Here's a video of how the machine shakes:

Hi Nikolaj,

PicLaser demo version can be downloaded from here http://www.piclaser.com/
Try it to see if it meets your needs.

Tweakie.

Hello everybody. Thanks for the links and help.
Two days of experiments gave nothing.

Tweakie -  i found such a photo.  http://prntscr.com/eypaj9      Where can I get a postprocessor with that name   "Tweake M10-M11.dgp"   for Dotg?

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.

Did you try to download and install it? I think it will allow you to play with it without a licence, but will put watermarks on your image.

There are watermarks.
But when I try to press the launch, a window for entering the key pops up.
I can not try.
I can only buy and use immediately.
Maybe I'm doing something wrong?

Hi Nikolaj,

Did you check PicEngrave at www.picengrave.com ?
It may do what you want. It does have the option of variable feedrate, but not sure about the M10/M11. Haven't used it for a long time, but I am sure Tweakie will soon chime in and give you a better reply.

Dan

Thank you ! I looked at your link. There is no trial version of the program. I'm afraid to pay for what might not work with my laser ...
I do not know what to do.
Tweak did not answer me.

Hi Nikolaj,

The DotG X axis motion is 'stop-start' so, in operation, it will be 'jerky'. This can, top some extent, be reduced by selecting a suitable feed-rate / Acceleration.
The 'virtual B axis' movement is necessary to trigger the M10 / M11 commands whilst the X axis is stationary (the M10 / M11 commands will only take effect at the instant of an axis movement).

Hope this helps.

Tweakie.

Hey. Tweaks.
Now I understand why these commands are used.
Their task is to turn on and off when the X axis is not moving.

But I do not have a solution at the moment.
Dotzh is not suitable for preparing the G code even with postprocess for M11P and M10P commands.

I've tried many other programs to prepare G-code. I even tried the program for burning with the filament of CHPU. But nothing happened.

Is there a program that prepares G - with M11P and M10P - without jerks?
Paid? Free use? Maybe an article about her is somewhere on the forum?

But still I have a little progress, I used the program ArtCAM 2008 to get G code for engraving. The essence of using a small movement of the Z axis - which can be replaced by the virtual B axis and even in pair with the M11n / M10P command. It works, but not as qualitatively as a plugin.
I still have not figured out how to correctly replace the data from the Z-axis with data with the M111 / D1 / M10n1 command.

Can you tell me? Help?

I will attach the successful G code to the message.

Thanks for the nice reception on the forum!
Thanks for the link to Mach3Version3.043.062. I was looking for an older version with respect to .066, but I did not find it. Soon I'll try it in action.

By plugin. I have a fixed speed. But this does not take away the delay.
The plugin program is good.
It's a pity there is no tuning of the power of burning.

But with control via the virtual axis B nothing happened.
More precisely, the virtual axis itself works. But the CNC machine still works jerky.
The article you dumped - I also read and translated.
But I do not really understand how the virtual B axis changes something.
It seems to me that DotG does not correctly calculate the X axis movement.
Maybe you have an example of a working code - which works fine without jerking. I can try it for myself. True, I have a limited desktop size of 200x450 millimeters.

Thank you in advance.) Nikolaj

Hey. Greeting from far away! I'm from Belarus from the city of Minsk.
Sorry for my bad English. I use google translator.
For half a year I have been studying the theme of a solid-state laser. I did a lot of experiments and achieved good results. I have a channel on youtube. There is a video about my progress. I can post a link to the video only with your permission. You're the master here) I read almost all of the 97 pages of this topic - using an interpreter. I even began to understand the humor on the forum) Your projects are everywhere) Everything is pretty well written! Thank you for your work.

Closer to the point)

a)
I managed with your help to run the plugin Engraving DLL v1.2s - works fine. Thank you ! But there was a problem. Laser power adjustment is required, and in this plug-in this is not possible. I need laser engraving on natural skin. And there it is necessary to regulate the depth of the burn. Moreover, the plugin does not behave correctly on my machine. It makes a move to the right, then immediately to the left, and then a pause of about 500 milliseconds. This greatly slows down processing. What G code is used in the plugin - I have not found it anywhere. Therefore, I can not edit it. I realized that the principle is based on changing the pulse frequency of 40 microseconds in length. Do you have a G code from the plugin for example? To understand his work?
I tried changing the processing speed and accuracy to 0.1 millimeter. But this is not enough.

B)
I tried to create my G code with DotG v0631. I tried to manually adjust the laser power. This also did not work ... I still did not understand how to check whether my Mac3 sees the commands M11P1 and M10 P1.

I have version Mach3 R3.043.066 - it is higher than version Mach3 R3.043.056. So these teams should work. But this does not happen - my homemade CNC machine runs in jerks - which was not the case with Plug Engraving. Here is an example of my code:

(- DotG program -)
(X = 0 to 160 Y = 0 to 100)

G17 G21 G40
G80 G90 G94
F1000
M10P1 b0
G0 X0 Y0


G0 X151 Y5.25
M11P1 b1
 
G1 X150.75 F1000

M10P1 b0

G0 X151.25 Y5.5
M11P1 b1

Is it correct? My machine brakes at each of these points.
How can I check whether the M10P1 and M11P1 commands work?
How to create a normal code with M10P1 / M11P1 commands?

at)
Of course I want the best of options. To control the laser power at each point of burning. I read a lot of your articles. And I saw that you use command C *** for power adjustment where S0 is 0% power, and S1000 (or S100) is 100% power.
But as soon as I add the S *** command - the CNC machine starts working slowly at once.
It's strange why this does not happen when working with a palagin.
What does your G code look like? Show me your example.

Conclusion. The plugin works fine, but there is no power adjustment and pauses in 500 microseconds. M10P1 b0 and M11P1 b1 I think they do not work for me. The control of the spindle command (PWM) slows down the machine.

You would have helped me a lot.
Thanks for the help !
