What's the price on these?

[gio666]

come with THK or Hiwin

[gearsoup]

Are you referring to the Z axis on the left or right side?
How does the ball screw like being unsupported like that? I realize it is a small distance, but I can't imagine that it loves high rpm's

Z axis has no problem with one ended ballscrew at 900 IPM

dang! If i build another machine ill buy one from you. how much?

How do you keep the dust out of the ballscrew nut ? Cutting MDF would get in past the seal and stick on the grease (ballscrews need grease).

Nice machining .

Invest in a quality vacuum system that surrounds the bit.

Well just do steel and aluminum then , lol joking ,I see on your machine, you have kind of the same design as mine , but have acme screw , ? so why would dust affected these ones and not the same open screw that you have ?
#1 don't over grease ballscrews or bearing , grease every 100km of use

I guess you've never cut a lot of MDF. It goes everywhere, vacuum or not.

Lol , No You have the same design as mine .

I use a Kerk delrin nut and stainless screw , I've used ball screws in the past but they are terrible in the dust. The eventually jam up with dust in the balls especially with stepper motors.

Hi, I acquired a cnc frame and gantry made by Shop (S)Cam Routers Inc, and I believe Larken was the original designer. So maybe you (Larken) could help. This thread is what I have been looking for. This machine, which I have built the controller for and am trying to get set up to run flawlessly, has one of these Kerk delrin nuts on the z axis. The z axis gets stuck. Is it the nut or a motor setting? Do you know what settings should be entered in mach it uses a Vexta PK296-F4.5A stepper.

Any help would be appreciated
