HDZ Catastrophe

So I crashed my spindle into my work piece five days ago. Over the weekend I went over everything, replaced 2 v wheels, tightened all the eccentric nuts, recalibrated the belt stretch, and all seemed to be good.

Cut a few parts on Monday, and randomly, on some plunges I would hear a clunk.

Last night I was trying out my new laser and heard a THUD, my spindle dropped and the laser hit the ground. The two screws on the nut for the ball screw had backed out.

Now I have a bunch of tiny ball bearings that fell out of the slider blocks. I’m sure that a few are missing. Found one bearing 10’ away with a magnet.

My questions

  1. Do I order more ball bearings and reload the slider block. If so, what size ball bearing?
  2. Do I buy new slider blocks
    3 How do I tell if I screwed up my ball screw

Suggest you open a ticket with C3D support. They’ll fix you up.

I’m going to check some screws…



Call support, those linear bearings are not the easiest thing to re-pack and they need to be clean too.

If you can still turn the ballscrew by hand and it’s smooth and the ballnut goes up and down then things should be OK with that, looks like it’s just vibration loosening the bolts.

And I’m off to see the ballscrew bolts with some loctite too…


Well, on the bright side, that “Z” does reach the spoilboard…


Contacted support and they told me to pack it up and ship it back. It’s going out tonight.


We might occasionally focus on the shortcomings, but for all that, Carbide 3D is an excellent company IMO.
