Covers off?
Not yet I think. I'll start with the easy things and possibly then have a look inside the bonnet - but am going to be gentle for a while until I get more confidence in using it.
Yeah, I've read over the manual and the t-point add on manual. Funny thing is the manual suggests doing an automated calibration run (complete with pictures) for PA whereas the t-point manual suggests initially doing a run with 6 stars and then adjusting, then doing it again and iteratively getting more accuracy.
I'll do it the 6 star way first because it sounds easier.
