I couldn't get G2/G3 to work.

Let's start with what a Delta thinks is clockwise vs counter clockwise.

What does it, consider what lets say when looking down at the print bed from the top

We know 0,0 is in the center

-X is to the left, +X is to the right

-Y is to the front, +Y is to the back

My assumption is that for clockwise, it would go: back right quadrant, front right quadrant, front left quadrant, back left quadrant.

But I couldn't get a movement with G2 for clockwise, G2 for counter-clockwise did move from right to left along the front of the bed.

But I kept getting that the movement was out of the printers print area

Running on a Delta with a 284 mm printable area.

So in a CAD drawing, I drew a circle smaller than the printable diameter of my bed. I drew a line from center to the circumference of the circle. I mirrored it and then measured their distances from the origin in X and Y.

Moved to the first position,

G1 X-15 Y-139.79 F1800

Tried to move to the opposite side along an arc,

G3 X15 Y-139.79 I0 J-140.59248 F1800

It kept giving missing I or J parameter

I tried G3 X15 Y-139.79 R140.59248 F1800 and got missing

It kept giving missing I or J parameter

Then I tried

G3 X15 Y-139.79 I0 J140.59248 R140.59248 F1800

It moved, but didn't appear to complete the arc, position in X was something like 1.6

So I'm a little lost how it works, if you do G2 X15 Y15 should your head start at x15y15?
