Spurious "E0." in Gcode?

[john.sinclairS5U4D]

Why am I getting a "E0." in a simple drilling operation from Fusion360? I'm running a Tormach 770 with Pathpilot, and PP doesn't like it. The operation works fine if I delete it? Is this just a bug? Isn't "E" commands to do with extrusion in 3D printing?

Hi @john.sinclairS5U4D

Welcome to the Fusion 360 forums! If you are using the Tormach post processor to create your code, it looks like those E words are to dictate the height of the SmartCool coolant stream, if you have that option. If you don't have that option, make sure that the option for SmartCool is turned off in the post processor dialogue.

Let me know if that helps you out!
