Having lived in china, and being a lot more trusting of their products, I immediately decided this was the route I wanted to go. From here I hopped on alibaba and used my vapor shop account (we buy our bottles and labels from aliaba) to get buying requests.
The request I submitted was very basic.
1300x900 worktable
150w laser
motorized table
red dot pointer
rotary tool
auto focus
In less than 10 days I had been contacted by over 15 vendors. One problem I ran into was that I had asked for an oxygen assist to cut very thin stainless (as I have seen 150w lasers do) this led to some very high quotes. I honestly think this should just be an extra feed coming in down below the lens to push in a gas to make a plasma? Should this optional part really make a machine run $3,000 more? Or am I missing something? Is it in quality of laser tube?
The quotes I was getting for a machine without any metal capabilities were in the range of 4-5k, the machines to add an oxygen feed usually came with a reci tube and ran in the range of 7-9k. Is it the tube quality that allows a 150w laser to get through 1mm stainless?
In the end I plan to use it mostly for leather cutting, it's a hell of a lot easier than making patterns for use with a hydraulic press every time you need to cut leather.
It's not like the purchase of this machine will make or break a business, worst case scenario it's a machine I hope to break even with over the course of its life, best case it pays off sooner than that. Beyond the questions I've asked here is there any obvious feature/option that I've totally overlooked? I'd appreciate any advice as I don't have any way to go and see one other than youtube.
