The New Machine

you don't need to counter weight this machine if the correct steppers are used.

A setup with light stepper and poor z slide ways will cause crabbing and stalling. You counter weight to reduce the crabbing of the head. counter weighting does nothing to the cutting force as the slide ways and the screw resist this not the weight of the head. It does affect the acceleration as there is a greater amount of inertia.

Cheers Fragger, I had seen a thread on another forum about the counterweight and threw the question out to see what everybody thought as the concept was one that i was not famillier to me , you are with the majority in thinking it is not required or even desired, In an Ideal world what stepper would you suggest ive got a 34.
