[CAD_CAM_EDM_DRO] One shot circuits

Mariss
I downloaded the one shot circuits that you designed for Mach1.
I noticed on one that uses the 4538 chip that pin 1 is not shown connected
to ground.
It may confuse someone while building it.
I have used this same circuit on my interface PCB, the values are a little
diffrent but not much.
Thanks for a great Stepper motor driver. I use them in my router.
