Cutting thicker materials W/80w C02 Laser!

Hey guys, just having a play with some thicker materials seeing what it will cut trying different setting speeds and powers using my 80w laser! Thanks for watching!

My thought is the focus height is set for the surface. As it cuts deeper the beam widens. Have you tried to set the focus height so the focus point found be half way through the 12mm board? We obviously know the slightly out of focus beam cuts below the focus point, why not also use the slightly out of focus beam above the focus point. That would put the focus point deeper while still running at a reasonable speed.

Hi, yeh that would definitely be an option I know alot of people use this method when engraving large pieces as it leaves a wider engrave takes less time and is quicker but I’m not sure how that would go for cutting wonder if it would be a wider cut line may work good for larger cuts but not sure would be good on small detailed stuff but that being said theres only one way to find out I’ll check that out and see if that works 🤙🏽 thanks for watching!

You need a longer distance focus lens. To put it simply, the focused, or "cut" part of the laser beam is longer, making it easier to cut thicker materials. I'd use a 5" focus lens.

Thanks mate yeh I had herd this will have to look into getting one to try 🤙🏽

I had the same result with my 80w some months ago, it will do 10mm acrylic though. I think if you did 1 pass and then lowered the head for another pass it would go through.

[@woodendayz]

Yeh I have to agree on that mate it’s almost like it gets a certain depth and then won’t go any deeper due to the focal point changing, thanks for watching 🤙🏽

What setting did you use to manage to cut through the 10 mm MDF?

[@woodendayz]

10 mm/sec and 50% power will do 10mm mdf

Do yo do 101 training?
I enjoy your content 🥰

I've got the same 80w from vevor except I have a red laser head. Just curious what type of head do you have and what lense? Because I have my head pretty close to the material for it to cut. Cheers

[@woodendayz]

Hey yeh cool I’m not sure what type of head I have it’s blue and I think the lense is a standard 2” lense I have replaced from the one it came with as I messed up my alignment and ended up cracking the original so replaced with a cloud ray same size, do a ramp test to find your correct focal night my machine came with a small acrylic tag that was 15mm after I did my ramp test found it to actually be 11mm so I cut new tags to suit,
If your closer than say 10mm I’d say your all alignment is out so you may need to check that 🤙🏽 thank for watching cheers, Matt
