Where to get a laser height focuser?
I've been doing some looking around for a laser focuser for my retrofit. I haven't seen any info on them or where to buy them. Can anybody clue me in as to what they are, how they work and where to purchase one or at least where to get the parts to make one?
I'm using the lightobject Dsp Awc-608 and I would like to automate the height of my z table.
Thanks!
