Avoid These Laser Cut Mistakes: Mastering the Right Settings

[@Fossy35]

Thanks Roger. 👍

[@russellfay81]

Excellent video! I appreciate your sharing, especially at personal expense! And for people like me, who are just learning, these are valuable. I would, however, like to know how you decide between the settings that do work. What I mean is, do you go for max power and minimal time, minimal power for maximum time, or somewhere in between? What factors into your decision?

[@rogersshop]

Best "look". I also try to keep power below 90% when possible.

Lomger B1 30w for the win!!. Thank you roger for the video

[@brucecraighead8528]

Thanks for taking the time to show this , very helpful

[@bobbyrapp7723]

another very informative video. very helpful info for us who are just starting out.

[@Spirited282]

Cut tests are for sure a must. When just engraving you can still use the test as a general idea and just dial back settings? I still have much to learn

[@rogersshop]

Yes, I also run test patterns when engraving, just not this one as it would burn holes in the wood!

[@greenwithNV]

Fantastic video!

[@chrisciraldo4935]

I just ordered the b1 I’m super excited and have really enjoyed watching your videos and learning from you it’s like mr rodgers for lasers haha

[@rogersshop]

Simple project coming up shortly on the B1 as "beginner Project 16"

[@chrisciraldo4935]

Loved the 16project video still trying to figure out settings on the b1 my lightburn time and what it actually does is nowhere close

[@rogersshop]

@@chrisciraldo4935 Make sure you are set to mm/min and not mm/sec. Big difference! i only use mm/sec on my CO2 laser.

[@Fossy35]

Thank you for this Roger. Can I size the whole grid? I want to do a grid test for business cards. So I want to scale it really small.

[@rogersshop]

yes, to a point. Too small and you won't be able to read it.

Great job

[@mrgrinch61]

great SMART VIDEO Thanks

My laser dont cut 3mm plywood with speed 150mm/m and even with power 100% what can be the reason? I tryed all types of gbrl in lightburn

[@rogersshop]

My first two thoughts are proper focus and is the lens dirty?

[@iskrazpolski1715]

Im not sure about proper focus i have to check how to check this but half year a go was good :p I tryed to clean lens few days a go but its dont helped i will check tomorrow again maybe I made it wrong. Laser is longer b1 w30 so with 150mm/m speed and 100% power i cant cut 3mm plywood 😅 while I watched video where someone with same laser cut 5mm plywood with speed 1000mm/m... I will take your advice to heart and check it all tomorrow because now in my country is 00:30 oclock

[@iskrazpolski1715]

​@@rogersshop thanks you for the answer. Im not sure about proper focus because I dont know how to check this but I will learn this tomorrow and check. I cleaned laser lens few days a go but maybe I dont made it well so I will check it again. Half year a go its worked much more better :p but then it stay few months not used and now I wanted start using this again. I watched video where someone who have same laser "longer b1 w30" cut plywood 5mm with speed 1000mm/m and I cant cut even 3mm with speed 150mm/m..... its crazy for me. Thanks you very much for your advice i will take it to heart and I will check it tomorrow, because now is 00:40 oclock in my country 😅

[@iskrazpolski1715]

@@rogersshop i do it everything but its dont helped i think its problem with Lightburn not with laser, when i used another program "lasergrbl" i saw big diffrence, but this program is totaly black magic for me, so in lightburn i reset to fabric setting but it still dont helped but i see one problem and maybe this is the problem i tryed solution with type $30=100/1000 and $32=1 and when i type $30 there is a communicate "[MSG:Laser spindle on Pin:GPIO(32), Enbl:None, Freq:1000Hz, Res:16bits Laser mode:On]" maybe this is the problem?

[@tugbagoksu9070]

Hi Roger, I have a sculpfun s30 promax 20w. I make a cutting test but i can cutting max 10 mm/min %100 power for 3 mm plywood. I’ve ever cut for than 10 mm/min What’s the wrong, can you help me?

[@rogersshop]

Check that focus is correct. Check that lens is not dirty.

[@tugbagoksu9070]

@@rogersshop I think all of them is right but İ’ll try again. Thank you so much.

[@GokouZWAR]

Why don’t you use lightburn’s material test feature that makes these test grids?

[@rogersshop]

I have. they work too.

[@pbb1164]

Newbie here. I have a Longer B1 30 watt. After running my first Material Test, I think I inadvertently changed settings in the Edit Material Settings - specifically Speed and Max Power settings. Can you tell me what those values should be? Thank you.

[@ipemeitsi8767]

Please do one for Longer Ray 5 10W !! Thanks for your videos! :)

[@rogersshop]

You can run this grid on the 10W as well. Results will be similar to the Jicoda and xTool D1 I showed.

[@ipemeitsi8767]

@@rogersshop Thanks! Will do! I bought the Ray5 just a month ago. Keep up the good work on this channel. I have learned a lot.

[@niklaswennerstrand1010]

Why would you not use 100% power to get the fastest speed every time on a LED laser? On a CO2 laser the longivity of the laser tube can be prolonged by using lower power. But is that really true for a LED laser?

[@rogersshop]

Some say that running at 100% will shorten the life of the laser. I generally run 90-100% at fastest speed that still gives good results and have not found much degradation.
