On an axis-zero operation (power-up-restart), the Haas moves the axis until it strikes the stop switch and thus sets the zero.
I don't see how the stop switch can precisely measure the axis home -- I say this by looking at the design of the stop switch.
It seems, in practice, that if I re-home the axis's, then they do not return to the exact previous offset. It goes out by more than 0.0005" (½ thou).
Is this error unavoidable?
Is the Haas mill never meant to be turned off?
Is one's morning startup procedure supposed to include resetting your G58 (or whatever) axis offsets to match one's previous day's work?
What am I missing?
BTW I machined a 3" round pocket in mild steel and the inside diameter was accurate to 0.00015" (0.15 thou). So this machine is in good condition.
Thanks!
