Laser Images on chc shark hd4

Postby sudo » Fri Mar 10, 2017 5:22 pm

Hello,

Im looking for documentation on using the laser module on the cnc shark hd4 to create an image.

I see this forum:

viewtopic.php?f=10&t=4753

Unfortunately, its for a different model. And the hd4 uses the pendant, not the control panel software.

Can anyone point me in a direction? Im using v-carve pro.

Thanks in advance.

Here you go. I set mine up today. It was easier than I thought it would be. I used this file and it worked flawlessly. I cut two projects testing this new feature out.

Thanks for the response. I do have this guide, but I dont think it has what Im after.

The guide outlines the process to laser engrave. But I want to do an image. Im familiar with setting the laser power and speed, but I would assume that an image would use varying degrees of power to create the shadows, etc.

I know I can take an image and bitmap trace it, but that seems like it will give shotty results at best. No where near the picture quality Im after.

Basically I want to print a picture with the laser, not engrave a solid image. I believe the advertisement for the laser engraver features an image of someones childs photo done on wood.

Thanks again!

I checked the catalog I was referring to but the image was associated with another laser printer.

Has anyone been able to use the laser engraver to get picture quality?

My aim is to get a nice 18 x 24 Norm Abram up on the shop wall. Something I think all shops need :)

Looks like vcarve photo might be what im after. I see the tuts on cutting Lithophanes. Will this work with the laser engraver as well?

PhotoVCarve is NOT suitable to use with a laser. The lithophanes require a ballnose cuter to create the 3d surface which gives the lithophane effect and the output from photovcarve will not modulate the power of the laser to generate any form of 3d surface. The PhotoVCarve style picture engraving will also not work with a laser as it relies on the toolshape cutting different widths of lines at different z depths. If the toolpath was output to the laser you would just get a load of parallel lines.

Good info Brian. Thanks.

So I guess laser photos are out of the question with the current setup? Can anyone from NWA give a definite answer?

From what I understand, the laser will burn a photo into the wood, bus it will be very shallow.
Once the photo is burned into the wood, you have to be careful to not sand it much, or you will sand it away.
Call Next Wave, They will talk you thru it.

Just pull down the software I wrote.. it generates a raster of most any image in under a minute.. no known size limit.

It is the fastest Laser raster file generator in the entire world!
& I bet it's easier to use than Paint Shop Pro by Jasc

http://nextwaveautomation.com/Downloads ... 0_Beta.exe
same code is in the old 3.0.. but this one has fourth Axis code included.

When you hit load file change the file type to any picture and have at it.
it does jpg and bitmap files.. but a few of the others listed were not actually available.
