I have no clue what kind of machine I have, but the crate says China on it so I'm posting here.
I have had the machine for about 12 years now, so for the money I spent, I'm doing pretty well. Recently the X axis starts randomly sticking in the middle of a run. Sometimes right away and sometimes not for 30 minutes, and sometimes works fine 1-2 hours before sticking. When it sticks it is temporary, and misses 1-2" then works fine, but at that point the piece is already ruined and the balance of the run is offset by that amount.
I'm not a machinist, and really have no idea what I'm doing but these are the things I've tried.
- I have noticed if I tweak the rails it seems to make a difference. Can't tell if tightening them or loosening them makes the difference but it only seems to last momentarily
- Cleaned the ball screws and rails, then applied a silicon spray lubricant. Didn't seem to help at all.
- Tightened and loosened the ball screw. No noticeable effect.
-Checked the wiring to make sure there were no loose connections
Ideas I am considering
-Buy a new Stepper motor for the X axis
-Replace the bearings on the rails
If anyone has run into this problem or has some insight in how to fix I sure would appreciate some guidance.
