You need to set your stepper motor control to 1/8 step (link or DIP switch).
Enter figures in calculator then this gives your steps per unit (arrow shows where 8 micro-steps goes).

Thanks for the kind words Sam.

Unfortunately there are only about 5 or 6 of us (that I am aware of) that currently use this plugin with a laser as those before me, who could not get it to work, have now taken other routes.
Our minority Mach group desperately needs new members.

Even Art has purchased a laser machine that uses the HPGL printer link rather than GCode and Mach so I doubt he will ever get to use his own plugin

1/8 micro-step would be best.

Hi Richard,

Thanks for posting the file, most interesting.
I did laugh a couple of times but their diagrammatic representations (assuming them to be correct) are extremely good and leave little doubt as to how stuff is connected. I wonder how well the board actually works though.

Mikee,

USB is designed to be plugged and unplugged with the PC powered up.
Just switch off any power unit you have for the motors and unplug the USB (I doubt you will ever wear out the contacts but if you did they are probably easy enough to replace).

Hi William,

Enter the data then press the 'Return' key. 

(This rule applies across the board with Mach and it just becomes routine so we perhaps take it for granted that everyone knows about it and it doesn't get included as an instruction).
