Yes there are vias intacted.
Yes I'm aware there are 2 separate power supply VCC and VDD, gnd 1 and gnd 2.

What should the value of VDD be? 7v?

Hi Craig,
            I will check the VCC and VDD later with multimeter, might get a Oscilloscope soon since I'm doing a lot of electronic project recently.
I use Diptrace 2.4.02PCB software, double sided works quite well in diptrace but not single layer, I tried before and was rejected by the pcb manufacturer 5 times due to short circuit. Single layer still works depend on complexity.

The pin 7 of 6N137 meant to be NC, is this correct?


checked Vcc Vdd Gnd1 Gnd2 in Diptrace schematics, looks alright..:

Let's forget the relay for the moment. I'm not sure if the following schematic works?

The PC817 is replaced with 4N35, because I got some spare 4N35.
I have made the board with components soldered, but didn't work...

A quick question:
Is this schematic correct?

mm....scratch did not work....

Ok I've just built a simple circuit in scratch, the only diode I have is a 1N4007N, is is ok?

Ignore the above I was describing a bob using SN 74act245N, totally different to 74Hc14, sorry..

Thank you for replying.
Tweakie,
This is more like a electronic project I wish to make it myself. Will look into protection diode, thanks.

I did a test on a bob's pin 17 and gnd using a voltmeter for continuity, after entering Mach3 I measure Pin 17 and gnd no continuity, then I type M08 at MDI voltmeter beeping I get 5v, M09 to disconnect or off.
My output setings are:
Output #1   Enabled  Port 1   Pin17   Activ low = off

General Mach Discussion / add relays to Break out board schematics
« on: May 31, 2017, 02:45:46 AM »
Hello all,
            I have created a break out board schematics it is finished and I would like to add a relay for coolant/flood to pin 17, so when coolant is activated the relay clicks, is the illustration below correct?

found it, 74HC2450.
