Guys, saw your posts, thanks! Brett n Greg, never mind.
Andrew, our issues are the same! Won't calibrate. Solution, dont use physical buttons on unit to go the full travel 'out' distance. Use software, in my case TSX, to electronically drive it out there, then shutoff power 10sec, then restart while pressing physical 'in' button. She starts calibration from there, fixed! If I use buttons to do this, chattering motor monkey!
Also, numerous US posts confirmed that 'stepsize must be 4 for Robofocus to calibrate',

David, good info re CCDSoft. I'm running TSX. Relevant to that setup with Robo?
