ok guys i finally figured out a pocket program and ran it. except for the offset
it looked swell running. i decided to run it again just to watch it. this was the next day so power was interupted. when i turned it on and tried to home it . it showed [y limit switch] . the table is almost dead center on x and y. looked under at switch and checked with meter . switches are good. any ideas would be appreciated.
thanks Dar

Yes, but is the 24 V getting back to the control?

I am still betting on this, it would explain it perfectly. Be careful if this switch is dodgy, it can cause a minor crash

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

I am betting that the y axis trip dog is stuck engaged. There are two switches in one housing, one is the y axis + - overtravel and the other is the trip dog. The machine only looks at the trip dog while homing, so it is possible that it stuck down the last time you homed, and now it homed in the middle of the table.

non flashing limit errors are software limits, not hardware[switch]

take the switch housing off, it is on the right, currently hidden by the x axis motor, and clean out the plungers so they actuate smoothly.
