Laser problem 2—what kind of maintenance does a laser machine need?

Saturday, August 7th, 2010

Are there a lot of maintenance costs involved in using a laser engraver?

You may ask this question before you make decision for buying a laser machine.

Actually Apart from the laser tube itself being replaced every 3000—5000 hours there is virtually no maintenance. There is No belts, no bearings, no circuit boards. Nothing has had to be repaired on it. In ten years I’ve had it, I’ve replaced the focal lens, not because I had to, but I thought it was time and one mirror, because I thought it looked a little cloudy. The maintenance on these things are incredible. It takes so little effort, as long as you keep them clean. If you’re running a lot stuff that causes smoke, you want to clean it up and keep the machine clean so it runs good. The more you run it, the better the machine performs. The less you run it, that’s where you run into problems. If you have your laser sit for long periods of time, you’ll start to notice more problems with your laser tube because your gas starts to separate.

How to make PCB —Part 2

Saturday, June 19th, 2010

Last time I showed you how the Redsail min cnc router work on PCB. That is a simple video show. Then lots of friends ask me how can we make it exaclty like what you did in the video?

Actually we need 2 steps except the one with cnc rotuer

1. make your file–those drawings in software Coppercam. We use it, but if you have good kind of software. We will be gald to know it.

2. after making this file well, save it as G-code. Some friends will feel strange, cause normally after making file ready, we need to import it in artcam or type 3 or Ucancam to make toolpath. But for making PCB with Coppercam, the importing is not necessary.

Then you can import the G-code into our cnc router  RS-3636.

P.S: Redsail now make all cnc routers with USB connection. That means, we only make a toolpath in artcam or type 3 or Ucancam then import it into the USB handle controller, then we can control the router with that handle.

If you want to knwo the details about the job, dont hesitate to contact Redsail.

3.  Click “Imange” — “Mode” — “Grayscale”

4.  Click “ok”

5.  The picture is gray now

6.  Click “Image”— “Mode”— “Bitmap”

7. Please choose “Halftone Screen” in the “Method” option

8. Choose “Round” in “Shape” Option

9.  Then it will show like this—-looks photo is made by grating or mesh

10. Save it to “BMP” form
