Can't make heads or tails of my DRO, which is making troubleshooting a pain in the rear.
It's a Heidenhain VRZ 720B, 3 axis, on a mill. Looks like this:
I had a Heidenhain 2 axis before this and it was just: turn it on, go to work. This one appears to be more complicated.
I have not been able to find a user manual that actually explains how to use it.
On start-up, all 3 axis displays blink. I think this means they're not referenced? If I click through XYZ and hit the
REF button the blinking stops and Y axis will work but the decimals blink on X a Z and the DROs there don't count up/down.
But I can't get the REF light to turn off after that.
I think I've tried everything everything, even swapped X and Y scales, but still can't make heads/tails of it.
I get a feeling like I'm missing a step or setup parameter on startup. Tomorrow I'm going to try to clean the
actual scales themselves. Z is toast (broken reader head), but the other two look okay.. and after some combination
of button smashing they seem to read.
Any help appreciated.
This may be a moot point as I may need to 'upgrade' (to chinese) the DRO.. replacing the 3rd (Z) scale with
an original Heidenhain looks like it'll cost more than just going with a whole new set.
Thanks!
