General Mach Discussion / New Computer w/ no parallel port

I did a search for information on a fix for this but I'm still confused. Is there a board I can buy now?
Will this Single Port Parallel Port PCI Card work? http://www.ramelectronics.net/html/computer_parallel-port.html#1np

I purchased bearings, ball bushings and blocks, thompson rod (metric) from these guys. They also have linear rail assemblies and accessories and they were prompt with shipping...

The Parallel port booster Camtromics sent me fixed all of my problems! Just got done cutting a circular pocket with islands that needed to be concentric and to size and they were perfect! What out for new computers.They are dropping the output voltages
down to 3.5 volts. Thanks Brian for helping. ;D

Hi Chris,
The company that supplied my control unit(three 452 in/oz motors, three gecko drivers, power supply,cables, etc.(Camtronics) is sending me a parallel port booster.  Maybe I'll get it before the weekend. As soon as I get it I will install and let you know if it fixes it.

Hi Brian,
I think you are onto the problem...

I was able to troubleshoot over the phone with Dan Mauch (nice guy!) and we think we may have it solved. After going thru some tuning stuff in Mach2, he had me check voltages coming out of the PC (Brand new 2.2 ghz Emachine from Best Buy) thru the DB 25 cable. Hooking up meter to pin 3 (controls x axis) and pin 18(common). Going in the direction that it did not miss steps the meter read 3.2 volts.(Still too low) In the direction when it missed steps the meter read .1 volts! Dan is sending me device to amplify the DB 25 output next week. I will let you know if this solves my problem.

Thanks for listening...Danny

The Camtronics box has a +5volts plug in in the back and they supplied a USB cable that adapted from USB to the plug.
I measured from USB cable to PC Case(ground) and got 5 volts. I will take the Camtronics case apart and try to identify its
components.   Danny ???

Changing Prechange number(Mach 3 calls it Dir Pulse) does not make a difference. I emailed Camtronics to find out about the breakout board and have not heard from them yet?
Here is something I have noted. It does not matter if you reverse the motor in the Home/Limits box, the motors always miss steps when they go the same rotational direction (i.e. Clockwise)?

Respond if you want to and I will let you know what Camtronics says. If I don't hear from them I'll open the box and see if I can Identify the breakout board if that will help.

Thanks 
 Danny
