General Mach Discussion / Re: Interfacing to Ah-ha control

« on: January 22, 2011, 10:56:59 PM »

I have a router at work that uses Ah-Ha controls, I have always wanted to convert it to Mach control.
I believe the isa card is a dio card and I think they made pci versions as well.
I have some docs on the Ah-Ha system at work and will share them with you, I will also look
for a spare ISA mobo. I have a lot of machines that need these so I have eveyrone at work
bring me their old computers.
Monday is a "layoff day" for me so I will post here tuesday on what I have.

Antec has rectifier modules on ebay -  $25 For 50v 30A ,or 80V 25A. Probably the best way for you to go.
Visit his store and you will also find fuse modules

BR549 is probably right, my sensors are wired into the amp. I do not know how fast Mach3 would trip on
one of them. These sensors do not go out often, and I would not have suggested it except that I seen
your sensors are the same as the ones as I put on my last machine. The test I suggested will rule them out
at least. I still have have the bad one, I think I will wire it into mach just to see what will happen.

The Blue proximity sensor, check between the blue and black wires with a multimeter set on dc volts
what is your power supply voltage on the sensors?

Check your sensor, I just retrofitted a machine with these and had a bad one.
If they are NPN NO type, you should have 12v open (24V supply) and <1volt closed.
The voltage should not wander,(my bad one wandered between 2v - 4v open)
please not that the light on mine worked right, but I had random events.
You can get these on Ebay for about $8, direct from China.

I only suggested checking the grounds because when i connected my board (C11G) I did not
realize my amps had both a signal ground and power ground that were not connected internally.
I got lights but no action. If you do not have +5v on pin 5 of your RJ45 then you will not enable
your amps and I believe you are right about a blown chip.
I hope you have better luck with your next board.

Does your ground pass thru from your parallel port to your RJ45 connector? Do you have +5v at the RJ45?
Is the power supplied to the BOB at the connector next to the EN pin?
