Gsender won't read G3 command

I sat down to run a program Iā€™ve ran previously on G-sender and it keeps freezing up at the first G3 command. It doesnā€™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 itā€™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 thereā€™s no error, itā€™s probably not an arc endpoint issue.
