General Mach Discussion / Re: Mach3 setup parallel port question- help
« on: September 13, 2009, 12:25:55 PM »
I used a completely different machine. I have a computer that is totally dedicated to this project now and it has only windows XP and mach3 software on it. I did the exact load of mach3 and it worked perfectly without having to load special drivers or any advanced tweaks to the setup.

Yes!! Did a standard install on a completely different machine. I checked the pins with an oscilloscope and was able to see data on my x,y,z axis pins. My jog is moving the motors...Thanks for all your input. I'm guessing the printer port was bad and leave it at that.

I'm on a dumb terminal at my job. It's amazing I have internet access at all. I'm sure thats the reason for the broken link. I'll check it the smoothstepper when I get home. Thanks...

JB, I am sold on USB. I went to your website and found the smoothstepper USB board, interesting!! Anyway, tried to download the docs- broken link???.
     Thanks for your info and I'll try a few more things including a plugin parallel card, getting one today. I'm sure we all will have a USB interface soon.

The cable was removed and I was hooking an oscilloscope directly to the pins at the PC. I see a high on pin 10, still jogging shows no movement but 0 volts on any of the data pins. I'm thinking about going to a surplus computer shop and trying to get a parallel  port card if possible. I'm also running windows XP 900mhz with 256meg of ram...I'm getting a better machine in the mail. Nevertheless, I'm thinking I could still get it running with what I have.

Thanks for the reply, I have verified the port ( 0x378) and have assigned data pins 2,3 xaxis, 4,5 y axis and z is pins 6 and 7 for Dir and Step. My voltage on any pins 2-7 sits at 0 volts no matter what axis I jog back and forth. I have never seen anything but 0 volts on these pins 2-7
      The only thing I have done externally is reset the Estop through pin 10 so I am able to jog. I did this with a resistor to ground on pin 10. In other words, I am able to reset the software with my external e-stop so something is working with the parallel port. I'm still pointing to a bad parallel port unless I have overlooked something- again, I'm a newbie......

I just loaded mach3mill and configured my setup to my parallel port. I have a 3-axis xylotex system I'm trying to jog the motors.( Nothing, no movement at all ) After a few hours I have come to the conclusion that my parallel port is bad. I'm definately a newbie but am able to reset the estop and simulate the jog. I am monitoring the step and drive pins on each axis with a digital oscilloscope and see no activity whatsoever when I jog any axis. I have pin 10 as my e-stop and am able to reset that externally through the parallel port so I know that it's aknowledging that, so I feel my LPT1 address is correct. My question is: Should I see activity on the parallel port when I jog or is there a handshake that needs to take place before any of that happens. I have another computer arriving within the week to try my luck again. Anybody else experience these problems. Thanks for any input...
