My first cuts (after calibration and focus setting) with my new 50W Chinese made laser cutter. Sometimes leave little bits not cut all the way through, but I'll work that out as I go.
So far so good!
Material: 5mm plywood.

wow that is really slow for 50w on such thin wood.

indeed, it measured at 29W. Replaced it with a 60W tube and is much faster now.

ye but my 50w can cut 4.5mm-5mm 3 ply birch twice as fast as that one pass. we tested my laser to be putting out actually 43w you probably had a bad tube to start with.

how much did it cost to upgrade?

yep, they should put the 50W in quote marks on ebay :-) When measured, it was putting out around 29W. After this video was made I upgraded to a 60W tube that measured in around 55... it's much quicker now.

Do a search for RDworks lab by Sabar Multimedia he goes very in depth but you will know more than you thought you would after watching him

Aww man, I'm sorry to hear that. They can be a bit of a minefield at first. This guy has a nice physical overview of the machine: esvid.net/video/v%C3%ADdeo-djgNTUiwaXQ.html There are some pretty good communities too. There's a facebook group called "Laser Cutting and Engraving" who are generally very helpful if you have specific questions. I'm also more than happy to share my experiences if I can help.

Hello! I am having trouble getting my laser to do any cuts. What did you do to calibrate it? Thank you so much. Any help would be much appreciated.

Hi there what power and speed settings did you use on this cut?

Thanks heaps, yes 3 days of persevering and then a mate with some fresh eyes Friday night with a few beers and we calibrated it quite nicely.... I'll have a read of your blog...yep got the 50W I'm actually really impressed with, trialled some 3mm opal acrylic and the results were awesome!

congrats on the new machine Andrew! Did you also get the 50W version? If so, 3mm ply should definitely be doable. Might just take some perseverance and twiddling. Alignment and the proper height of the part from the laser aperture is key. I made a blog post about the troubles I had with mine, and showed the results of a power test with the stock tube. The page is here: blog.holozip.co.uk/post/98759626856/chinese-laser-pain If I can help at all, feel free to give me a shout.

Thanks for the reply, I literally took delivery of it 3 days ago. The computer and machine are talking to each other fine, I spent 5 others trying focus the laser but having real trouble 'cutting' any ply. I had my first win today actually cutting 3mm acrylic and the cut and engraving was pretty good. The majority of my work will be cutting 3mm ply so I need to get it sorted.

100% and looks to be about 5mm/s (was a long time ago). Note the tube used for this cut was absolute garbage and only measured at 29W. Things got much better after upgrading to a 60W tube.

How far will the work table adjust down? No one seems to know.

@Laurence Bainsworth with the bed set to its lowest point, there is about 25cm (~10") of clearance between the bed and the laser head.
