My prior stage (proscan III) is doing some strange things when using HSC site generator. Firstly it was moving in the incorrect direction (I sorted this by transposing X&Y). More worryingly, the stage would appear to be moving 10 times further than it is instructed. I used a script to test 1000um of X/Y movement and the stage moved 10,000um!
Oddly enough, when using slide explorer for tiling it works brilliantly(!?)
