Problem with GRBL post processor and G19 command

[nectarietotan]

Hello!I recently aquired a Vevor CNC3018. I'm having some problems when executing the GCode,  I create my GCode in the Manufacture tab of Fusion360, but there is a problem, the board of the CNC gets stuck when executing G19 command, it doesn't follow any commands and the only way to fix it is to reset the board or to powercycle it. This occurs on some shapes for example on a simple rectangle G19 is used, but on a plane rib there is no G19 used and the CNC is working perfectly.That's strange because on simple shapes I encounter problems, not on complex ones, I'm exporting the NC code using the GRBL post processor.Is there any fix to this problem?

Im not sure why you'd even have ZY plane movements in your code.

Does it output properly with this attached post? How is your model setup in the Manufacture Setup?

Well I don't know why it needs G19 for a rectangle.... I did cut a plane rib and there were no problems that s strange...

I'm guessing the G19 is being output when you have Vertical Lead-In/Out radii defined. If it's approaching purely in the ZX/Y direction, a G19 will be created and then you get an G3 I/J move. If it's approaching at any other direction (in ZX/Y) it will linearize the moves and no G19 is created.

As a test, could you disable the Vertical Lead radii on the last tab of your toolpath? (just set to zero)

Where would that be located? In the setup or in the 2D/3D operation?

In the operations
