If I buy the controller you suggest and mach4 will this resolve the timing problems.

Unfortunately I do not have a plasma set-up to test so cannot answer your question with any certainty. Perhaps reading and asking questions on the Warp9 forum would be the way forward.

I shall purchase Aspires add on for creating laser work, images cutouts etc and try it.

Hi George,

At this moment in time that is not such a good idea.  When Vectric say that their add-on supports the ESS and Mach4, then that would be the time to buy and not before.  My pp will not magically make it work with Mach4.

Currently Warp9 have their own laser raster set-up for Mach4 which still needs some work but it is getting there slowly. My suggestion is that you try that before doing anything else. Setting it up is a bit tricky but it is not rocket science and Andy at Warp9 is always there to help if required.

Hi George,

I don't know for sure but as far as I am aware it will not be necessary to use a pp with the output from the Aspire Laser add-on.

Most of the new laser raster control software's only generate the Gcode for the raster pattern - the actual laser control / switching is done directly, on-the-fly.

As an example this image was laser, raster scanned, onto some Birch plywood using the 57CNC controller and no Gcode was produced. With this method it is often easier to raster scan things that would otherwise be vector produced such as text, etc.

Hi Bob,

Any of the US or EU manufactured controllers are good.
The Warp9 ESS is a good all-rounder and has plasma capability. Check out their website and forum for more details.

Way back in Post#1027;  https://www.machsupport.com/forum/index.php?topic=12444.msg250840#msg250840
I showed a picture of how I modified a ribbon cable to invert and change the pin allocation of an Active High, 57CNC generated PWM signal for connection to the Active Low input of my laser PSU. At the time no interest was shown but as coincidences go I have just had two requests (from different sources) to explain how the transistor is connected and how it works. On the off chance that others may also be curious, the following diagram shows the connections and explains the mystery of how the transistor gets it’s Vcc.

That's not the pp that's your CV settings. Just to test, turn off CV and run in Exact Stop mode.
Basically, your motor tuning Acceleration need to increase and/or your Velocity needs to be reduced.
