Hall effect sensors >> assuming straight contact closures here, not active signals, right? 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!
