So check this out. I ran some speed tests, this is the result of this gcode Cnc race! - #107 by vicious1 this Gcode is from the fastest cut I made on the Primo with an 1/8" bit video.
The Primo cut was a bit better but the Primo is also 14"x11"x3" cutting area, the LR3 is 48"x25"x3"
Very happy with this.
It is a worse bottom finish than the Primo’s, but both have some wavy stuff going on the LR3 pocket seems extra wonky on that one side I am investigating it.
