General Mach Discussion / Parallel Port Pin 1 problem
« on: December 17, 2009, 10:38:23 PM »
 ???

I don't know what caused this but pin 1 of the parallel port stopped functioning as my X axis step output.  I tried using pin 1 as the direction output instead to no avail.  Tried using it with the Y and Z axis, but still no success.

Has anyone had this problem before?  I am using all of the output pins, so I can't just change to another pin.  I've tried upgrading to 3.45, without success, and given the port driver causing problems with laptops, I went back to version 2.65.

I know the parallel port output is the problem as I have tested the outputs with a digital probe.  It is not my breakout board.

Thanks in advance for any suggestions.

VB and the development of wizards / How to attach VB script to button
« on: September 13, 2007, 02:55:46 PM »
I'm in Screen4, I've created a new button.  However, after reviewing Wiki, I still do not have a clue as to how to attach a VB macro to the button's press event.

Can someone list code that will toggle "Enable 1" on and off when the button is pressed?

Given that I now have "toggle Enable 1" VB code in a macro, how do I attach it to the button's press event?

I need specific instructions as I can't find the answers in Wiki.  Too confused I guess.

General Mach Discussion / How to use Mach3 outputs?
« on: September 10, 2007, 04:26:44 PM »
I know how to assign outputs to the spindle, flood, etc.  These have specific menu entries in "Config", "Ports and Pins", and tabs, "Output Signals" and "Spindle Setup".  However, lets say I have enabled a MACH3 output to turn on an auxiliary 120VAC, and I have assigned it a pin number.

How would I use G-code to tell MACH3 to turn on the output for "Auxiliary 120VAC"?

How can I turn on the MACH3 output for "Auxiliary 120VAC" while working in the MACH3 software, which would be like the "Spindle Toggle" button in "Diagnostics"?

General Mach Discussion / Charge Pump Signal Hiccup
« on: September 07, 2007, 07:12:45 PM »
I've struggled with this for two days.  I know for a fact that Mach3's 12.5kHz charge pump signal is 12.1kHz, and it has such a bad hiccup every second or so, that a microprocessor counter routine to find the input frequency rejects the signal completely and executes code that's for a "no signal" condition.

I have a relay that stays on except for an off condition for a split second every second or so.  I know for a fact that the relay's off condition is caused by the hiccup in the charge pump signal.  I've confirmed this with a Function Generator emulating the charge pump's 12.1kHz.

Has anyone else encountered this, or do you have a work around?
