Invalid arc specification

I'm having some troubles with gcode files which were previously working fine with Goko 0.3.4. It seems that Goko 0.3.5 is checking the gcode and prevents it's execution if errors are detected.

I've got frequent invalid arc specification errors. Here is an example I can see in the editor:
G3 X28.533 Y-8.684 I3.08 J-10.974
X28.1 Y-9.038 I0.667 J-1.258
=> Invalid arc specification. Radius error: 0.024mm. Max allowed: 0.002mm

However I can't see any error in the gcode above (I've drawn the arc going from X28.533 Y-8.684 to X28.1 Y-9.038 and I do find a centre offset of I0.667 J-1.258).

Can you help me understanding the reason for the error message?

Thanks.

Hey, I'm having this exact problem, have any solutions been found?

I'm using a tinyg and Vcarve desktop and I'm having the same problem.

Hello guys,

Sorry for the very late answer, but you should be able to disable those check in TinyG under Preferences > GCode > Enable arc tolerance check
This being said, it will only disable it in Goko, but TinyG will still raise a warning. I'm currently implementing a way to ignore some warning raised by the board.
