Interfacing to Ah-ha control
« on: January 22, 2011, 01:35:45 PM »
I have a mill set up with Ah-ha iron. The motherboard in the computer died and mobos with ISA slots are hard to find (read extinct).  So, I would like to keep using the motor driver box but with Mach3 and an interface card that will fit in a PCI (or PCI-e or X) slot.
Any guidance will be appreciated!

Not possible to do that I am afraid, if you can find the pinouts and your drives can accept Step and Direction signals then you could wire up to the parallel port and run from there.

New MOBOs with ISA are still available.

Where and at what price?  I have seen some but they were pretty pricey.
I do have the pinout/signals for the Ah-ha IFB (step, direction, +/- limits and aux I/O).

Should be straightforward enough then, I would get a breakout board as it makes connections easier and will afford some protection to the parallel port if you wire something wrong.

Oh I preume the Step/Dir signals are 5v? I have seen some servo drives that require 12 or 15v Step/Dir signals.

Even if they aren't 5 volt.. that can be solved with a simple opto-isolator. I would recommend using them anyways.

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.

Richard - Thanks, I look forward to what ever docs you might have.  I have the Ah-ha user manual V3.1, but nothing beyond that.  It gives the pinouts of the IFB and the Aux DB25.

Hi,

I have helped a few customers interface our controls to the old Ah-ha drive boxes.  All you need to do is make a crossover cable from their (I think DB37) to a DB25.  I just did it with 2 connectors and soldered wires in between.  Attached is a simple doc that I made a few years ago when I set one up.  There are 2 pins that need to be jumper-ed for enable, and they are not on this doc so you will need to look them up.  Or you could just make a cable and connect the DB37 to a BOB.

PS. I just realized the PDF only shows the connections I made to the PPort.  So it really doesn't help you.  But I do know it can be done, I just don't have a document on it any more.  From what I remember all the IO is 5V and it uses standard Step and Dir.

are1987 - I hate to appear thick, but what is "our controls"?  Do you mean the Mach software or is there a specific breakout board?  I think I understand what you mean, that is, use the PP and rewire to the Ah-ha 37 pin Dsub and use Mach as the driving software.  Am I close?
