Art,

Thank you for the time you have spent with the plugin, it is much appreciated.

I have been set the challenge of how small a checker board (8 x 8 squares) can be engraved and still resolved under a microscope - at the moment I am down to 0.5mm but hoping to get smaller than this using the plugin.

Tweakie.


btw. I think Bdocks code is the current download http://www.machsupport.com/plugins.php

Tweakie,

I am still trying to figure this out so bear with me.  The solenoid needs something to make it fire.  I am under the impression that Andrea was using a drive to fire the solenoid. IE gecko or....  I have all 4 axes in use so I was wondering if I could use my PLC (it is set up for a toolchanger with outputs to spare) to fire the solenoid.  This of course is if my assumptions on how this works is correct.... ?

all the best, Henry

Henry:
 The plc probably cannot process the 40us pulses ast enough.. though that depends on the plc..some can..

 You simply feed the output to the plc, write a program for it, and see if it can.. I dont think so though..

Art -

Thank you that is what I was looking for, I feared it but thought it would not be fast enough either and defer to your opinion.  I will look into how to add an additional drive.  I am running a Campbell board with all axes full.

Great thread and fantsatic information. Thanks for paving the way Andrea!
All the best, Henry

Hi Tweakie

From the picture one might have thought that we had the same problem.
I saw your new photos, I couldnt have the same quality of your laser...
In any case, now that Art has corrected the DLL, can I be happy.
I must say that Art is the best as always

Have you tried the more newest DLL, also  to you working?

Andrea

Sorry for my bad English, I hope I never say the wrong things.

Hi Art

Thanks ART.

The newest DLL work perfectly.
Thank you for the time you've taken away from your work and you gave me.

I am indebted to you, as I told you many years ago, if you come to Italy to Venice you are my guest ...

You are the best :-) ;-)

Thanks,
Andrea

Excellent work Obal.

I am having a problem with "banding" (horizontal bands of differing contrast) please look at this image http://www.cooperman.talktalk.net/files/27_files/image762.jpg

On one of your images it looks like you have the same problem - Is this the case ?

Tweaky:

  Its mathmatical in nature. If a greyscvale varyies subtlely , it can create such bands due to the math of the grey scale interpreter, the imapcts try to fill in a grey scale of the line, so if the next line is only differing in very small ways, the math involeved could simply shift a bit one way, if each line is the same variation, then bands can occur.. not much you can do about it..
