Assuming you are using the parallel port...

Possibly one of many reasons but it could be that your parallel port output is at 3.3Volt TTL and your driver is expecting 5Volt TTL. Check your PC to see if it has a 5Volt PCI slot and if so fit a 5Volt PCI parallel port card. This thread refers: http://www.machsupport.com/forum/index.php/topic,34848.0.html

General Mach Discussion / Re: Axis direction doesn't always change

Hi Martin,

I think Gerry has mentioned the most likely cause of the problem - 3.3V TTL signals where 5V TTL is expected.

Hi Martin,

You need to leave the voltmeter connected to the axis direction pin. Make a note of the voltage for each direction of the axis movement when jogging. When it goes in the wrong direction is the voltage correct for that axis direction ?

Mach4 General Discussion / Re: Mach 4 and parallel port

« on: November 09, 2017, 02:48:28 AM »

Hi Sage,

If it’s any help…

I did use the parallel port plugin with Mach4 for some while but I never could get the charge pump to work and also had some problems with the PWM range of values.
I switched to using the ESS with Mach4 (the USS plugin may be some while catching up) although I only use Mach4 for testing / experimentation – all serious production work is still done with Mach3.
I recently purchased the Pokeys 57CNC (to use with Auggie) but have yet to try it with Mach4.

what would be the best learning source for mach3 and CNC in general?

Hi Alex,

Nothing really beats hands-on practical experience.
A good CAD/CAM software (such as Vectric) then see what you can and can't do. Each time you run into a problem check the Mach3 manual, search the forum, ask the question. I have been using Mach2/3 for more than 10 years now and I am still learning.

Hi Alex,

I think that as long as the driver test does not show wild variations in the pulse timing then all is well and nothing needs changing.
