Hi all,
I have a Fagor Innova 20i-T Dro with Meister scales that I purchased several years ago for my lathe.
I have never felt that confidant in the accuracy and it has got pretty bad recently and I have noticed there are times when the scale is moving and the display does not change other than the numbers go blurry while the scale is moving. I have disassembled the scales and cleaned everything with alcohol, but it still has problems.
I recently purchased a cheap Dro kit from ebay so I could use the scales, but find that my Fagor takes a H15 D plug with 15 pins instead of the common DB9 pin plug.
I have the Fagor head set to 0.005mm but the X axis does not change the third digit, (5 Thousandths of a mm) when the scales move, but the Y axis does. I have changed the resolution for the X scale to 0.01 and it seems to be much more accurate now.
My questions are, 1. does anyone know the pinouts for the DB9 plugs for typical TTL scales and the H15 pinouts for the Fagor dro?
2. does anyone know of an adapter that can interface a 9 pin scale male plug with a 15 pin Dro socket?
3. Has anyone had any experience with scales becoming unreliable and not reading while moving?
4. What would cause a scale to work OK at 0.01 resolution and not 0.005mm Resolution? (the scales are supposed to be 0.005)

I hope I have given enough detail for a reply, if not feel fre to ask for more info.
