I have been trying to finish a particular part of a job and I have been stuck for 2 days now. Every time I machine a specific section (see attached picture) I get an error saying “ERROR (2): GRBL ERROR: The motion command has an invalid target. G2, G3, and G38.2 generates this error if the arc is impossible to generate or if the probe target is the current position.” It had done two other sections of the same shape with no issues. The tool path is a 3D adaptive with rest machining from a prior operation (.25" flat end mill) with a .125" flat end mill. Not sure what other information I can give so if anyone can help just ask and I can give whatever info you might need.
