The Shapeoko Forum

Thanks, Allen! A very useful document!

Thanks! That's a big help in trying to understand what is happening internally.

I've been trying to understand how the CAD and CAM software work. While learning how an SVG line is rendered onto a computer screen, I learned about Bresenham's Line Algorithm. I was really stumped when Bresenham is mentioned numerous times in the comments of GRBL's Stepper.c file. I tried to find i...

Looks like we need to start a list of MakerCAM issues! I think your second issue will be easier to track down than the pocketing problem. At least I can easily reproduce the pocketing error. That’s a start: pocketissueSS1.png Now a short update on SVG Arcs: I found another method for generating the ...

More to follow.

I would enjoy helping with your pocketing issue. I won't be able to do much until June, as I am heading from Chicago to North Carolina in a few days to visit my daughter. Just so you know, I'm very new to this and need to do research to get up to speed. I'm curious how toolpaths are generated, but I...

They look awesome!

Isn't it great when a plan comes together?

So, if 40 steps = 1 mm, then 1 step = 1/40 mm = 0.025 mm (approx. 0.01 inches).

Does that set the Shapeoko 3 pixel at 0.025 mm on a side?

First a quick recap: Available in SVG is the Elliptical Arc command. It draws a section of an ellipse from the CurrentPoint to an end point with the following format: A X-Radius Y-Radius x-axisRotation LargeFlag SweepFlag EndPoint.X EndPoint.Y Knowing the CurrentPoint and EndPoint and the radii, two...

The above is a great explanation. I found a couple of other tutorials on vectorizing bitmap files using Inksape. While the tutorials are intended for use with a plasma cutter, the vectorizing procedure is valid for use with Carbide Create. The best candidates for vectorizing are black & white clip a...
