I'm new to CNC having built a 2-axis plotter driven by Arduino, CNC-Shield and GRBL 1.1.
I can draw a square.
I now want to draw a circle and have failed miserably for days.
I have googled on and off for about a week now and looked at dozens of examples. Not one of them does a circle. Not on my machine nor in any of about 5 different simulators I've tried. At best a limp arc, at worst straight lines or nothing.
Come on.
A circle.
Could someone post the GCode to do say a circle centered at X=0,Y=0 with radius 5cm?
Since I now believe it is impossible. Please check your work here:
