 :) Good night ART SOFT . Sorry for the delay.
I think you're right.
The logarithm using with  plugin  mach3 (Engraving Trigger for Laser)  , it's just on and off.
The power supply of direct current CCW,Not able to turn very fast laser tube.

THIS IS THE BIGGEST PROBLEM.

Materials;
CO2 LASER 40w. Chinesse.
SUPLLY POWER 100W. Chinesse.

Many of my tests can watch them on GRANITE BLACK ZIMBAUE,
You can see that there is No grayscale, the only solution is to apply with Adobe Photoshop, the tool
half tone bitmap.

HALFTONE SCREEN,
IMPUT 100 dpi, Output 100,
FREQUENCY :  85
Angle : 45
SHAPE : ELLIPSE .
Good night ART SOFT . Sorry for the delay.

The photos have a low resolution 100 dpi, speed 4500 mm p / minute, about two hores for  a picture of 260mm 260mm.


My question is:
How do you think would be walking mach3 plugin, with a laser pulsed   ??
You think with a laser SYNRAD 25 w radio frequency would be allright ?.

IS IMPOSSIBLE HAVE A LASER WITH GRAYSCALE???.

PLEASE I NEED HELP , WITH C++.
Good morning, I live in Spain My Names is Josep.
Thanks for everything, I built a small laser machine for engraver, Co2 40 w.
 I tested the changes engraver.dll file you left on the forum.
Thanks everything works fine.
took many tests with the plugin, the problem is that I can not different  While grayscale photos.
It would be possible to modify the source code to select different types of output power as a function of the grayscale photo.

The problem is as follows: laser power we modify the PWM input signal on the power supply 0, 5 volts in a train of pulses.

  0 volts, it would be black.
  2.5 volts, 50% black 50% white
  5 volts, it would be white.

It would be possible to change this scale ?? .
