- If you own a Chinese laser cutter this little series of videos about me learning how to use the free software provided, may solve the problem of trying to learn from a virtually unreadable manual.
I am nothing to do with RD Works, I am not an instructor and I am no expert. This series will document the essential bits of many hours of trial and error - Věda a technologie
i'm enjoying the versatility and diversions you're taking us through.
Appreciation.
Thank you for this and all your videos!!!
fantastic video russ!!! thank you for doing this and saving a heap of people headaches.. Have you got any experience with RD vision or the CCD camera attachment with the chinese lasers? i have CCD cant seem to get RD vision setup for it and there are hardly any callibration videos... much apprecaited!
Hi Idris
I did answer this comment but I note the answer does not appear on my summary page. Did you get and answer or did CZcams post it to a parallel universe?

HI RUSS
GOOD DAY I have been watching your videos in the order and i have noticed that you may have skipped a tiny detail about the interval option so would you like to tell me what is the interval option in the layer parameters does mean ? and what its effect ? what is the normally range for that option ? or if you mentioned that later in your videos kindly mention it .
thank you for your great help
Best regards
Hi Waseem
When you select SCAN you first have to consider what line thickness you will produce. That depends on the lens focal length, the speed and the power. Did someone say this was easy??? Typically you can assume 0.15mm. You could be engraving one of several different graphic types
1) Vector graphics as produced when you draw or created text in RDWorks To scan these an interval of 0.1 to 0.15 will work fine.
2)Bitmap graphics. When you have imported your picture to RDWorks. Add handles to your object and go to Handles, Bitmap Handle. A window will open and there you can see the resolution of your image. Lets assume it says 150ppi Set your interval to 25.4 divided by 150 =0.169mm interval. If you set the interval smaller then you will get overlapped burning if you set it slightly larger you will get occasional white lines through your image where the software jumps a line.
3) Dithered pictures (dot images). It is equally important to do the same as in 2) to check the resolution and set the interval to the exact pitch.
There is a LOT more to this subject but I will point you to a concluding eppisode

OMG !!!!
What a great information.

5 STARS YOUR VIDEOS.
Geday Russ Wayne from Australia. hope you can help me ?
How would i cut out an odd shape eg umbrella in 2mm perspex
Hi Wayne
Your question is a little vague but I am suspecting that you have loaded a picture of an umbrella (or something) into RDWorks to find that you can only scan it?
There are two types of drawing file. The first is a pixel file from a paint package, files like jpg bmp, gif png etc, the other type are vector files from cad or drawing packages such as Illustrator , AutoCAD etc which will be .dwg, dxf, ai svg etc. Vector files can be cut, scanned, dotted in RDWorks whereas picture files of ANY sort will always be imported and converted to grey scale. classed as bmp and only allowed to be etched.. If you wish to cut that bmp out you will have to generate a vector OUTLINE for it. You can do this in RDWorks by setting up a new layer and tracing round your shape with the bezier tool. The resulting line ( or perhaps a simple square or circle) will allow you to access the CUTTING parameter.
Hope that fixes it
Best regards
Russ
Thx
Is There a reason why you ran with no air assist on ? great tutorials :-)
+Daniel Ennis
Hi Daniel
Yes. Naivity and ignorance. This was one of the first things I cut. All my videos are live and rarely prepared and are basically a live and running commentary on my learning to use this machine. This is not a pre scripted set of tutorials so if you follow what I do you will make the same mistakes. This was about 8 months ago when I was very green and keen. You are watching me learning and making mistakes. I would never run now without air of some sort on, even though it my be turned down to very low flow. The primary importance of air assist in my opinion is to stop smoke and fumes getting anywhere near the lens. It is also important for keeping the cut channel clear, but that's another story.
If you haven't found them already there is a follow up series entitled RDWorks Learning Lab They run numerically from where I was at just after this first project to current. You may want to start watching that series so that you stay clear of some of the errors I made.
Good luck
Russ
