I have an EZ-Trak DX that started giving me a Y DAC overflow while doing the initial homing on the Y axis. This just started after sitting for a month without power up.
Looking around on the forum, it appears that this could be an encoder problem. I've checked the Y-home switch, and it seems to works fine based on resistance measurement. Motor runs Y axis in both directions OK. DRO readout looks fine when I manually move the axis, which I guess means the encoder is OK.
I've read here that you should ohm out the cables to the encoder. There apprears to be two pairs of four wires. Should there be continuity between each wire of the four, and to any of the remaining three wires? I'm not sure how encoders work.
Also, apparently a MARKER signal comes from the encoder. Is there any way I can check for this? I have a scope, but don't know what to look for.
Thanks for any help you can provide.
