Just installed a JC900-2AE DRO on my Grizzly 4003G lathe and had trouble calibrating it. Found the good manual mentioned in this thread, which was a great help along with all the utube videos, but nothing helped my problem. The display was off by 30% or so, nothing in the set-up process helped. Finally figured out that I had left too much clearance between the read heads and scales. I had used an .008" shim between them just because it didn't seem right to have them touching. After closing that gap to barely touching the system worked perfectly. Just wanted to share in case someone else has that issue.
