Hello everybody. Thanks for the links and help.
Two days of experiments gave nothing.
Picengrave PRO5 works so dramatically that my machine almost fell apart.
With the configuration and instructions, I figured out - after loading in MACH 3 the machine trembles tremendously.
Dotg - it turns out to be not so bad. He works abruptly, but engraves.
Maybe I have with the settings of parameters Mach 3 that something is wrong?
How to properly adjust the laser for the laser?
Its settings attached.https://drive.google.com/drive/folders/0B2Yl5soaDkgmU0kzRUY2SXF2aVU?usp=sharing
