Acu-rite Glass Scale Position-Trac Coding

[BR549]

IF memeory serves me someone already did it. The system uses a speacially marked scale that has a positional pattern encoded into  the scale ouput.

The system used a math calculation from the signal to decode its location. From a cold start all you had to do was start a slow move and as soon as it passed one of the signals you could determen where you were at then set that as current location and then you had to move to Machine zero and reset Machine coords.

OR something similar

I think is was on the yahoo forum years ago. I will try to find the info I have a copy of it somewhere here. SOMEWHERE

Yes! That is it. It would be great if you can locate it. I've been searching with no luck.

What model scales do you have?  Have you tried acurite support to explain the sequencing???

Once you understand how the position sequenced itself the rest would be easy.

I found part of the discussion it was for a differrent manf   http://www.heidenhain.com/fileadmin/pdb/media/img/571_470-24.pdf

But the process in Mach should be the same. The trick is in how you reset Mach's machine zero value so it represents the calculated encoder position values.

Still looking for the other discussion BUT i am afraid it went to an email discussion so it MAY be gone by now.

OOPS that was not a different MANF it was a different model.

Thanks. Those two links are  big help. The Heidenhaim link is enough to get me going. Acurite was no help, which I don't understand. How can they sell a product but not have a tech sheet explaining one of the features.
