General Mach Discussion / Mach 3 Mist Control Problem

« on: March 11, 2006, 08:18:26 PM »

Using Mach 3 I can't get it to turn on tne Mist or Flood relays.  I have the proper pin configuration (pin #, Active High on output 1 & 2)  on the diagnostics screen, the leds light as they should for outputs 1 and 2, but the port is not sending a high signal to the board.  I double checked this with a logic probe -- they stay low even though the leds light up.  What am I doing wrong?  These functions work OK under MACH2.

General Mach Discussion / Homing in Mach 3

« on: March 08, 2006, 09:17:30 PM »

I've been using Mach 2 successfully, well ... that's exagerating since I'm a beginner, but everything seems to work as I expect it on Mach 2.  Anyway, when I switched to Mach 3, the homing function no longer works correctly.  The axes drive to the home switches, stop and reverse as normal, but they do not back off far enough to clear the switches.  Is there a configuration item I've missed?  The axes need to back off just a little farther to clear the switch.  I thought Mach 3 reversed and ran till the switches open -- true?  If that's the case, why isn't mine clearing the switch?  In diagnostics mode, the LEDs stay lit continuously once the axis reaches home.
