@@md.asrafulislam1436 if you click the layer that you want to set, it should have a pop out window and you can swt min and max there.

@@RamiShariha what machine are you using and what what are your settings? Are you sure you’re using Delrin and not HDPE? Delrin and HDPE look almost identical but HDPE melts like wax when its engraved with a CO2.

@@laserillusionstech Thank you for the reply bro, I Am using a 130w laser machine, my setting was 100mm/sec speed and power ranges from multiple tries 10% up to 40% it either melted the sheet or it didn't engrave at all ! i bough a Polyethylene Sheet Hard Plastic Sheet Board from amazon. is that the right thing?

@@RamiSharihayeah youre using HDPE which is High Density Polyethylene. That will just melt like wax when engraved. You need Delrin (also known as POM or Acetal).

@@laserillusionstech Thank you for your help, just bought an acetal sheet for testing, and hoping it will work out, thank you so much for your help <3

Thank you! ❤

can I ask what's your laser max power is ?

one more what's the material thickness you are using ?

@@AbdulrahmanLehyaniMy laser is a 50w co2. And the delrin thickness is 2mm :)

Please see pinned comment.

Thickness generally doesnt matter when just engraving. It only matters if youre going to cut the acrylic with the laser. What matters more is that you use cast acrylic and not extruded. That being said, I usually use 4mm cast acrylic for most of my acrylic engraving projects since I have a 50w laser and anything thicker would need power higher than 80% or multiple passes..

Yes its CO2

Poland. My wife is polish :)

such a lovely country @@laserillusionstech

Agreed :) This is a pretty old video. I make less movements on my videos after this haha. Thanks for the feedback.

Thanks for the feedback! :) Appreciate it. Ill release a parts list for the frame and panels soon on my facebook page. The extrusions are 2020 extrusions from 8020.net. Initially I was going to use 4040, but I figured that 2020 would do just fine if designed correctly and its cheaper. For me personally, I just use my controller arrow keys to move the head to the position that I want when the machine is on, so I dont need any toggle to disable the steppers. I usually try to avoid moving the gantry manually with my hands when the machine is off since the stepper will work as a generator if you move it very fast and could potentially damage some things due to voltage spikes, although it is very unlikely... I also have flow and pressure control already on my air assist lines using a pressure regulator and a needle valve. As for the digital temp gauge, the chiller already has a readout of the actual water temperature, so I didnt need to add any other temp. gauge on the machine. And I dont currently use a rotary anyways, so I didnt think of adding a "quick switch" wiring for it, but will definitely do an upgrade when I decide to get a rotary in the future. As for the red dot pointer toggle switch and the wireless use of light burn, those are very good ideas as well. Will definitely need look into those. Thanks! ❤

03:50 to see air assist flow control 06:17 to see digital temp. Readout on chiller.

​@laserillusionstech that is the point of the switches for the steppers. It allows you to manually move them without worry of building a charge. But again personally find it useful in circumstances. And yes I know the chiller has that info, but for me it's nice to have all in 1 spot, and unless I am wrong, you cannot wire the chillers guagers into the dsp ? I don't own a chiller I built my own, so I only know what I've read. And yes I figured you had the flow assist on the lines, it just comes down to ease of use and access. Everyone has what works for them :) just sharing. You definitely have one of the better designs I've seen. I like the idea of a single unit instead of a case built around the laser like I have.

@@Protocol-Xyeah for the chiller, it can be wired directly to the dsp. You can set the alarm on the chiller, and if your temp. goes beyond the setpoint, it will send a signal to the dsp and it will disable the CO2 power supply :)

Seems a comment got lost. Sorry if this is a duplicate, but check out led strip diffusers. They have ones that fit 2020 and make a huge difference over straight led strip. If you are interested, you can also build yourself an attachment to use this as a galvo marking laser . I've done it on mine, it is still a work in progress, and a bit costly ~ 800$. It works pretty well, but I need a better alternative to a printed attachment due to the heat that mirrors build up. You would need to make sure your current setup has z clearance for a galvo lense focal length though. Could be an awesome video to see.

As I said in pinned comment, this video is 3 years old and is outdated. I made this video when lightburn did not have a great way of editing photos for engraving and imag-r was the easiest choice for people that did not have photo editing experience.

Hehehe. Sorry ive got adhd. Tried my best not to do that on my videos after this.

Either turn your air assist off, or use a nozzle with a larger hole and minimum air assist. You can also use a dc fan blowing parallel to the workpiece to clear the debris during engraving, as seen in my video.

@@laserillusionstech thanks, I will give it a try. Is there anything I can do to get rid of the black dirty bits after engraving, I’ve used rubbing alcohol which removes most of it but you can notice a little bit of the dirt being stuck in the engraving which doesn’t come out even with rubbing alcohol.

@@TarunSonga Im assuming youre using a CO2 laser right? Those small little dots are hot splatters while youre engraving. When they land back on your acrylic, it stays there. Add a very thin layer of dish soap to the acrylic right before engraving. Then when those splatters land back on your acrylic sheet, it will automatically cool, and you can wash it out afterwards with warm water. Dont use rubbing alcohol to clean acrylic. Sometimes it creates clouding and micro-cracks. Only soap and water. Cheers!

@@laserillusionstech I’ve got a few more questions if you don’t mind, I’ve messaged you on instagram.

Yes that is correct!

Thanks. I applied the soap on the engraving side.
