I have a NEW, never cut a chip, 2000 Cincinnati Arrow 500 with glass scales and Vickers Drives. The machine was installed in a clean room and never run. Pulled out a few months ago and brought to my shop in Hawaii. I've got it installed, leveled and sent the boards to Fives for batteries and reflash of bios. Fives also supplied a new SSD.
One of the machine parameters was set incorrectly, so it wouldn't drill to commanded depth (.100" shy). Got that figured out. Now it's working great! It's sounds like new - heck it is brand new!
My new problem is:
I've programmed (Mastercam) a contour cut rectangle with a 1/4" end mill. The part is about 1.5" x 9" and the depth of cut is about .45" Radial engagement is very light - clean up cut - maybe .015". About half way through one of the long sides I see (and can measure) a step of about .0015" It doesn't do it every time (I've got several to cut), but about one in five parts or so...
As this is essentially a new machine and may have not been set up by a trained technician, I'm wondering if there is some parameter that drives accuracy that works with the glass scales to maintain position? Anyone with one of these (glass scales) up and running, can shoot me a screen shot of parameters?
