Doosan DHC400 with Fanuc 21i low battery alarm and x and y needs zrn alarm. Operator went to parameter 1815 and reset zeroes at wrong postion. Any way to know where original zero position was so I can reset 1815 there. I have original parameter blue book that came with machine when it was new.
You will need a spindle setting bar to sweep the bar diameter high point at zero/zero (for x zero) while rotating B axis B0 to B180. Y zero found by using gauge blocks under the bar from the table top and add the gauge block dimension to half the bar diameter to find Zero.Quote:

If you don't know how to do this, you'll need a few hours of time by a service tech.
Thanks. I have a service visit setup and still waiting. Was just hoping maybe there were some magic numbers in that blue book I could move to and reset the zero.
i have a more simple procedure that i use when it needs after origin lost
i go back to the piece i have on the table and put in spindle the measuring device that i use it for setting my G54,workpiece origin
i set up the 0 on the clock and the 0 on relative position display and go back to the reference with the values that i have stored in the work set page for my G54,becuase the values from there are the distances that machine makes to my zero piece.
Yes, I agree using known points works too. A workpiece bore or face.Quote:

When the tech is there, write down how he does it. It's useful to check from time to time.Quote:
