General Mach Discussion / Re: Installing Mach3 on a Dynamite 2800 machine

Relax; you have a good machine. The spindle takes a BT-30 tool holder with a quick-change lever. It has ball lead screws with good size stepper motors and lots of iron. The machine weighs about 800 pounds so I hope you have something to unload it with and a solid steel table to put it on.

You can change out to gecko drives if you like, but I am using the original driver boards and they work just fine. The only thing you will need is a breakout board, an old PC and lots of patience. When you get your machine home let me know and I will try to help.

I did as you suggested by putting my MPG on to pins 12 and 13 of this second break out board and now it works. Great!!!!! So much for the instruction sheet for this board and I’m not sure what I can do with these other pins.

There is one thing; when I use the MPG the “Y” axis is backwards from what I think it should be. I guess I’ll just have to get use to it or mark something on it so I don’t forget. Being an old Bridgeport man I crank before I think!

Well, anyway thank you for your patience and a job well done. I must say you didn’t give up, “you where like a dog on a bone” you kept up until the job was done. Again I “Thank you!”

Did you just buy that one sold on ebay? Do you have the machine in front of you to look at. I am in Florida, where are you?

Yes, I have manuals, I have all the old stuff. Although I assume you will want to upgrade to Mach3 (as I did) and the old controls will be replaced.

Sorry, I just saw your last two posts.

Yes this new board has a jumper which I have set for pins 2-9 to be inputs. In fact this board has a diagram showing the hook-up for a MPG in this manner. Should be simple, well maybe, but not in my case. Unfortunately I wasted most of the weekend with this problem and now I need to do such things as mow the lawn, but later today I will try your test. Although from previous testing everything indicates the second printer board and cable are now working fine. With nothing coming through the breakout board.

I have two break out boards in my machine and all my tests show I'm not getting the signal through this second board. Both of my break out boards are from CNC in Florida, the first being an older style and this second one is a newer design. My "MPG" works fine running on the old board on port 1 so after much testing I sent back the new board and he replaced without any problems but now I have the same results, nothing! I don't get the signal through the new board, because the pulses are so fast I wonder if this new board could be filtering them out?

That last note about the pins only means the file I sent did not have the correct pin numbers ( I had been changing it around so much). I still have the same problem.

If I put my meter on the 2 or 3 pin from the break out board and go to ground as I turn the MPG I should see 5 volts or some action. Is that correct?

I forgot: the pins are not correct on this XML file. They are really port 2 pin 2 and port 2 pin 3. Sorry for the confusion.

I sent you the XML file as an attachment, but I don't see it here yet. I had checked the cable with my meter by going from pin to pin. But I will chck it as you do. Thank you.

That was a good lead and may still be related to my problem, but I changed it to read: Oxd400 and a few other versions with no change. One other thing is on my second port I have two lines, the first one is I/O Range D400-D407 and the second is I/O D800-D807. The box with "Use Automatic is light and not active, but the "No conflicts is clear. Oh, yes, I also tried the d800 and I enter them a "D" but it changes them to "d".
