Be careful. I did this on my Tanzania everytime I calibrated it and finally broke the tiny plastic bit in the dial knob and it became unlimited.

Hah! Thats surprising, theres a pretty chunky piece of plastic in there. I actually ended up cutting those plastic bits off of another knob so that I could have unlimited grind adjustment (to grind really coarse and then regrind).
