I have a few posts on here about the various issues i have had with my supermax retrofit. Now i am focusing on the dugong drives. i am hoping some users here are using them and can help. I am using the c11 bob and the hdbb bob. How do i tell mach where the encoders are and get some feedback on the screen? How do i use my handwheels and use mach as the d.r.o.? Another issue i am having is that if i am calibrating my axis steps in the settings mode, if i change directions it seems to show no backlash in one direction, but about .005 in the other. This is consistant. i dont know if its a dugong issue or what? i dont think i can adjust backlash in one direction only .......... can i?
