hal_gremlin shows strange preview if using gantry

Hallo,

if you use hal_gremlin as preview, like gmoccapy or gsreen do, and you do use gantry kins, you will see a strange preview.

As basis to check, I used axis / gantry sim with modified gmoccapy source code, to support gantry homing and jogging, so far it works.

To test:
Just take a glade panel and add a gremlin view to it, start axis with that panel and check Z view.

As I am not on my development computer, I am not able to attach a screen shot. Hope to be able to do that tomorrow.

Is anybody here to help to solve that one?

Norbert
