DIY Laser levelling using webcam and laser level

[John McNamara]

Hi Kit

We are moving to the Hills outside Melbourne No Shed yet but room to build one. There is a big garage for now.

Thanks for the heads up on the IC chip, I would appreciate any feedback.
The levelling is needed to make sure the cutter head is truly vertical In X and Y. Before a cut is taken.
I thought for some time on this, It would probably work reasonably well without levelling, assuming the support rails were fairly straight. However reasonably is a word I would prefer not to use.

The way The machine will operate is to position the cutter head in X and Y before each peck.
Then using Joe's optical system position the Z at the wire before taking a peck down a known distance.

Regards
John

John,
I remember you mentioning something about this further back up the thread. I've come to realise that 'reasonably' is a word that fits more in my vocabulary than yours, or Joe's for that matter. Once I'm retired and settled into the new home I may well be making use of the sort of back-yard presicion that the pair of you are making possible for us mere mortals.

I've got a list of useful sites for software for that chip somewhere but not on this computer it seems. I'll try to find it and give you some links. Might be a few days though.
