Hi:

  I cant speak to cooling, my lasers are air cooled, but when I did use water, I just added some car windshield antifreeze to it.

As to the m3, there is no button set, but it is possible to make a script button to activate an M3. Im just so used to clicking on MDI
where I have an M3 at the top, and I do a single line execute on it, then swap back to code screen, that I never got around to
adding a button to my screen. You only need to find a spot for a button, name it something like MyM3Caller, and then add a script
to your libraries called MyM3Caller(state) and in that script call a Engine.GCode("M3"); Add another to turn it off. I dont advise a
toggle button unless you wish to add some logic to figure out if the m3 is on or off before deciding to turn it off or on..

Hi everyone
After a lot of fails , i manage to get what is wrong on my laser power. Take it away the source problems
i notice , my laser is to powerful on minim power . How i figure out ? I explain.
I made a black square at 100x100mm and i start to engrave . During engrave i try to adjust manual the power ,
and i notice , i can get only 10% grey and after fine adjust jump instead to 100% (black) ;
So i start to find a solution , and better was to calsulate the speed travel , frequency of PWM and duration pulse
on that speed. Finaly i was impress myself , the good result start to arrive .
I put some photos below. I can engrave like that almost like multipass engrave at 1mm deep with very good result when
you don't look face to face to the picture.

Thanks

Thanks Tweakie . To be honest you get a lot of credit for that , you say to me first about Pokeys , Auggie , Art and rest of
nice peoples here . I want to thanks everyone who give me an advice and correct me when i do mistakes.
Thanks to everyone . Anyway now become more seriously , i got more and more attracted by laser.
I want to build my own RF tube right now. I collect some information about those RF lasers and ... why not
what i can lose , some money , nahh knowledge arrive from try and mistakes .
I will start next month , now i'm block in France because of that " stupid and imaginary corrona virus"
i don't believe that anyway .
I will post the news here

Bobby:

  You have showed how much perserverance is important. Not giving up leads to the best results
and youve shown that very well. Nice work!. When I was developing Mach3, I had thousands of
blue screens of death before I finally managed to take over Windows to make a timer work my way.
  It took 6 months to prove to myself that I could do that when pretty much everyone said it
couldnt be done. Sometimes you have to go with faith in your abilities and just persevere. It
doesnt always pay off, but when it does it is very gratifying. Be gratified, your photos look as
professional as any Ive seen.

  Its been very nice watching your progress to the point where you've mastered both
Auggie and your laser. Im impressed.

Thanks for you kind words . I was off a while bussy with my house
I was surpised when i comeback to laser, i change the laser room and after some days i try to engrave a small photo 80x94mm and a error pop out "exasperation code " xxxx
dont ask me the error number because i forgot until next day . Single way to pass that error was to change the size at 81x96mm or other size and work fine . After some hours i try to reproduce that error
but was impossible , no error at all. No ideea what was about .
I will post some pictures , work better and better .
Thanks again to everyone

Yeah, those codes are appropriately named. They drive me nuts at times..

(Nice work)

Thanks ... well like i says , i'm on again playing with my laser and i figure out something strange and very important in my opinion.
When i was in France i buy some good quality playwood from Germany so the photos engrave ok . Some days before i start to engrave one photo , a normal resolution like 1200x1600px and
surprise , the laser even i increase the power more than i was need before for same type of dimension , 140x210mm refuse to made the dark brown color on wood .
Literaly he cut deep almost 1mm and no way to get even brown , i got something like very light brown . I got piss off and i start to made a ,mess tru' my polywood to found that piece of same type of material .
No way to find , but i'm ordonated in my way and usualy i memorise everything i made for any photo i engrave . I set my laser identical , i take one good succeded photo and i engrave same code on the back of that photo .
Same story , the laser cut but dont burn .......  ??? ???
Well ... doing the time back in my memory i remember , when i was in France the polywood has always some high moisture because humidity was very high in my town . Moving back in Romania , humidity is normal here
maybe a little dry if don't rain for a while . And.. i take one ordinary polywood , a brush with water on both sides , a thin layer , i let to dry couple of minute and i start engrave .
In that moment the dark brown almost black coming on the wood.
In conclusion , if polywood dont have hight moisture , the full white-brown scale is impossible .

Out of toppic ... what gcode comand use Auggie to change the power of a laser 0-100 ?
I found a extension for inkscape , i modify the code and now work perfect with auggie but wont change the power level . I need to do manualy anytime .. no clue :-\

Some work below
I forgot to say .. the image was very low resolution , only 540px and 44kb
Thanks
Bobby

Hi:

Good to know about th emoistur elevel..thx


For power, just use a spindle command, like S100 for 100%, and S50 for 50%..

Well .. that i try in first case , but without succes , i try to research . No way to control power during the GCODE. Also i try in single MDi ,
same result , the power will not modify ,only manualy on input box or slider.
Also today i want to add a button on screen for one realy , and no way to made it to work.
I start watching you tutorial here https://youtu.be/AtnLlfho5BU , but no way to see the code for other buttons like i see in you vid.
So .. i anyway i was needed two buttons so i say to made a small screen with two or more buttons and when i try to destroy screen for new one
i receive two different errors everytime when i want to destroy screen .
I even update the auggie on last version i found on website but same result .
I put some screenshoot below .
The system is win7 x64 and i will dont change for 10 or whatever , i work hard to downgrade the bios to bypass the win7  :(
thanks

Edit: ups , upload the wrong screenshot  :-\
