Working on my design for the Z axis. Which would be better way of driving it? Motor directly attached to the screw or a geared solution? Ideas anyone? All the other designs (Hoss, Fignoggle etc...) have it belt driven. Eric |

I can't remember seeing any direct drive X2 conversions on cnczome, all have used belt drive for greater torque. In theory it could be done but you would (probably) need a NEMA 34 rather than a NEMA 23 motor. |

So, I am going to hold off on finishing up the Y bearing/motor mounts and start on the X. Going to see if I can start it tonight. X axis will include; a longer acme screw, an acetyl nut and new motor mounts. I am going to gear the motor like the Y axis is.

Not a chance that the original table will work with it is there? |

You will OFC, need a new feed screw. That said, it is all hearsay. Until I have the base in my grubby little hands, we won't know for sure. If it doesn't I am OK with that as the initial measurements put it at very close. I plan to recut the ways anyway. The X axis is longer. I think almost an inch?? Not sure. The HiTorque has an X of 5.1" while the HF mill is 4". It is also a little over 4 pounds heavier. The part should be here Weds. I will let you know then. |

CNCfusion's kit is direct drive as well. Just trying to figure out which has the advantage. |
