VB and the development of wizards / Re: help withusing vbscript to "feedhold" gcode execution

« on: October 19, 2016, 01:12:05 PM »

yes, and excuse my ignorance as i ma not a mach3 expert,  but it is not immediately clear to me why a pause in a sequence of moves would not be considered movement. probably i don't understand the logic behind what feed hold is really used for in practice since im not much of a machinist, but if i had a piece of gcode that had a g4 in a complicated sequence i wanted to pause, i might expect that feedhold will pause the gcode execution. or at least pause at the subsequent movement after the g4. obviously it does not as found empirically.

I agree with you and what you say but Mach3 operates the way it does and that is the way we must learn to use it.

General Mach Discussion / Re: Mach3 and ESS issues on new laptop

« on: October 19, 2016, 01:07:17 PM »

all I have open on the laptop is mach3, cambam, autocad 2006 and a single internet explorer page. I used to run much more on my old laptop

The recommendation is that you can run all these applications on your laptop but not whilst Mach3 is running.

Hi Karl,

I am pleased to hear that you have purchase a genuine Mach3 license.
Follow your motion controller’s set-up procedure.
Copy your license file Mach1Lic.dat into the Mach3 folder.
Do not duplicate the pin numbers allocated to the 0 – 7 Outputs in your Outputs set-up.
For your Outputs 0 – 7 to drive anything (relay etc.) they need a power source as shown in the attached diagram.

Hope this helps.

Please I want to use a 3axis mach3 CNC motion controller USB card breakout board.
1, What are the software I will be needing to install this card on my laptop.
2, how do I reconfigure my mach3 or are there other mach3 designed for motion controller USB card.

First job is to choose which motion controller you will be using but please remember that like most things - you get what you pay for. It is always best to use one which has customer support and repair backup (just for example; PMDX  http://www.pmdx.com/  or Warp9 http://warp9td.com/ but there are others so please check).
The motion controller will come with instructions (possibly recommending to use a particular version of Mach3) and an installation program which should make the setting-up an easy and painless process.

If you attach your .xml file I will take a look.

The file is in your Mach3 folder named <your profile>.xml (typically Mach3Mill.xml) copy it then rename it to KarlJuettner.xml then use the reply / Additional Options tabs to attach it to your reply.

General Mach Discussion / Re: BB card vs motion control card

« on: October 16, 2016, 08:26:59 AM »

If i'm wrong someone will correct me but I'm fairly certain the the parallel port will not handle the encoder signal and pulse rates needed for servos very well. My encoders are 10,000 per rev and motors can do 3000 rpm so it needs a pretty fast connection.

This may be entering into the twilight zone but note to self…
“Tweakie be prepared to be hammered” 

Mach3 is not a closed loop system so does not get to see the higher speed encoder signals that are required by the servo drives to verify that the step direction signals have been performed correctly.

In the end one  can add a parallel card(s) to any computer .

There are many good reasons for using an external motion controller although my personal preference is using the parallel port with Windows XP but
please keep in mind that the parallel port can only be used with 32 bit operating systems running Windows 7 (or earlier) and laptops are not supported.

General Mach Discussion / Re: Mach3 incorrectly interpreting gcode

« on: October 14, 2016, 10:33:35 AM »

I think you need to go into Config. / General Config. and change the IJ Mode.

If you then Regen. Toolpath the display will be correct and the code should run just fine.

Ideally your Gcode should contain the G90.1 or G91.1 (as appropriate) and this is perhaps a failing of your CamBam post processor.
