I have Mach 3 ver 2.0, I has my machine runnig fine until the copter graphics card died. So here I am with a new CPU both old and new are dell's and now the machine homes fine but any go1 movements are jumpy. I downloaded a new verson of mach 3 and it seems to be running fine? But, sence i dont have a license for the newer version i cant load the entire file. I dont get it version 2.0 worked just fine on my old pcu???
