Mill 480x500x180 RIGID

[Robin Hewitt]

It still looks a tadge wrong to me...

I thought the big advantage of the fixed gantry was that you could localise the support for the bed where it was needed. You put your rails on the bottom of the bed and your linear blocks under the gantry. There is no point in supporting the bed anywhere but under the gantry, you are just introducing unnecessary overhangs

The machine should appear as a gantry with a bed sliding through it

It is not perfect :)
I don't quite follow you though.
Do you mean fixing HIWIN rails to moving bed and bearing blocks to main frame?

Correct. You can remove a lot of unnecessary iron and make it stronger.

Remove the overhangs and put the support where it is needed.
