Hello everyone ;D

I managed to stabilize the Mr. Tweakie PWM controller with Mach3 ;)
 "http://www.youtube.com/watch?v=N8I5QgCz-lo"
With the same G-code, I managed to burn the image to the center (2.5 mA) and cut out the leaves of the tree and the framework (19 mA) I am happy. :D

If you want you can see the beginning of my work here"http://www.laserfreak.net/forum/viewtopic.php?f=107&t=52456&hilit=cnc+laser+bleu"
But I still have much work to have the same quality as you

Thank you all for your work ;)

Hi Tweakie, :D

 Thanks 1000 times answered me so fast
Your answer reassures me because I try for several days without results
At the same time it is sad because I can not find my PWM laser.
But I still very happy with your system because I can control my 40W CO2 laser in manual low.  With a potentiometer I could not do it in low voltages. Your control installation works perfectly.  ;)
Thank you very much for your work ;D

For now I use Mach3 PWM montages that works more or less
"http://Http://www.sonelec-musique.com/electronique_realisations_conv_pwm_tension_001.html"
I changed the diagram 001ab R4 and R5 by 470ohm this may help some people can be.
But if someone has a solution for the PWM with Mach3 and a laser I would be happy.
In any case a very big thank you.
Continue to make me dream :D

Hello, and thank you for this forum, which gives me a lot. :)
I'm French and I use a translator, thank you to excuse my bad qualities words. :(

A big thank you to Tweakie for your site "http://www.cooperman.talktalk.net" and for your participation in numerous forums. I learned a lot. ;)

I realized your PWM controller and I use the program V16.2
Manually everything works perfectly. ;D
But with Mach3, I get a varying voltage S0 to S1000 but I can not seem to have a constant voltage and frequency is not fixed on 5khtz. Which side can come the problem? Is that I made a mistake or Mach3 is that I can not solve
Thank you for helping me because I'm not experienced with Mach3 :-[
