BenCutLaser / Re: Adobe Illustrator DXF Export Issue
« on: August 22, 2017, 01:58:41 PM »
I have not used Illustrator but can you export to DWG format? If so, you can just open that in a CAD file and save as DXF.
What formats can you export to?

Unfortunately I was able to export it to DWG but in LibreCAD I can't open the file and keeps giving me attached error.

BenCutLaser / Adobe Illustrator DXF Export Issue (RESOLVED)
« on: August 22, 2017, 04:28:53 AM »
hi,

I'm a profissional graphic designer but never used CAD softwares, what I'm doing now is design my cuts in Adobe Illustrator CC and export it to DXF. When I open the design in BenCut it appears to be very big while I'm designing in mm and BenCut working area is set to A4 size in mm.

I tried to save the design in SVG then convert it online to DXF then open it in QCad then save it again in different DXF file then open it in BenCut, but it's a long confusing process that my life as he**!

Is there anyway to be able to export designs from Illustrator to DXF and open it in BenCut the right way without all that long process?

Thanks

When cutting wood, the laser vaporized the wood, creating gas. The gas needs a way to escape. By raising the piece, it allows the gas to escape.

You will notice a big difference in your cuts if you do this. I just throw a few nuts under the piece and that works well enough, but others have fancier setups.

If you don't raise it, you will notice that most of the time, the laser will not cut through the last .5-1mm of wood.

Can't wait to see the model.

Yes this is the issue I'm facing right Now! Laser can't cut through in most times

I'll try it out and share the result

Thanks :)

is there a fresh air intake?

Also, evelate the matetial a few mm while it is being cut

Yes I made around 15 12mm holes in the front side of the box. When I close the box the exhaust fan makes enough pressure to make the required air flow to get rid of the smoke and smell.

About elevate the wood sheet can you explain  please why it makes a difference in cutting ?

Very Nice!!!!! How well does that air assist work? I kinda like that setup better than the air compressor constantly running.

It works very good I got rid of flames and and black spots

I'll post the design of the air assist box that I made and the fan model tonight

I've been working on this project for about 2 weeks Now, finally I finished it and I'm testing it.

Everything seems to work super

The wood I used is 18mm which was a bad choice since it turned out so heavy but it's ok.

I painted the inside with deep black colour to observe light.

I bought a powerful fan which is used in RC racing cars and designed simple box for it to use it as air assist solution.

Trouble Shooting / Problem cutting plywood
« on: August 11, 2017, 02:19:54 PM »
Hi,

I'm using BenCutLaser to cut 3mm plywood and it works fine when i test shapes in the application, but when i make large cuts on A4 size sheet it cuts parts and make it through the whole 3mm but other parts it couldn't.

I attached a photo for more explanation.

I have 5.5w GearBest machine.

In BenCutLaser i used speed of 300, Power 100% and 4 Passes.

General Discussion / Re: Laser Module Lifespan

Thank you Ross / Zax for the useful info, can you please post a link to a good quality module, I'm kinda lost between available options and offers.

dreamaker: business wise you would run the machine 8 hours a day (assuming that you have that much of work to run the laser at it's full power) which means ~3000 hours annually, about 2 to 3 years of work! Makes sense I guess.

The module costs around $300. The working hour would cost $0.0375

Hi,

I'm willing to start a small business and I need to study the cost of my machine consumption.

My question is what is the lifespan of the laser module ? mine is the same as this link:

I believe it's measured by working hours!
