I did some more testing on my machine and found my belt had some miss alignment corrected it and also brought my axis velocity and acceleration down
Got a much better result to my engraving also decide only to stay way from engraving with the zigzag pattern and stick to the fill method

Would like to thank you for all you assist Tweakie.CNC
I am using Aspire for our engraving and would like to know if you have any other suggestions on tool set up or perhaps a mod to my post processor

Some more pics
Three of the sides are correct and only one is not correct
Big square was made with zigzag using y axis the small square was made using the x axis

I have attached the files as per request
The quick engrave 1 file i use the y axis to do the zigzag and the test square 0 deg i use the x axis to do the engraving
I have the same issue with both files
some times i will have this issue with only one side of the square 
Also did another test with engraving a letter (B)
same velocity and acceleration settings but with different kurnel settings
the machine is using a parallel port
i did determent with DriverTest.exe witch is the best kurnel speed for the machine and it is 35khz
but i did also engrave with the machine using the impact/engrave plug in for mach3 and the pictures turned out with out any problem and i used a kurnel speed of 25khz

Please let me know if you require more information and thank you for the assistance so far

I have try adjusting Velocity and Acceleration still same results
I have used the same drawing only change i have made it the way it does the engraving
Engraves by going around the design and not zigzag using exactly the same settings

So my question is where can the problem be
Because if i am loosing steps why is the one type engraving correct and the other one not correct

Good day

I have a problem when i engrave on my laser machine
When i engrave with a zigzag patron the design moves in one direction even tho the mach 3 software say it is in position
but if i engrave in a fill it engraves without moving the design
also if i do normal cutting of parts all comes out fine and straight
 
I made a couple of test and the results is always the same in the same direction and the same amount   
Attach some photo of the out come of my test
has any body came across a simile problem and do you have advice
machine as been doing it from the begging

I use aspire to do the designs and to write the gcodes

Thank you in advance

Good day
I have download the impact and engrave add on for mach 3 
I have some questions on how to wire and set up
1.Witch pins do i wire up the laser to
    Do i need to wire the pwm signal to the break out board
    And the enable signal
I require details on how to set up the config in pins and port on mach 3
Because  there is now clear manual on the set up or the wiring of this
Can any body please provide any details on this on how thy set up there laser
I am using a co2 laser
See attach photo of break out board
The manual provide in post #7 has no clear description on wiring or pin config and example will be nice
Thank you in advance
