We have a roughly 20 year old Daito automatic saw, which is still a good saw. Anyway, we were having problems with our length of cuts and getting the lengths set correctly. I suspected a problem with the encoder, so I decided to open it up to see if I could find a problem. The encoder was corroded inside and it appeared that moisture had cause problems inside the encoder. I tried to clean the encoder and in the process evidently I finishing destroying the device. When I put it back on the machine the index shuttle would not locate but would only travel all the way back on the slide. So, I ordered a new replacement from Daito. The old encoder was a Sumtak LBJ-080-1000. They shipped me a new Sumtak/Heidenhain encoder IRS330-1000 along with 2 - 1 kohm resistors and a wiring diagram for the new encoder. I installed the new encoder as shown on the diagram and the index shuttle still does not locate. It appears that the machine is not reading anything from the encoder. Daito has suggested that they could ship me another encoder from Japan. I wanted to run this problem by you guys first to see if anyone had encountered such a problem. Is it common for a new encoder to be faulty? Are we overlooking anything that could be causing the problem? Any suggestions/advise you can offer would be greatly appreciated.
Thank you,
Gary
