Laser Cutting settings


#22

I used the vector mode with a SVG file.
At the moment I can’t test the file because I’m at work (not allowed to install Inkscape) but following file should work fine because only the outpath is used: Heart Vector Graphic
B/W or Grayscale mode will not work for cutting.

Please be sure you are using the latest Snapmakerjs Version v2.4.4-updated.1

anyone figure out what settings to use on acrylic yet ive tried so many things but all i get is bubbled up plastic


#24

I don’t think that you can cut acrylic unless it is very thin.
1600 mW and no part cooling will just “cook” the plastic at low speed and wouldn’t affect it with high speed.
“Professional” lasers for cutting have about 40-400 W water-cooled CO2 Laser power!!!

The laser cutter requires so much more testing since I don’t know the best settings for different materials.

Hi All, so i find a quick solution in focusing the laser, and it might differ from machine to machine but not with such difference.
Actually its quite easy, once your material is secured. just lower the lens until it touches the material with a piece of paper between your lens and material.
Then Zero the origin and lift the lens to a height of 34.8mm, and zero again.
That should be your 0 level then for engraving.
You might have to adjust it by 0.05 up or down.
HOPE THIS HELPS

Does anyone know if SnapmakerJS has a feature for setting multiple passes? Or do I have to do them manually?

@guzforster

With the latest version v2.4.6 you can do multiple passes. Downloads and Updates


#29

Anyone tried cutting acrylic? I’m trying now for the 3rd time with 4 or 5 passes at 100%, 80mm/minute, but it doesn’t seem to go through. Does it even cut acrylic?

Cheers

I honestly don’t know, but everyone I’ve heard that’s tried to do acrylic has failed. I thinks it’s possible though

@epoe thanks! I remember this video now. Maybe it doesn’t work with fully transparent acrylics. @Rainie could the Snapmaker team make a tutorial on how to cut acrylics and other specific materials?


#33

You have to add a layer of paint or tape so the laser light doesn’t go through the material without absorbtion of the energy.
You can try it with a black marker or a tinted film.


#34

Thanks! I tried that, but it seemed that it didn’t do much. It cut the surface of the acrylic and melted a bit the other end, but no matter how many passes, it wouldn’t cut. Maybe it wont works with solid acrylics, since the middle is transparent?

Hi, I recently got my 1600mW Laser module, I’m trying to cut trough a piece of wood 1,7mm thick and cannot accomplish that. I just read there was an update for the software to 2.4.6 and I’m trying it as I write, but the test I made for the right focus Z eight didn’t go trough either. I’m trying a multiple passes contour now to see what happens but it is like the laser doesn’t have enough power or something, it just can’t pass the piece. Is there any walkthrough to get a right setting and a straight good laser cut?


#36

Have you tried making the passes slower?


#37

Yup, slower, so slow as I went in manual mode, that is laser on and small steps with clicks until I cut something (a small square). I could see the laser going deeper as the time passed as it remained on spot… and then moved it slow again and again, awful cut, nothing tidy about it


#38

I cut the snapmaker contour, in four steps of 0.5mm, it worked, again no tidy cut but it´s the first time I can separate a piece.


#39

What kind of wood are you cutting?


#40

I’ve used poplar plywood but it’s not perfect. As soon as I have more time to play around with the laser I will try balsa wood.


#41

Does anyone know what is the software to use vector files to directly drive the laser?
