6mm cutting
« on: August 01, 2017, 08:53:03 PM »
I am sure I already know the answer to this.

Do you think there is any chance to cut 6mm material such as mdf with out lasers?

I would use air assist but do not have a z axis. Maybe try to do 3mm then refocus and go again?

My experience has been that 3mm is about the thickest you'd want to cut using our laser diodes.

Depending on how big you cut out part is, it could take a while to cut 6mm. And I do think you'd need a z axis to do it.

I converted my 3D Printer into a z axis capable laser printer to test BCL's z axis code. While I finished my coding to support a Z axis, I found out, cutting wood thicker than 6mm, while it can be done with a z axis machine, in reality, it's a laboratory exercise at best.

I wouldn't want to really cut 6mm or thicker wood because of the time it takes. While testing my z axis code in BCL, I was able to cut through 9mm thick wood -- BUT -- using my 1.6 watt laser, it took over 150 passes. Not really something I'd want to do outside of the test lab.

Perhaps the 2.5 or 5.5 watt lasers might be able to cut thicker woods faster, but I didn't test those.

Thanks for the input Ralph. I was thinking something along the same line, but just needed confirmation.


I have a design I want to try, but requires 1/4"(6mm) wood. I figure I will just use the laser to lay the template down on the wood and have fun with a jig saw and drill.

Yeah, I think you've got the right idea there!

Thick material is tricky. I did once cut 10 mm MDF by doing about 5 mm from two sides. You need good X- and Y-stops for this, so the piece is exact on the correct place and mirror the design.
It took a very long time in total. I did run my laser for four days.
I am now thinking of buying a CO2 laser from buildyoucnc.

Bert, do you have a link to that CO2 machine?

>I believe the price is also OK.

I guess I'm not as rich as your are Bert. $7k for a kit is out of my reach!
