As far as I am aware it is the length of the impulse on the digital trigger with 40uS for laser and 10uS for magnet.
I have only ever used the 40mS setting.

Anybody else have any more info on this ?

Turning this parameter on the laser pulse is at most 40us. and clear it is 10us. assuming it is a white image?

 I do not quite operation.

Hi Stitos,

Interesting one this.
I just ran two examples at the same power settings etc. The top one with 40uS unchecked and the lower one with 40uS checked and I was going to say that there is no difference between the two - until I saw the photo which does reveal a slight difference (the top one being better, perhaps).
I will investigate this further and see if I get a difference with other work.

(please excuse typo in earlier post 40mS should read 40uS)

This was perhaps a trick of the light or camera function but from more tests carried out I can safely say that ( for my setup and triggering circuit ) it makes no difference at all if 40uS is checked or not, the end results are the same.

I really feel the same, this function does nothing when finishing a job. So to ask if anyone knew it.

 The trigger rate is variable,
 varies according to the image and the speed of work?
 There is a limit to maximum frequency?

 A laser-white image fills it completely, it will not points.
 Because the electromagnet a white image if he does spot?

For others that follow....

The trigger pulse width (digital trigger) will vary dependant on kernel speed.

It is 40uS at a kernel speed of 25kHz
      30uS @ 35kHz
      20uS @ 45kHz
      10uS @ 100kHz

But this goes totally to pot if you select Sherline 1/2 pulse mode  ;D

cnl,

Basically it means that the core of the program (a routine called sequence one) is still running.

(use RESET to exit the program prematurely).

To avoid double posting I have added some more information relating to this plugin in this thread, starting here. http://www.machsupport.com/forum/index.php/topic,12444.msg127947.html#msg127947

Robotmar has paved the way for using this Mach3 Impact/Laser Engraver plugin for impact printing. His results are excellent but has anyone else managed to duplicate his success ??

I get good results using a laser but try as I may I just cannot get this magnet impact printing to work successfully. In fact the results are so bad that I am even ashamed to post any pictures of my work. My problem appears to be the usual one of speed where the digital trigger pulses are way too short and the response of the magnet is way too slow.
My next move is to build a magnet with far less mass to the moving parts (much smaller tungsten tip and shorter iron core) to see how well this performs but has anyone any other ideas or suggestions ??
