though. If it makes enough difference, I can mill my own parts out of aluminium to rebuild the way I want.
Just now i cant even trust drilling operations on the machine- far too much deflection on contact with material- even going really slow.
I have another coupla plans I'll post. I need the feedback.
