I have a 2001 Eztrak that worked fine before I moved it to my garage, now the x axis will not home but just slowly moves till it alarms out (X DAC underflow). Ive swapped the X and Y servos, no change. What can I look for?? Also does anyone have a wireing schematic.

Thanks

Are the drives turned ON when they drift?
Usually a drift occurs when you lose the position loop and the balance of the drive is a bit off center. But a DAC underflow means that the control is seeing the encoders and they are moving when they are not supposed to.
I would be checking the 12 VDC which presence turns the drives off.

The X axis drifts when it tries to home but it will not home before it alarms out. I`ll check the VDC thanks.
