Re: MakerCAM - Issues with Circles (Google Chrome, Mac)

X, Y, Z, I, J and K are coordinates. They're in millimeters, and it makes no sense to preserve precision beyond one micron. Three decimals are plenty, but if you want four, so be it, as long as your lines are less than 50/70 characters long. G-code is relatively easy to read. It consists of command...

Re: MakerCAM - Issues with Circles (Google Chrome, Mac)

From the wiki line lengths (number of characters/line) maxes out at 50 in old versions 70 in newer but this file has lines as long as 87 characters majority of line are beyond 70. The positions are calculated out to 14 decimal places which is higher accuracy than the size of an atom, usually 3 deci...

We've seen the circle/stairstep problem before, and it turned out to be very long lines, longer than GRBL could handle, so it ignored important parts of them. If you could post your actual G-code, it could be helpful. Hopefully this file attaches correctly; if not I'll find somewhere to host it and...

Re: MakerCAM - Issues with Circles (Google Chrome, Mac)

What does the G-Code look like in a previewer? Here's the gview for reference. http://i9.photobucket.com/albums/a64/Droperer/ScreenShot2013-04-29at83806AM.png This is exactly what it looks like when I visualize the 'nc' file in UniverstalGcodeSencer-v1.0.6. When I press 'send' to start running the ...

MakerCAM - Issues with Circles (Google Chrome, Mac)

Everything seems to be working well, except this one issue. For whatever reason, when it's drawing a circle the X and Y axis are not moving at the same time. The X axis moves, then the Y axis moves, then the X axis moves, then the Y axis moves, and so on. This makes the circle look like a 'stair-ste...
