Hi Andre,
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.
One route you could try is to load your completed DXF into LazyCam and use the attached post processor (unzip and place Laser.pst into the Mach3 folder then select it within the LazyCam, posting options) this will put the M11P1 / M10P1 commands in the right places.
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.
The PWM speed control is well documented on the forum so a search should provide all the details you need.
(Mainly because I use Art’s ‘Impact / Laser engraving plugin’ quite a lot – the Mach3 PWM output and the plugin don’t play nicely together so I have reverted to splitting my jobs into ‘engraving’ and ‘profiling’ toolpaths and then adjusting the power setting manually, treating it as a ‘tool change’).
Tweakie.
