Determining belt tension


#1

This is a question probably suited even outside of the Wilson specifically, but I’m wondering what kind of guideline I should use for the belt tensioners. My y-tensioner is squeaking quite a bit, have been playing with it to try and get it to squeak less (loosening the tension, loosening the screw/washer that goes through the bearing, etc).

Is it possible the squeaking is just because I’m “breaking in” my new printer?


#2

It probably is the plastic bearing guide rubbing against the teionioner yolk - plastic to plastic. Sometimes mine do that, and I put a drop of 3-in-1 or ptfe oil on the outside of the bearing guide and it stops. Sometimes it comes back, sometimes it seems to wear in and not do it any more.


#3

I used nylock nuts for the M4 bolts on both tensioners, so that I didn’t have to tighten down the yoke to the point of squishing against the pulley. It could also be the tensioner squeaking inside the Y-end as it rocks back and forth a little. Does it only squeak when the Y table changes direction, or does it squeak any time the table is moving?


#4

It seems somewhat random, almost depending on where the table is located at the time. Perhaps this means it’s dependent on the amount of tension being put on by the table + belt + stepper?

I’ll try the oil. Recommended buying sources?


#5

You can find 3-in-1 oil almost anywhere. I know Walmart sells it, and any hardware store should have it.

Heh, I should be honest. The lazy guy in me was hoping for an amazon link… :smiley: I’ll search myself, no worries

You could just go to Lowe’s too.
