Have any of you ever broken a Prolight down for maintenance or upgrade as far as the ballscrews, linear rails, pulleys, etc.? I have taken the table off to get at the saddle and while I was doing that, was going to see how practical it would be to change the timing belt pulley size on the ball screw. Long story short- I used a pulley puller to get the thing off and now see that it does not use a key or a flat with set screw to keep it in place- basically a friction fit with the set screws on the round shaft only. I am concerned about damaging the ball screw/ball nut when trying to get the pulley back on by tapping it gently with a rubber mallet.
Also, if anyone wants pics of the balls screws, ball nuts, and all that from under the table, let me know and I will post some. I was always curious about the design and setup but didn't want to take the time to look. We have some time to do some more in depth maintenance and tweaking at the moment and curiosity got the best of me. By the way we have two machines and they both have different ball nut, bearing set up, and coloring of the polymer granite base. One was purchased from a medical company though and may have been modified.
Any advice on getting that pulley back on would be appreciated and let me know if you want any pics of the mills while I have them broken down.
Best,
Ryan
