It is my intent to re-ball my screws but after removing the bely on the Y axis I found that my Y-Axis, on a J325, is very tight. It moves but nowhere near the ease of X or Z, both turn easily by hand and will continue to spin with a quick twist. I would like to reduce the drag before I replace the balls. What are the items that cause drag? The ways seem to be well oiled, the ball screw is clean. Are there other adjustments I should look at before the re-balling, like the gibs? If anyone has a Tree manual that shows the parts that would be extremely helpful. Do they need to be cleaned?
I see there is a grease fitting on the Y-Axis shroud - I have never greased it could the bearing be an issue?
Sorry for all the beginner questions but I am in the process of starting Retrofit 2.0 and want to cover as many maintenance items as possible.
