Title: Abnornal Refall Light
Post by: inivator on July 27, 2008, 06:14:29 PM

When I do a Ref-All on the axis, I get a flashing normal/abnormal lite.  What caused this condition?????????????

Hi, Inivator

The normal/abnormal button will flash if you've changed some settings in Mach, I haven't seen a complete list anywhere.

If everything is acting normal, You can double click on the button and re-set it to be your normal state.

Hope this Helps, Chip

Just double click on it to set it as normal condition, probably its flashing because your normal condition previously was using an Un Refereced system, now you are doing the referencing Mach is seeing something different so is wondering if its normal or not, as it is you need to tell Mach it is :)

Nope, just tune each axis to what it runs best at, Mach will use different settings no problem in its calculations :)

SINCE I HAVE THE LIMITSWITHES WORKING, NOW ANOTHER PROBLEM HAS ARISEN.  I'M DONG MULTI-DEPTH CUTS IN PLYWOOD, .060 AT A TIME, BUT NOW I AM LOSING POSITION IN BOTH X AND Y AXIS.  I'M ONLY GOING .182 DEEP TOTAL AT A FEEDRATE OF F4, THE FIRST TWO PASSES SEEM OK, THEN I START LOSING POSITION.  I HAVE CHECKED FOR BACKLASH, AND  HAVE NONE.

Hi, Inivator

It could be a number of things, Acceleration set a little to high, If there are any G00 moves Velocity to high, Power Supply volts or amp's not sufficient, Current on your stepper board set low.

Tell us about your setup.

Thanks, Chip

NOTHING IN THE SET-UP HAS CHANGED.  THE POWER SUPPLY AND BOARDS ARE THE SAME SINCE DAY ONE.  THE ONLY CHANGE THAT I HAVE MADE IS TUNING OF THE MOTORS.  ALL ARE TUNED TO ABOUT THE SAME SPEED AND ACCELERATION.  I HAVE SET THE LOOK-UP TO 200, IT WAS 2.  I HAVE NOT RUN THE MACHINE SINCE THE LOOK-AHEAD WAS CHANGED.  I HOPE THIS WILL HELP THE PROBLEM..

Hi, Inivator

Have you done these short segment type files in the past.?

Is Mach setup in CV or Exact Stop mode in Config, General Config.?

A Look Ahead of 200 is big and probably won't help if your in Exact Stop mode.
