Daid,
My avatar is a I3 derivative, but NOT an I3. As far as my new printer goes, its kinda like a ultimaker - with the X&Y on the same AXIS, however im using linear rail and rollers so I wanted to use 2 motors to drive it. Im having the skipping issue on fast movements and was hoping I could get that F9000 to change to F5000 somehow.
Probably a weight issue im trying to rectify with hardware.
