Vertical fixed gantry. Design & build. (Steel/epoxy)

[Greeny]

Well must say That's an ambitious first machine.?

Yes, it has kind of got out of control!
Should be fun though, until it starts going pear shaped.

Thanks for the advice on chip protection/clearing and raising/tilting.I hadn't really given either a great deal of thought.
Will ponder more on those.

With the Gantry raising and lowering in place of a typical Z axis then I'd connect the screws with timing belt rather than using twin motors, you'll keep screw sync much better.

I am definitely thinking about one motor for both screws. It seems both the simplest and best way of syncing the screws.
The gap between the screws is ~1770mm. Is this something to worry about with belts?
Is it possible/feasable to have a central motor driving two pulley wheels (one for each screw) so each belt is half the length.(each belt would need a tensioner)
quick & dirty sketchup

Oh and why are those screws on the bed so far out.?

They are slapped on there as i'm unsure about pulley system & the layout for pulley wheels.
There is quite a bit of wiggle room so i should be able to finalise their position soon.

Thanks for the comments an advice
Cheers
