On the Mach3 main screen is the Jog ON/OFF button illuminated (green around border) ?

Hi,

You could try turning off Constant Velocity and see if that makes any difference.

Alternately there was a Russian software that possibly made a better job than G-Ray, you could try that; https://sites.google.com/site/nikromsoft/home/programmy/drovopal (you may need to use Google or Microsoft Translate).

Have you accidentally clicked on the   Jog ON/OFF Ctrl-Alt-J   button ?

Which version of Mach3 are you using ?

When the MDI box goes blank do you get any message in the Status window ?

Click on History and see if that gives any clues as to what is going wrong.

Hi Art,

I still get many emails and questions about the original plugin and 8 bit image reproduction (from folks all over the world).
Although the plugin is easy enough to use it is not always that easy to achieve good results. The overall set-up is perhaps a bit too complex.
On the other hand, with Auggie (and of course the 57CNC) it is very easy to get good 8 bit image results first time.
I agree, the M3 enable then ON with feed-rate moves and OFF with rapid moves combined with a system to allow changes in the PWM duty cycle without breaking the CV chain is definitely the way forward. I think this method of control is by far the simplest and as you have said, would equally apply to many different systems, not just laser.

You must be gifted - the cheap endmills hardly ever break, it is usually always the expensive ones that go.  ;D

Thanks Art for the kind words. I thought my post would make you smile.  ;)

Back in the day, I started out with Mach2 then moved on to Mach3 – although I have Mach4 set-up and ready to go (using the Warp9 ESS) I am now having my doubts that I will ever use it for any serious work. Currently, Mach3 still rules. Somehow, I need to get more free time so I can get stuck into learning the protocol and application of Auggie scripting then who knows the direction of the future.

Hi Letomoto,

I am pleased that you found the problem.
If it’s any consolation, you did not make a dumb error. Switches are always pulled down for ON here in the UK so you just made an easy mistake.  :)

With Art’s permission…

For many years now I have successfully used Art’s Mach3 Impact / Laser engraving plugin for CO2 laser engraving 8 bit photographic images onto wood (and other materials). Unfortunately, due to the nature of the pulse timing this plugin will only operate via the PC’s Parallel Port, which is rapidly becoming obsolete, so an alternative was desperately needed.

Art never seems to tire of software development and along with a small handful of others I have recently been trying out ‘Auggie’. This FREE software started as an extension of Gearotic Motion but now stands in it’s own right. It is a very basic (trimmed down) CNC solution which incorporates the beautiful ‘S-Curve’ acceleration / deceleration of the Tempest planner (which really should have been incorporated into Mach3 but never was) and it has been designed around the 57CNC USB and Ethernet CNC controller.

Although Auggie would be equally at home with basic CNC milling, routing, etc. it has some advanced features designed specifically for laser use and it can support RF, DC, Diode and most other types of lasers. It does not stop there as Auggie has many more interesting features which, for the most part, are described here;  http://gear2motion.com/auggie

For me, the most important thing about Auggie is that it has the ability to process 8 bit photographic images and although it is a very different process to the old plugin the final results appear very similar. I am still working on how to get the best results with an electromagnet but Auggie can also be used for Impact Electromagnet operation.

In the following pics, one was produced with my CO2 laser and the other with my impact electromagnet.
