Hi,
I have a new CNC machine and need some assistance. I am fairly new to the CNC world - been dabbling in it for about a year now and just upgraded to a 24x36 machine. I've been running some tests, making basic geometric shapes and verifying the size. Everything had been ok for the most part except circles. Larger circles appear fine, but smallers circles have flat spots on the left and right of the circle (along the X axis). I assumed I had some backlash, but when I use a dial indicator to try an measure it, I am getting results of .003 or less on the X axis. Is that enough to throw off a small circle (.5" or so)?
Are there any other issues that may also cause this?
If it matters, I am using Vcarve Pro to crate the gcode along with Mach3.
Any help is appreciated!
Dave
