5'x3' Ideas and build.

[JAZZCNC]

Jazz, when you say that you wouldn't build the gantry in the way that I'm planning on doing it - do you mean that it's a shite design that won't work, or are you coming at it from a purely expense/ball-ache factor?

No not shite and with some modification will work fine I'm actually building something bit similar.



I was thinking more about the cost and the work involved for someone without another machine to help. Which from reading your post's I didn't think you had.!
Thou still I wouldn't do it like that to be honest has it's too inflexible regards adjust for things like ball-screw alignment etc.
Keep the shaped bottom if you like but I'd drop the extended/slotted front plate idea and go with adjustable stronger brackets for ball nut mounting.

Like someone pointed out you absolutely need piece across top for support. I'd also put in some braces between upper/lower and front across the width to help reduce resonance and all though these pics don't show it this gantry has two. They also provide support/fastening for a rear plate enclosing screw and stepper.
