Compressed air makes a huge difference. Would cut down on passes and how much power u need to use. U need a small compressor that can push out a constant 15psi. You will be amazed at the difference..
I recommend you change to Lightburn software, I know it's not free but well worth the upgrade. For this particular job here you could (for e.g.,) use a function it offers called 'Print and Cut Wizard' which allows you to remove your workpiece and then replace it and get it perfectly realigned for another pass. That's just one of a vast number of other advantages Lightburn offers. Also, if you're not using air assist (and note that the fan on the module isn't really much help), then clean your lens regularly with alcohol and a cotton bud because it will get fouled up with soot etc., and that really reduces the cutting ability due to the spot size increasing (it gets fuzzy due to the dirty lens). If you are planning on cutting much thick stuff you would be better using a laser module with modified beam focus (like the Sculpfun S9) which has a longer depth of focus and smaller spot size. For the money it's better than struggling with lots of minor mods to the setup you have now - and you can always swap between them anyway. I also have the Neje 30w but have the S9 on order..
Hi Chris you sound like you have quite a bit of knowledge in cutting black acrylic with sculpfun s9. I am looking to buy one for this purpose. Are you able to share some photos of work you have done in black acrylic on the S9. Many thanks
I wonder if lowering the laser after a couple passes each time would make it faster? I would think by the time the laser got deeper it's losing it's focus?
Hi I blocked one of those I love it I have my I have my laser 20 mm off is 20 mm off the base of The table but when I use white foam board it's not it's not cutting all the way through or or it's melting the phone some the phone so much it's unusable what are what are your measurements please for focus on for focus on phone board
i did not have any luck with foam core board. Very flammable! But then sheets of craft foam did ok. I don't use a set distance from material to laser, just try to get as small a pinpoint as possible.

I loves the paper gauge that's a great idea
Hey thanks, great use of those fortune cookie papers!
valiant effort.
Hee hee, thanks. Not gonna lie, there may have been some blood, sweat, and tears on this one. ;)

Hi and thanks for the great tips. You're right lightburn is great, I finally did try it. Will have to explore the Print and Cut feature!

Ah that's a good idea. Would have to be very careful not to bump the acrylic, but worth a try!
when u getting a better bed? say honeycomb or grate ? cardboard is so uneven.
so true, i bet that would help a lot!

So the answer is simple don't make straight 90ﾟ corners just do curves
yeah it's so cool, i would never have known there would be such a diff!
