At 2.8 if I load gcode at gremlin I can see white trajectories and gremlin automaticaly focus for it.
At 2.9 nothing happend only can see trajectories if machine moving.

Are you using remap M6? If yes, open ngc file without M6 command.

Yes Im using M6 remap and S remap. Today testing gcode without M6 and no tool calling. No succes still same problem.

Did you try simulation Gmoccapy?

Finally I found that problem is with remap code. If I disable remap looks like working good. I read some posts that variable <task> can help, but I dont know how to use it?
