Mach4 General Discussion / Re: Using a PWM controlled laser, Mach 4 vs Mach3

The Optocoupler I used was Type PC123 and the 1k resistor was 1/8th Watt.
I made the 25 way connector circuit board but I have seen DB25 Male to Female Test / Measurement Adapters available on ebay – perhaps worth a look.
Be careful of the cheap Chinese 4 axis boards – sometimes they work and sometimes they don’t. This forum has plenty tales of woe from buyers of the cheap stuff.
If you are going to be using the Parallel Port then a 5 Volt version is essential.
You cannot use the Parallel Port and the ESS at the same time.
If you have an ESS then why not use the Warp9 laser control system ?
