Anyone tried to re-calibrate a Huepar laser level?
Mine had a bit of a fall resulting in it being out by a couple of mm per m. Couldn't find anything on t'internet other than only the manufacturer can calibrate, and looking inside it after disassembly there is nothing terribly obvious to make fine adjustments.
So, feeling I'd nothing to loose I had a go with some hot glue to rebalance it, carefully applying blobs to the 'high' side. Manged to get it within 1mm at 7m, which will do well enough for what I need.
Perhaps there is a proper way to do this, rather than my bodge...
