General Mach Discussion / MPG implementation -- HOME Brew

« on: August 03, 2011, 02:16:19 PM »

Hi Fellows
I just made myself an MPG utilizing parts from 2 medical machines and standard electronic components.
Photo attached. (AAA battery shown is only for scale ref)
it doesn't have any switches (not yet as encoder function is all I need) just the MPG.

However, I am not finding a lot of info on how to set it up in Mach3.  I found a bit of info that it must be set up in a LPT2 port.

Could it not be set up on the 4th Axis on LPT1??   since LPT is Bi-directional Could mach3 be set up to become  INPUT only on the 4th Channel?

I do have an LPT2 plug in (need find it) in case I must go with it if LPT1 4th Ch. is not possible.

and last: How to use it.  Where are the controls, (Axis selection, etc.)
Does anybody have any info or Ideas.

General Mach Discussion / Setting up Encoders

« on: February 27, 2009, 05:22:44 PM »

Hi Everyone
I'm trying to set up a machine with Encoders.

I looked for instructional Videos but there nothing specific.

I'm half ways there but stuck:

I Can see the encoder signals in Diagnostics.

I only have ONE LPT port  but I wanted to try and install at least one Encoder

First I tried to just set up under Encoders/MPGs  
Encoder1
Enabled, Channel A to pin13    port 1
Enabled  Channel B to pin 15   p1

Didn't get anywhere with that.


so I also went to INPUTS then in

INPUT#1   Enable,  p1  Ch A to Pin 13
INPUT#2   Enable,  p1  Ch B to Pin 15

So Now I can see the the encoder activity as I turn the shaft in LED lights in Diagnostics.

But I can NOT see How to send those signals to be utilized, COUNTED by mach3 or To Which axis to attach that to

I don't know if I'm supposed to "Share"  to get it to work or if Just created a conflict and nothing will happen even if the LED  Hi/LO states are detected.

I someone can help me with this I can make a Video and Post it here for the instructional Video Archive

Thanks Fellas.

General Mach Discussion / Unable to JOG BACK on Mach3 after limit-switch-tripping

« on: May 05, 2008, 08:56:51 PM »

This is a Question for a moderator (programmers of MACH)
I found this question on the Spanish forum.  I thought it was a good technical question and maybe one that deserves the programmers looking into for modification:

Translated from Spanish:
------------------------

With mach2 if I had a runoff and activated the Reset, (limit switch) then what I would do is to deactivate, with the mouse, the button of reset and with the cursors, jogged back to operating space.

Now with mach3 I cannot do that, if I trip the limit switch, it does not let me deactivate it with the mouse, reason why must turn off the milling machine and turn by hand the small spindle.
Does anyone know How the RESET status can be deactivated?? (to anable jogging back)

a greeting and thousand thanks --cchhaa
