New here and wanting to build a CNC laser cutter machine

[Gravatel]

See I was going go get the LS3020 pro for £1,125 but it doesn't have much depth to cut 110mm and I would need a better lens so in my mind I should be able to make a bigger version for cheaper surely?

I guess that that is a second-hand price? HPC appear to list them for about twice that price, plus VAT...

Mechanically, I'm sure that you could build the moving bits for a lot less. Last laser cutter I looked at was about A3 cutting area, belt drive rather than leadscrews, and all the moving bits pretty light weight with zero cutting forces to cope with, unlike a router. Simpler/cheaper slides and guides, etc. It's the laser tube, mounting and housing, optical path, power supplies, etc, that will provide the complications. Really interesting project, though, although given that you don't see build logs for them that often, a bit more challenging than a router or even mill conversion.

Also you have to remember your eyes as a little shot of bounced laser light won't do them much good ..Clive
