Steel/Aluminium design/build, sorta smallish, cuts ali hopefully

[mart154]

Ok, I updated the drawing a bit.

Did the "PFC mod", tho, now I have to fit the Y ballscrew somehow between the gantry and Z I suppose, so this is still going to change a bit.

Redesigned the bed a bit also. Didn't save any steel tho :)
Decided to have the extra steelwork under the bed just in case. Who knows, maybe I'll mill myself an engine block :)

Now the bits that could introduce side distortion are in one piece and there's a box everywhere under the edge of cutting area.

Left the green 30x30 bits in place. If I decide to have the bed only as big as the cutting area, these will help to mount "cutting fluid collection / mess containment solution"

I plan to cover the sides (and the edges then) with plywood or mdf or 1mm mild steel or something similar.




Now, couple other questions have risen as well.
First, on this picture below theres a 15x60mm riser plate under the gantry. I was wondering if it might be worth extending it and put the X ball screw mount straight to it instead of the gantry endplate?


Secondly. At the moment my Z rails are spaced 75mm apart, is this going to be enough or should I widen it?


I must thank anyone yet again for feedback. And for this forum in general! Amazing source of information!
