Here's what I'm trying to do...

CurrentPosX = mc.mcCntlGetDistToGo(inst, 0)
CurrentPosY = mc.mcCntlGetDistToGo(inst, 1)

if CurrentPosX > LastPosX and CurrentPosY > LastPosY then
   --Do something

LastPosX = CurrentPosX
LastPosY = CurrentPosY

So the question is...If I put global variables LastPosX and LastPosY in the screen load script, will they be visible to the PLC script?  Or...Will LastPosX and LastPosY retain their values from scan to scan?  For instance, if I set LastPosX to 4.123, will it be nil on the next PLC scan or will it still be 4.123.

I don't want to pirate Mach3.  Can anyone point me in the direction of a solution?  I accept that I got a lemon, but I got the steppers, lead screws, table, etc for a decent price, even if the controller doesn't work.  My confusion is that the serial port connection even supplies the power to the spindle.

Try the icon in the toolbar with the black/white squares, which toggles the toolpath on and off.

Hi. I would like to make LED's on my panel to light up to indicate movment on each axis. So when my x-axis moves in positive direction I want 1 output to be activated, both if
axis are started by an G-code or by me hitting X+ jog button or using my jog wheel... Same for each axis and direction.
I really tryed to do this, but no luck so far.

Can some one help me with this one ?

If you are using a laptop then you need a motion controller such as the ESS or similar (Laptops are not supported for Mach3 use with the parallel port).

I do believe I have a problem with Mach3 . When jogging continuously  it will move .500 TO .750 of an inch then move another 3/4 of an inch and it looks like the motor jumps . It dose not move as smoothly as I would like . Motors make no noise. Now in Mach 3 when I do the driver test it is all over the map Too fast too slow excellent too slow.Never stays steady for more than a second or two. I have tried low gain medium gain high gain factory gain .And tuned the motor to be quite on all settings and no help I also tried encoder settings from 500 to 2000 and no help ,anyone have any suggestions how to make it run better?Or should I bite the bullet and buy a smooth stepper motion controller. My current set up is a c-10 BOB 4 Gecko 320x set at 500 encoder line count low gain 256 following error. 1x step. Laptop running windows xp . Any help is much appreciated thanks guys.

50 mm is actually a good size. I want to make some simple puzzles for the grandkids, maybe 10 or 12 pieces. They can put it together right or go a little Picasso. Cheesy

I downloaded and installed the Mach4 demo, and it fired up ok.  Clicking the MDI tab prompts for a password, but the documentation doesn't mention it. Any suggestions?
