Default Machine noise

Hello all,
Question for anyone but mostly for Pro4824 and HJ. I've had this clicking sound in the Z axis from day one. Is it normal? I get good clean cuts so never worried about it. I also hear what sounds like R2D2 from Star Wars.
Strange, let me know what you think.
Thanks

How well is the ballscrew lubricated on the Z axis? What about the washers and couplers - any slack in them? Can you move the ballscrew up and down with it powered off?

The clicking sound is not normal. The R2D2 sound you describe is normal; it's the stepper motors working.
If all your hardware is tight on the Z axis, I would call CNCRP about the clicking.

I would also post this on https://www.cnczone.com/forums/cnc-router-parts/
Someone from CNCRP is likely to see the post and give an answer.

Thanks Bob, I will post there and tear into the z housing to check out the ball screw. Just o over everything again. Like I said, it's been that way from day one. Oct. I think is when I got it.
It runs great...

Wow! Something is definitely wrong. Sounds like missing bearing in the linear rail blocks and the bearings are clacking because of open space. Did you grease them?

I recall someone posting about losing bearings from the CNCRP Z axis. Sorry, but I can't recall the forum and I can't find the thread. Anyway, he did grease the bearing blocks and the bearings pushed past the end seals and dropped out of the block. When he started having problems, he opened up the axis to see what was going on, and bearings dropped out. He also had a picture of the end seal warped out of shape. I don't recall what his symptoms were along the way. Highlights the importance of proper lubrication.

I suggest you call CNCRP, get an email address, and send your video to them. They can probably help you with the diagnosis.

As the click happens whenever the Z axis changes direction, a missing ball in the linear bearing block or in the ball screw seems most likely.

You can email CNCRP direct or talk to your salesperson and they'll send you new bearing blocks under warranty. The first ones I tried putting on lost a few ball bearings. They said not to run it and sent me 4 new ones, which I was very careful with.

The other sound is normal.

I took the tests and retirement is the best job I'm suited for.

Now I know why old guys wear suspenders.

As probably with your machine the whole Z housing (ball screw, rails, and bearings) were per assembled, I just mounted it. Now that you have said that about the bearings, it sounds like maybe...
Thanks everyone!

I opened up the front, everything looks very clean and tight, but notice the gap between the couplers.

Motor mounting bolts a little loose?
If you can't find the issue, your best bet is... [email protected] that guy is amazing. My X was clicking and he instantly diagnosed a R&P belt that was a little too tight.
