General Mach Discussion / Re: Cnc code for laser switching

Hi

Thanx for your reply.

Ok, i have looked at the sample you attatched. It makes sense. I suppose Cambam cannot or does not have the ability to insert these codes automatically as it was made mainly for a rotating chuck with cutter, so its a manual process with notepad or a cnc code editor of trial and error if i`m going this route.

My next question is the laser speed/intensity. I have changed my laser to work with 0-5volt with the "DC-03 DigiSpeed GX V3 (DC-03)" from Homanndesigns.com.
Before it was using the "H" & "L" inputs on the laser power supply. I believe its part of the pulley speed setup, but i dont understand  how it works. I know one must use the "S word" for adjusting the laser speed/intensity. One can make adjustments in % like 30% , 60% etc, so 90% will cut right through the wood and 30% will be good for engraving letters/text. So as you can see i have an idea, but to set it all up in Mach3 and the cnc code file is where i fall out the bus. 

Thank you
Andre

General Mach Discussion / Cnc code for laser switching

« on: June 06, 2012, 10:10:31 AM »

I have read hundreds of post bout the M11P1/M10P1 codes. I understand what it is suppose to do, but since i`m a newby, i have difficulty understanding how all this fits into a cnc code file. My previous experience was with a chinese REDSALE laser, which broke down. The machine is nearly on its way back from the scrappile 75% complete with new hard/software. Can someone please explain to me in a very simple way how the commands will look like in a very basic cnc file like this:
I have 2 circles one 100mm and the other 200mm across. So my way of understanding in normal txt is below :

*switch laser on* (M11P1)
*start cutting 100mm circle*
*switch laser off * (M10P1)
*switch laser on and start cutting 200mm circle* (M11P1)
*switch laser off* (M10P1)

I have also read that the movement of the z axis need to play a part here in the switching of the laser. I have many DXF files from my previous projects, so i have the cnc code i need , except i need to edit the files and insert the proper code in the right places.
Thanx
Andre
