Just a question of curiosity:
I built my machine using high grade Kuroda GG1515 ground ball screws, pre-loaded for zero backlash. They do an excellent job and I try to keep them in good shape with proper lubrication and dust shields.
As it happens I place parts to cut typically on the same spot of the table, mainly out of convenience. Now I am wondering if I should rather clamp them on different spots to distribute the wear on the screws and linear bearings better. Or are the screws and ballnuts anyway so durable that it does not matter and they will survive me, given that I use the machine in average an hour per day? Most of the work the machine does is short stroke 3D and V-Carve. I could not find much information about durability and wear on the ball screw manufacturer's web sites.
Any opinion? Thanks!
Edit: Sorry, that question belonged in the higher level section, not the project log.
