I just tried the fix on my lathe, and it looks worse. I always got the klunk the first time I homed, but it would be OK if I did subsequent homes.
I use a home switch and an index pulse. It moves to the home switch, then reverses slowly to find the index pulse. It sets the X value to be the current radius (80.54mm), then moves to 70. Scope picture here http://filebin.ca/hugkmx. It klunks after it finds the index pulse. My config... # X axis [AXIS_0] TYPE = LINEAR MAX_VELOCITY = 15 MAX_ACCELERATION = 40 BACKLASH = 0.000 INPUT_SCALE = 2048 OUTPUT_SCALE = 1.000 OUTPUT_OFFSET = 0.0 MIN_LIMIT = -53 MAX_LIMIT = 81 FERROR = .06 HOME = 70 HOME_SEQUENCE = 0 HOME_OFFSET = 80.54 HOME_SEARCH_VEL = 2.0 HOME_LATCH_VEL = -0.1 HOME_USE_INDEX = YES HOME_IGNORE_LIMITS = NO MAX_OUTPUT = 1.0 > -----Original Message----- > From: Jon Elson [mailto:el...@pico-systems.com] > Sent: Tuesday, 17 November 2009 5:53 AM > To: EMC developers > Subject: [Emc-developers] klunk on homing to index - YES! > > Thanks to Chris Radek for fixing that klunk when homing to > index.
