Looks like an extremely neat solution - if you go for it please let us know how it performs.

Please check that you are using a 32 bit version of Win 7 (64 bit versions do not work with the parallel port).

Firstly, check the manufacturers data sheet to make certain that you have the correct wire connections for that stepper motor ( H256-28-4A I can’t seem to find that one to verify your wire colours). Check that your Xylotex Enable jumpers are in place.
If you are using the Parallel Port then check in Device Manager for the address of your LPT port and check that the correct address is entered in Mach3 for Port1 & that it is Enabled. Then check the Xylotex data sheet to make sure you have the correct Step and Direction pins set in Mach3 (Ports & Pins / Motor Outputs) also that the Step and Direction Ports are set to Port 1.

you mean by combining M11/M10 and pwm like you did with optocoupler?

At the moment I don't see a better way.

You are probably right about the S### delay in Mach3 although in Mach4 the S### is, if anything, too fast

I already had a look at it but noticed it was more about grbl setups. Can it be fitted to Mach3 setup?

I think it can (at least it did when I last used it) but you would have to check with them.

For your vector engraving why not just modify the Aspire post-processor to include the M11/M10 commands for the On/Off operation and use your control board's PWM output to control the power level.
Another possibility...
If your control board was set-up so that 100% PWM was full power and 0% was no power or Off then the M11/M10 would be unnecessary and you could control your laser just by the PWM (assuming it is capable of switching fast enough).

There is plenty of room for experimentation so perhaps just try various methods and see what suits you best.

Take a look at PicLaserLite http://www.picengrave.com/ it is, I think, more suited to diode laser operation than the Mach3 plugin.

Many thanks for the link, I really do like that corner tree.

At that size it is a job for a purpose built vinyl cutter (rather than my CNC machine, which is essentially a wood router) but I can call on a friend who has an A2 size vinyl cutter that I can use.

As you say 'very limited' I can only cut the size of the machine bed at any one time. I have done many multicolored, some laminated and some interleaved.

I certainly like your large wall decorations, perhaps you would be good enough to share the .dxf or Gcode files for that work ??

Have you now settled on using Mach3 version R3. 043.062 for both Parallel Port and ESS operation. ??

6 years on and I am still cutting vinyl (sticky backed plastic)  

Che Guevara (when alive, he was loved in South America, hated in North America and to this day there is still divided opinion around the world) he is certainly a topic of discussion but I think this will always remain an iconic imiage. I have included my .dxf file if anyone else wants to cut this image.
