Hi guys, 

We have an ABB robot (6640, IRC5) and pellet extruder. We encounter interpolation errors when the extruder rotation value gets above a certain amount. The robot becomes jerky and eventually fails. 

Would it be possible to modify the post processor to periodically reset the extruder value after x degrees of rotation? Or perhaps split the export by sets of layers and stitch them back together?

If anyone has any ideas on our error, I am open to them, but we have talked with many professionals including ABB, none of whom have been able to solve it. 

Thanks!
Tom

Yes, you can customize the post processor to reset the extruder value. I assume you are loosing precision as the extruder value grows.

You should contact us by email so we can provide you with the source code of our default post processor for ABB controllers.
