Yes, thanks Christian for Estlcam. I had an older Arduino Uno (not an R3) lying around, unused, and with the instructions in the video above made it work on my old XP laptop – no electronics attached yet – ran Gcode etc etc. It did not seem to like working on my Win 7 64 bit pc – resetting Z axis to ‘0’ reset X and Y as well. So obviously need the R3 one with the pc.
I would welcome a direct connection from EstlCam to ‘Marlin’ boards – make gcode and ‘GO’!!
