I watched your video, the z plate you made, that looks fairly thin like 1/2"? Are you bolting it on top of the cast iron top plate? If not, I would make it a lot thicker, that thin aluminum will deflect a good bit if not. It's what is supporting all of the hanging weight and downward cutting force of the entire head. Another reason most go with a 2005 ball screw for that. I bolted mine on top of the cast iron for peace of mind. I initially used a 1/2" aluminum plate on my draw bar and that thing deflected almost an 1/8" visibly. The 3/4" probably also deflects some but not as visible.

Just a thought.

@lcvette, I agree with you about the plate on top of the colomn and do plan on upgrading that, the 16mm ballscrew I am using is well and truly more than sufficient according to the loads figures supplied, I am not planning on using an auto drawbar etc so its just the head weight itself.

Hi Chris,

I am looking to replicate your CNC conversion in the not too distant future.
I am curious to know what type of closed loop stepper motors and controllers you are using and where you bought them from.
