Thread: The New Machine
I expect the cutter needs the weight of the head to give it "balls"
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.

i used the keling kit with 900ozin on Z and 381 on the XY.
The X is rated at 900oz but the drive is only delivering 3.5 amps so i think it is 500oz.
Have you go the motors and and drives because i would recomend the kelinginc kit as the motor are low impedance and give the best performance. UK motors seams to have a lot higher impedence and poorer performance.
Edit, actually ignore that - found it:
To be fair that's quite a low inductance for that size motor. Still with a Nema 34 motor you really should be running it on a LOT more than 50 volts.
