I am using version emc 2.1.7 and tried to use the comp file feature and got the following results. When I homed the axis using that file the axis began moving in the direction of the limit switch but before it got there it reversed at full speed and was heading toward the opposit limit. When I hit E stop and it didn't stop. I had to hit the main power switch to the stepper driver to get it stopped. Upon reapplying power to the driver the motor on that axis didn't move but made a strange high pitch "singing" sound. After closing emc2 and then reopening it,the motor sounded normal (a5khz hum is normal when it is motionless), I was able to jog the axisl, however when I tried to home the axis it repeated the runaway.
Resetting the ini file back to using backlash comp the system performed flawlessly. Does anyone know what is going on? I have included the pertainent section of my ini file and the comp file below: Jack Ensor #+ First axis X [AXIS_0] TYPE = LINEAR HOME = 0.000 MAX_VELOCITY = 1.5 MAX_ACCELERATION = 2.0 STEPGEN_MAXVEL = 1.7 STEPGEN_MAXACCEL = 2.2 #BACKLASH = 0.0024 COMP_FILE = comp1.fil COMP_FILE_TYPE = 0 INPUT_SCALE = 2500 OUTPUT_SCALE = 1.000 MIN_LIMIT = -13.0000 MAX_LIMIT = 13.0000 #FERROR = 0.050 #MIN_FERROR = 0.010 HOME_OFFSET = -13.0 HOME_SEARCH_VEL = -1.0 HOME_LATCH_VEL = 0.05 HOME_USE_INDEX = NO HOME_IGNORE_LIMITS = YES HOME_SEQUENCE = 1 comp1.fil -12.5000 -12.5000 -12.49970 -8.0000 -8.0010 -7.9970 -5.0000 -5.0010 -4.9970 -3.0000 -3.0010 -3.0030 0.0000 0.0000 0.0030 3.0000 3.0000 3.0030 5.0000 5.0000 5.0030 8.0000 7.9995 8.0040 12.5000 12.5000 12.50045 ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
