Stitos,

I am not at the same location as the machine but I think this profile is correct.

And I tried it and it goes well, I see strange is that when I very low speed (30cm/min) will not turn on the laser. "Should be activated at any speed?

If the laser was activated at any speed then it would burn when stationary which is not what is required. (The stationary thing is a law of physics which applies to the X Axis changing it's direction)

good morning,
 I'm making a machine to work at high speed.
 While this plugin will respond at speeds of 50 m / min or 100m/min?
 Pulse rate varied by varying the speed of work?

 best regards

Hi Stitos,

I am sorry buddy but I just do not know all the answers, wish I did  :'(

I run my X Axis at 3500mm/min and I am getting quite good results at this speed. If you will get any improvement at 5000mm/min I really don't know but I would be very interested to hear of your results and perhaps see some pictures of your work.
The pulse rate may be fixed to the image D.P.I. in which case it will vary with speed.

I think I have finally got to the bottom of the 'banding' issue I have been having but it is too early to be sure, lots more testing first  ;)

Hello, I am working right now 20000mm/min with good results, but I want to modify the machine for more speed, removing weight to the head, I'm talking laser.
Pulse then has nothing to do with speed? pulse is associated to the image
More speed to shoot faster pulse?

As able to analyze the signal correctly?
A completely white tendira pulse rate?

Best regards

An image, done this morning, shows horizontal banding (perhaps difficult to see in the photo, but it's there) the banding is related to the image DPI and the image size. An increase in axis speed would make no difference to the dot positions although they would, of course, be placed at a faster rate (within the limitations of the laser operating system). The pulse repetition rate (PRF) must therefore increase with speed. As axis speed is increased there will come a point when the pulse width (PWM) is wider than the gap between successive pulses and no image can be produced. Perhaps not attainable with a moving axis but easily done with a scanner head. There must be an optimum axis speed but I think you are nearer to finding it than I.

Hi,
I have problems, but everything worked affiacate records two images, how to fix?

Two things.....

Make sure you are using the latest version. http://www.machsupport.com/forum/index.php/topic,16446.msg111507.html#msg111507 Copy the DLL from here into your Mach3 / PlugIns folder.

Make sure the axis Scale DRO's are at +1.0000

Hi,
    I did what you said but the problem remains.
