Hello. I just purchased a Hwacheon HI-ECO 21HS machine. Fanuc 18T control, sub spindle, live tooling. It has some mechanical issues - sub spindle was crashed, and the linear bearings on that axis are damaged along with the rails....a few cap screws were broken off which looks fun to fix. I am looking for a manual on this machine if anyone has one. I'm able to zero return all axis but Z which over travels every time. The limit switches are working and registering, so maybe a software limit?


Also weird, but probably just something simple, I can zero return c-axis, and jog it, see the position changing on the screen, but the spindle is not moving. Is there a manual gearbox that must be engaged via M-code even for jogging?

Anyway just looking for some general info on this machine and/or a manual thanks.
