General Mach Discussion / Mach3, MPG, Brains...wait...is this minus a plus ?
« on: August 06, 2010, 06:27:18 PM »
Hi there.
I'm in a little predicament here. Let me be as narrative as concise :
My Mach3 demo runs fine...loading, some G-code, turning the 3-axis motors drive offline to do some tests...
I have this homemade Modbus-RTC m.p.g plugged in, calibrated, activated, and a dedicated brain in Mach3 running... Let's look at it in realtime...(attachment #1/3)
Rotating the knob clockwise : (attachment #2/3)
Then counterclockwise : (attachment #3/3)
Great ! The MPG1 Count internal variable is reflecting my mpg's clicks...
BUT : why does the tool/program combo always moves FORWARD while in Shuttle Mode ? Shouldn't I be able to trace back on the toolpath when I turn the MPG knob backwards (and MPG1 Count is obviously decrementing)
What setting did I miss for my "MPG1 Count" deltas are always being seen as positive ?
Help ? Someone ? Anybody ? Pretty please ?
