Hall effect sensors >> assuming straight contact closures here, not active

I am at a decision fork.
1) Spend money and time on this hardware, get better performance. Or
2) Sell this and build my own repstrap like version run by with steppers
and linuxcnc.

I intend to put a flame cutting head on it for small format steel sheet and
plate.

With a head swap and sitting on top of a Z stage I want to experiment with
liquid binder based 3D powder prints.

I already have steppers, several drivers, acme leadscrews. It just seemed
tantalizing having the complete xy built already minus the control.

Don't really want to put $300+ into an experimentation platform that ends
up slower than what i could build from my "junk" box.

All thoughts/comments welcome!

Best,
Jason
