Hi Frank,

There were mainly two reasons for your problem.

1 - The part was not part of a reference frame, which is required.

2 - The default approach and retract movement of 100 mm along the normal created a starting point out of reach for the robot.

I attached a modified version of the RDK station.

Hey Jeremy, I feel like I've thoroughly tried to do both these things (coordinate system for part & adjusting the approach/retract) and I'm still getting the no start point error. Am I missing something?

It's interesting because when I choose "select curve" and I click a curve I don't get the green arrows like normal. Before I added the positioner in this station I was getting green arrows. Maybe this is why it's telling me it can't find a start point? If so how should I fix that?

FYI I'm using the trial version on Ubuntu 18.

Hi rmoeller,

When you move the object to a specific place (Move geometry), you need to click "Apply move" before selecting the curve.
Also make sure the "Object position" is at Zero.
