Need Help!- Parameters on a 21T

[wganders]

We lost all our parameters on our Lynx w/ 21T Fanuc controll. We've restored them but now the machine will lose part zero when the machine is turned off. Every morning we have to touch off tool one otherwise we'll scrap the first piece.

Is there a parameter for remembering the work offset on power off?

Thanks,
Wganders

Are you setting the Work Shift or G54 Z? are the previous values gone, or is it just not picking them up?

I've come Across this before try this
1) set parameter 1815 (apz) to opposite of what it is so either a 0'or a 1.
Leave parameter write enabled on and power down machine
2) rehome machine then turn parameter write enable off
3) cycle power 1 more time and home machine.
Your finished
let me know how that goes.
