I have been running my DIY machine now for about 3 weeks, with great success. I have cut some parts using Mach and like what I see so far.
My question regards IPM, etc. I have the FET3 Hobbyist setup from Stepperworld, using the supplied p/s which is a PC supply. The motors are 110 oz. I use 1/4 20 threaded rod for the screws. I get about 10 IPM average and wonder if that seems low to anyone but me.... my router is a generic import 1/4 hp trim router and/or a dremel 300. I made some prototype parts from 1/4" hardboard that came out great, but the cut time was about an hour. The cuts were made on Mach using a 2-D g-code file and the multipass wizard. I set the cuts at .04 per pass. I have watched videos here and there and wonder if I might have something configured wrong. The only thing that keeps me from thinking so is that my parts come out perfect as far as the cuts and the dimensions. Am I cutting to shallow on each pass? Or is my machine slow because it has 20 TPI screws? Any input would be great.
Thanks,
Buddy
