NC Pod / Running from SD card in Mach?

« on: February 03, 2007, 11:35:48 AM »

I have an ncPOD running properly under Mach3.  One of the main reasons I bought a ncPOD was so that I could run G-code directly from the SD card.  I can get it to run fine from the card using the simple ncPOD VB panel.  However, I cannot find a facility to make it run from the SD card in Mach3.  Is it in there somewhere and I'm missing it? If not, any chance of adding this Art?

General Mach Discussion / Wait on Hypertherm XFER output?

« on: January 29, 2007, 06:57:07 PM »

I have a Hypertherm G1000 plasma cutter.  It has an output called XFER, which goes high when then the arc is successful at the beginning of a cut.  I've configured the XFER line to a general purpose input on Mach3.  What do I need to insert into my G-code to wait for this input to go high?  For example, if I want to make a 1-inch cut, what code would I need to add after M03 to wait for this input?

G00 X0 Y0
M03
* would like to insert something here to wait for an input to go high *
G01 X1
M05

Any help appreciated ...

General Mach Discussion / Re: Homing to a switch -- what's the right G-code?

Hmmm ... I'm actually using Mach2, so the input screen is different, but it shows Home X enabled (a check mark).  The xml file that I posted also has the tag;

<HomeX>1</HomeX>

With '1' meaning enabled.  I was suprised to see it disabled in your screen shot.  Maybe there's another setting I'm missing in Mach2?  Perhaps I'll load Mach3 tonight and try the input wizard ... thx for the response!

General Mach Discussion / Homing to a switch -- what's the right G-code?

« on: January 17, 2007, 08:05:57 PM »

I'm a bit confused about how to home an axis to a mechanical switch (and then have Mach reset the DRO to zero when it gets there).  I installed an active low switch and configured it properly in the inputs to Home X.  I tried the following G-codes;

G28 X0
G28.1 X0
G30 X0

My expectation was that the X-axis would travel to the switch, then stop when the switch activated, and finally reset the DRO to zero.  However, it just keeps stepping right past the switch.  I'm *positive* its connected  properly from an electrical standpoint (I watched pin 12 go low on a scope).  Any help appreciated ....
