Been throwing around the idea of building a cnc mill, the end goal is to hopefully be able to mill most materials (although i believe in this first iteration rigidity will be an issue)

I have compiled a list of components I believe I can cobble together, the feedback I'm looking for is if anything will absolutely not work together, if I am missing a component, and any huge safety issues.

Drivers:
https://www.geckodrive.com/g201x-dig...tep-drive.html
x3 = 327
heatsink = 74

Axis Motors:

X3 = 359.85
16 awg wire

Controllers:

pmdx gecko mobo:
PMDX.COM - Products for CNC and motion control applications
x1 = 55
pmdx 126 mobo
PMDX.COM - Products for CNC and motion control applications
x1 = 174

spindle controller:

x1 = 57

x1 = 305

chassis c-beam machine:

x1: 589.99

spindle:

x1 = 390

vhd: hitachi nes1-015sb

x1 = 201

total: $2713-ish

Right now the problem I view is rigidity when working harder materials, I just do not have faith in the c-beams to hold up to the torques that the spindle and the nema 34's can apply to a workpiece. Also I do not have a vice selected right now that will be more of an addon.

I am hoping to use this as a platform to upgrade itself although I am now questioning whether I should instead build a plasma cutter to be able to cut a heavy frame for a future mill.

Thoughts, concerns, ideas?
