DIY Laser levelling using webcam and laser level

[devmonkey]

Joe,
That's beginning to sound as fiddly as using the traditional West Systems 105/209 epoxy leveling method with more potential for errors. Gravity never makes mistakes. What do you see as the advantages to your proposed method?

Hi Kit,

I do have a pack of 105/209 here for this machine, trouble is the temperature in the UK in my unheated uninsulated garage is about 6 degrees, so would have to wait until summer.

I was also hoping we could improve upon the accuracy of epoxy, from the measurements taken in this thread:

and Jonathon's build here:

It appears with epoxy 60um (0.06mm) peak-peak error is possible, I think we can do better than this with the laser and also not have to wait 2 weeks for the epoxy to cure. It might be possible to perform the process I described above in a couple of hours. 0.06mm is 20 pixels on the image sensor to give an idea of comparable resolution.

Cheers, Joe
