Gsender won't read G3 command

I sat down to run a program I’ve ran previously on G-sender and it keeps freezing up at the first G3 command. It doesn’t error out, it just idles. I tried opening up the tolerance for arc moves from .002mm to .005 mm in the firmware but still having the same issue. Tried the same code in candle and it’s running with no issue.

@DIJANAB89 Dee: You say that this same file ran previously, so the question has to be ā€œwhat changed?ā€. Clearly something did or it would run successfully now.

Can you share the gcode? If there’s no error, it’s probably not an arc endpoint issue.
