Just wondered if anyone else had made this mistake.
I mentioned elsewhere that I have just started using my new XI L mill.
I decided to reduce a bit of steel bar by 1/10" in 0.010" stages, just to get the feel of the machine.
The vertical scale is marked 0, 10, 20, 30 then back to 0.
Anyway, I did my ten cuts and measured it. Too thick. 'Strange' I thought. Then did another set of ten cuts. Same result.
After a bit of head scratching I realised that the scale has 36 graduations, not 40. each of 0.002"; giving 0.072" down per revolution of the scale.
I was incrementing down by moving the scale round by whole numbers, and there are only six graduations (0.012") between 30 and the 0 mark.
Please don't let me be the only one here to have done this.

Dave.
