BEAVER ROTATOR CALIBRATION FAIL

I just modify my old rotator and shutter with the nwm beaver borads. All the setup works perfectly manually ( means by the rocker switch ) on the rotator and shuitter. When i try to calibrate the rotator, the process start, the dome move then freeze with a strange message that even Jaime never saw ( Strange problem: try again?) this is not a very helping message ??? i then have to close beaver setup box and open it again to start over.

1- I tried (FIND HOME) after reaching the sensor, it freeze

2- I tried (MEASURE HOME) it makes almost a complete turn and around 1 feet before reaching the sensor, it freeze

3 - I tried (MEASURE ALL) it reachs the sensor and freeze.

4- I swap the boards from shutter to rotator and nothing change.

I think the problem comes from some parameter and not the boards.

is there anyone that had this issue ?

Thanks
