Hi Ben,

We recently had some issues with our VS120 Slide Scanner stage which ended up being a problem with the comms card in the PC (we could push/bend the card and it would work).  We also swapped the cables around going into the stage to see if the problem persisted on the same direction or swapped to the other axis to eliminate a stage motor issue, other than that if you can find someone with the same controller you could swap in for a test that should help to narrow down the location of the problem.

Cheers
Mark

Hi Everyone,

I am having some strange problems with the stage on one of my widefield scopes and I am wondering if anyone has any suggestions?  Sometimes the stage seems to freeze and only wants to travel one direction in Y, but the opposite direction in Y is fine.    Driving all the way in the possible direction in Y sometimes fixes this.  Travel in the X direction is unaffected.
Other times the stage moves by itself in Y.  Both problems are sporadic, but now seem to be happening more frequently.  I am not sure if the problem is most likely from the controller, joystick or stage.  I have also occasionally started to get time out warnings about the shutter when I try to snap an image, which makes me think it is the controller.

I have a Ludl Mac5000 controller running a Ludl 99S106 stage with a MAC2 XY joystick and am running it with ZEN 2.3.

Offline/online responses welcome.


Thanks,
Ben
