I just took the plunge and ordered the Onefinity CNC! Excited and daunted as I am new to CNC, though I have done some laser CNC. My main worry is the lifespan on the Ball Screw’s and how much they would cost to replace, and can they be replaced at home? I looked all over the forum and didnt see an…

[image] Jake: Ballscrews are not expensive and this machine appears to be easy to service when that time come. Get the machine and just enjoy it. Yes, THIS. Ballscrews are industrial-grade components and should be the least of your worries. The truth is, you’d probably have to have thousands …

Thanks for the feedback Bill, Jared, and Jake, very much appreciate your knowledge on the topic! I will stop worrying and just prepare my spot in the garage. I was already imagining some accordion like cover i could put around the round rails that would expand and contract as the gantry moved to pr…

Yeah, that doesn’t appear to be an item of concern, really. Nothing wrong with minimizing exposure to dust, but probably not a game-changer.

Here are two pictures a ball nut. They are designed to prevent anything from getting inside the internal part of the nut where the ball bearings are circulating. On both ends of the ball nut you can see a White ring. They are like big thick washers that are threaded to fit the screw. This is a wiper…

I considered using an accordion style rail cover also, but the mounting of it will be a bit tricky since the machine that uses stall based homing. The spindle gantry has to be able to make contact with the left and front rail ends without obstruction. I’m sure there’s a way around it but from what I…

That was my first thought about an accordion-style cover, is the stall homing. That would most certainly be an issue.

I am thinking of cutting some plexi shields to place on the inside of the Y rails. I think that would keep most of the dust off the rails. I don’t think the X rail is much of a worry

So Charley, I haven’t even got mine yet but think I should have some spare parts. What can you tell me that maybe I should get/order for spare parts. Standard size set screws?? Plastic parts? Any ideas? Dan

It looks like 1f just posted replacement ball screws to their site for a decent cost of 62.50. https://www.onefinitycnc.com/product-page/ball-screw-woodworker-version

Didn’t someone make external wipers to install on the 1F to help protect the bearings
