I'm in the process of converting a small CNC machine to a Laser engraver. My question is,
Is there a Gcode command to turn on and off the Laser? I can move the Z position up and down to the focal...

After I draw on Qcad then take over to Kcam to convert it to Gcode I end up with a lot of useless operations. Like jumping all over the medium I'm cutting ( not in order), not to mention going up and...

Thanks Gerry,

Hello to everyone in the group,
A few weeks ago I purchased QCAD and I am very satisfied with the program. I use KCAM4 as my CAM program. I use the combination QCAD/KCAM4 for CNC engraving. I...

Hi everyone,

I am using a Sable 2015 mill/engraver, Kcam software on Windows xp. I have had this setup for 2 years and it has worked very well for me.

My first question is:

About cutting...

Thanks for all your help fordav11 on this program. The program is good for a quick multiple line sign or tag where you don't need a special font. For the type of engraving I do, I use "DeskEngrave"...

I want to thank everyone for chiming in on this. To answer fordav11's question, they a have a data folder that the program looks individual letters and numbers for each cut. For example for the lower...

I am running a Sable 2015 and k-Cam4 software. I think my main problem is, I don't understand all the ins and outs of the command G02 and G03. I seem to be relying on conversion programs...

I tried to write a g code program to make a disk out 0.065" aluminum sheet. The disk is 2.75" in diameter with a .500" hole in the center. I've tried to get some quotes from several Jobbers and they...

I am looking for a g code program to make electronic panels. I've been using DeskEngrave for the lettering. First I have to load the new label manually move to the new location reset the start point,...

Has anyone had any experience machining extruded Plexiglas stock? I've machined cast Plexiglas which lends well to machining, but the extruded type turns into a gooey mess when when the end mill cuts...

I'm kind of in a quandary. I need to engrave, chemically etch or laser cut three types of radio dials. These dials (see attached) are not made any more and when you find them everyone wants a premium...

I think you misunderstand. This unit attaches to the bottom of the top panel (see attached). I have sold 3 of these for $80 a piece and have got the manufacture time down to 5 hours. The picture is...

The key here is authenticity(NPI). Some have used a Micro-switch, but if you are making a replica it has to look like the original.

Here's a picture of the one I produced. The base is made of Delron instead of Plexiglass.

Thanks for responding,

If the average Ham were to do this they would probably use a drill press and a file. It takes me approximately 10 hours to complete one of these keys using a Milling machine...

I am in the process of reproducing small telegraph keys. This key was used in a WWII spy radio that a lot of ham radio operators are reproducing. They are building everything except the key because...

I have a JDM 18 Jet Mill / Drill that I want to convert to CNC. There are several questions on the conversion that have me in a quandary.
