Who can guess why I’m doing this…
And if you’ve had linear bearings fail, were they also the ones under your X carriage?
I’ve had some fail on my Y axis. I then wrote a G-code that runs the x and y back and forth to find the source of the problem. From what I can tell, my problem was an issue with imperial 5/16" rods being used with 8mm linear bearings. With the rod being a smaller diameter then the bearings are designed for the rod sits higher in between the sets of rollers, then the rubber seal gets caught on the rod pulling it into the bearing and stopping motion.
Is this the same issue with yours?
I have 8mm rods, but the rubbers seals also got ate by my bearings…
Interesting, Have you measured yours to make sure they are 8mm because mine are supposed to be based on the kit I bought but because 8mm is harder to come by in Canada and 5/16" is very close, it might be common practice to sell the imperial rods as metric.
8.00mm diameter, I don’t have to deal with idiotic measurement systems in the UK.
@Anthony_Dewar you can get 8mm threaded rods on Amazon for pretty cheap. McMaster Carr has the 8mm smooth rods in various lengths if you’d like to order from them.
Yes I’ve seen the rods on http://amazon.com, McMaster Carr will not deliver to Canada unless its to a school or large organization.
I still need to look into the price difference between 8mm rod with the bearings or more common imperial rod with a machined Delrin bushing.
Oh wow, it was 144 weeks ago I did the X bearings. Y went a couple of weeks ago.
