Hi James

Hi James

really enjoying this subject James and learning from you for my own falcon 2 pro, cheers Paul

Hi again. :) I forgot something. The kerf is usually different between horizontal and vertical cuts. In my tiny designs I had to take that into account because my horizontal kerf is slightly wider. For example, using simple printing paper (80g/m2), in order to cut the framing for some windows and obtain wooden parts equally wide (mullion, transom, ... sorry, English is my 3rd language and I don't know those names but I mean the wood forming the grid between glas parts in a real window), I had to use an offset of 0.0375 mm but only horizontally. Since, it's impossible to set in the software, I reduced all cuttings by this amount vertically. A drawing would be a lot easier than words to explain this, sorry. But basically, if you imagine I have a squared window formed by 9 squares of glas parts (for some projects those squares have sides of only 0.8 mm), all distanced from each other by 0.125 mm (less is quite hard without simply burning the paper), I needed to increase this distance to 0.2 mm each square of the 3 vertical stacks of 3 squares. For the outer cuts, most of the times, this difference is not significant enough to be noticed because all the "laminated up" parts are in fact all "wrong in the same direction" and they finally fit together. I hope that what I wrote makes any sense. :D Cheers ! :)

That was really interesting, I have laser envy 🙂 as I only have a 20W Sculpfun. I'd be interested to see the results of a ramp test on the kerf to see if the optimal focus height is different from the factory recommendation and if the kerf reduced, not that kerf matters when you're cutting, as you said just take it into account at design stage. The only place it will probably matter will be engraving images, I'd imagine you would get better results on your bricks using 60W with the added benefit of much faster engrave times.

Great job on the video! I'm very impressed with the rather small kerf you calculated for this very powerful laser at all 3 settings. I would love to see you run some tests on 6mm (1/4") wood. I think you would want to cut with the 20W settings vs. the 40W or 60W if you're working on fine detailed projects like earrings, you would want the smaller kerf. Keep up the great job!

avid follower of you 3d printing (as been printing for a while now my self)... and now your laser cutting (just bought one of thoose) :) can i ask what thickness MDF, and stencil board?

Would you say this is a better alternative to a co2 laser with the same wattage. I have a 30watt but I’m finding it expensive to run and maintain and I’m looking for an alternative option to cut if laser buildings? Thanks

Hello ! :) Nice video. But I think there is one thing you did not go into. Probably because your machine is reliable enough and you did not need to. The vibrations when cutting at higher speed.
