This has been a very interesting discussion and I’ve learned a great deal. I thought I’d finish it off by showing a graph of actual cutting rates (mm/sec) for GF Speed Settings for three different types of shapes (line, circle, angles) that are all 300mm in length. I don’t know how useful it is, but it illustrates many statements made by those participating in the discussion. Thanks for those! This is the image used for the testing:
I video recorded each print at GF speeds of 100-500. From the video data, I was able to determine the number of seconds for printing each shape at each speed. From that, I calculated mm/sec for each GF speed setting for each shape. Those results are graphed below:
The mm/sec for the line and circle were essentially identical. Printing the shape with all the angles (even though it, too, was 300mm in length) was significantly slower.
