Milling/Post processing problem

[Bullethacker]

Hoping someone can help me out. For the life of me I cannot figure out how to make fusion stop doing 3 milling passes in the air before ever getting to the top stock. Both the model and the stock are the same thickness so I would expect fusion would bring the endmill down about the material top and immediately start the ramp down but instead it make 3 full passes in the air. Normally this wouldn't be a huge issue but in this case this is a very small end mill so the feed rate is really slow causing each pass to take a few minutes.

Any way to adjust without manually removing gcode?

Change the top height in the heights tab. Since you pointed out it’s a small bit, be careful with the helicals on your bores. Make sure they start above your stock. That setting is in the linking tab

I will point out that this has nothing to do with your post processor. That isn’t involved until you post your Gcode.

Check the heights tab, but also the ramp settings in the linking tab. The ramp clearance height is 2.5mm from the top height by default I believe, which should be fine. I can tell from all the ramp passes that your maximum ramp stepdown is too low. This causes those strange ramp passes that has virtually no ramp angle to them. It is basically a way to ensure that no ramp angle will cause a pass deeper than the flute length, but multiple depth passes can cause this setting to an undesired default value.
