Upgraded the spindle from the worthless 200w generic dremel to a 1.25hp Makita, all the difference in the world! Following vids are cutting through acrylic in 1/8" bites per pass with a very slow feed with the Makita turned down to its slowest setting. Right now the feed/speed settings are not optimal, it is spinning too fast & feeding too slow, so I will most likely be cranking up the feed rates & turning up the spindle speed just a hair. The power this thing has is awesome!
The cuts are a test pattern to verify accuracy & square of the machine. The cut accuracy was only off by 0.01" and was as close to perfectly square as my calipers could measure.
The belt setup is basic & needs a good tension system, which I am trying to design & fabricate now.
This will help the accuracy further & allow faster feeding speeds without loss of accuracy.
I am also working on a dust collection setup to keep the work area clear.
