Hi, I have written a code on Nc Viewer and it works perfectly, using same code on OB control doesn't cut circles. Why is this does OB not recognize the I for full circle? I am stumped,
Can you attach your code so that we can see it? Do you get any error messages? If so, what [exactly] are they? Are you using relative or absolute offsets for the G2 command? There are different requirements for the arguments following it - see section 5.1 in the linuxCNC documentation: G-Codes
the line for the code is G02 I7.5 everything else worked fine just this line doesnt want to work. im new to the codes and files so yeah im learning.
Grbl doesn't like Full Circles. Do two half arcs: G02 Full circle Mainly though, don't bother writing gcode by hand, use a CAM, and make sure its Grbl Compatible: docs:software:overview [OpenBuilds Documentation]
GRBL only uses relative I J K offsets, LinuxCNC can use absolute or relative. also, although GRBL can do full circles, it does not always work, better do restrict arcs to 180 degrees
GRBL wants X Y I J on every G2/G3 line. writing your own Gcode is an excellent vehicle for learning Gcode, but using a CAM for production code is much more efficient and less prone to crashing the machine horribly (-:
