Engraving Basics in Wood, Acrylic and 2 Color Rowmark sign material

In this video I discuss the affects of speed power and air flow and how they if you just change air flow to your engravings how much it can change you look and reduce the contamination on your material. We cover birch plywood, cast and extruded acrylic and 2 color plastic sign material.
Wood results start at 2:55
Acrylic results start at 10:40
2 color Rowmark sign material 16:10
All engraving was done on a Nova 35-100 watt co2 laser
You will always want enough air flow to keep your focus lens cool. NEVER turn off your air flow compleatly! You will ruin your focus lens!
I purchased the digital gauge from smc pneumatics model number SMC ISE30A-01-N-L

@maggie9256 2 года назад

Very helpful. Do you have a video that shows how you clean up an engraving when there is residue?

@computercreationz 2 года назад

too much air flow is what generates allot of residue. make sure your using Minamal air flow when engraving. a quick sanding with 220 grit sand paper is the best. whipping it down with moistened rags or towns lifts the grain of the wood and makes it rough and then you have to sand anyway. skip the step of wiping and just sand.

Great video. Im struggling still with my 51/100 I have my power and speed close to yours with low as possible air pressure and it’s not clean and crisp. I also left the clear masking on should I take that off?

@computercreationz 9 месяцев назад

if you have clear masking are you engraving acrylic?? don’t use polycarbonate from big big stores or extruded acrylic for engraving . only use cast acrylic, remove the PAPER backing and very low air flow. thank for watching

@rgmtb 2 года назад

I'm sorry I'm a little confused. You mentioned air assistance was off but you are using air pressure. I'm 100% new at this so I'm guessing this is a silly question but I thought air assistance was air pressure? I was amazed by the differences you showed! So very helpful 👍

@computercreationz 2 года назад

I can see why you would be. In lightburn you have a radio button that indicates air assist on or off in each layer . You turn that off in lightburn when engraving if you have a Thunder laser because it really means when you have the air assist off in lightburn is means low volume air flow to the thunder. You never want to go without any air flow or you will crack your focus lens. Thanks for watching.

@relliott 2 года назад

Have you ever tried inert gas? We have a 4Kwatt Amada laser for cutting metal that uses nitrogen and I was thinking an inert gas would not promote the charring. I was going to try it out to see what it does on MDF and birch ply.

Can you do a video about when is best time to use CAST vs EXTRUDED?

@computercreationz 3 года назад

I touch on it a little in this video. If there is no engraving to be done I use extruded. If there is any engraving to be done I always use cast acrylic. Huge difference in quality when engraved!

@mr.e.6911 Год назад

Just came across this video, Curious about the digital pressure gauge. Do you have an installation video for this gauge? I'm assuming that you cut a hole in the machine next to the air assist, then just hooked up power and ground (12VDC?), then an air line to the gauge?

@computercreationz Год назад

On thunderlaserusa.com these is info on it. I see someone on Etsy has designed a housing for this guage to be installed on a thunder without any new holes.

@smbrown 2 года назад

Interested in more details about your variable air assist, perhaps a video topic?

@computercreationz 2 года назад

Thunder laser is one of the only lasers that have a dual air assist. you control it in your layers in Lightburn. air assist on or off. off really means low volume air. this will automatically switch from low volume air (engraving) to high volume air when cutting. this is very convenient and effective!

All right, this was likely quite expensive. Here's my answer to the question - get an inexpensive 15 PSI pressure gauge and cobble up something like this below; one possible - and very relative - improvement would be to get a more precise, multi-turn valve for airflow adjustment, but in my experience it is not absolutely necessary: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-OWRdnh18bqw.html Thx!

the flames are from lack of air flow, when using acrylic add just enough air flow to extinguish the flame especially on and type of acrylic

by adding a line just inside the cut you can make an illusion of a chamfer but because the laser beam is fixed at 90 degrees the 45 degree chamfer is not possible

High speed low power very little air flow. To much Air flow is your enemy. Your engraving should be very shallow.
