That’s what I’ve come to realize. I’ve been using chatGPT to help me as well. It gave me a line of code to try in my post. I’ll try that this morning.
if (isCircle) {
// Get the center and radius from the circle definition
centerX = circleCenter.x;
centerY = circleCenter.y;
radius = circleRadius;
// Calculate the start and end points for half circles
startX = centerX + radius; // Starting at the rightmost point
startY = centerY;
endX = centerX + radius; // Ending back at the starting point
endY = centerY; // Y remains the same
// Output the first half-circle
output("G03 X" + centerX + " Y" + centerY + " I-" + radius + " J0");
// Output the second half-circle
output("G03 X" + startX + " Y" + startY + " I" + radius + " J0");
Give it a try. I suspect the output will be wrong, but it may get you past the “No Axis Words” error.
I also suspect the line output here will give you the Circle Endpoint error.
I’m curious why it starts at the rightmost point on the circle. What if the circle doesn’t start there?
Or is this just for cutting full circles that aren’t connected to other moves?
Also curious about calculating endX & endY, but not using it??
I would modify to
if (isCircle) {
// Get the center and radius from the circle definition
centerX = circleCenter.x;
centerY = circleCenter.y;
radius = circleRadius;
// Calculate the start and end points for half circles
startX = centerX + radius; // Starting at the rightmost point
startY = centerY;
endX = centerX - radius; // Cutting to the leftmost point
endY = centerY; // Y remains the same
// Output the first half-circle
output("G03 X" + endX + " Y" + endY + " I-" + radius + " J0");
// Output the second half-circle
output("G03 X" + startX + " Y" + startY + " I" + radius + " J0");
}
So the code that Chat GPT suggested didn’t work. It’s too complicated for my post. Eventually it suggested this
EX_CIRCLE:
: G17 CIRCLEDIRECTION X* Y* Z* I* J* F*
and now esprit outputted this g-code

Which is pretty much what you said was the problem. Again, I’ll have to wait until I’m home to actually try it on the Machine. I think I’m finally in the right direction.
