Hi All;
My configuration is:
-D510MO computer.
-Ubuntu 10.04 and EMC2 2.4.5.
-Pico Systems USC in non servo mode.
Plan to go servo and HOME-USE-INDEX after Homing is working.
-Limit switches only (used for homing).
I am having several problems with Homing as follows:
1- I want to home the Y (axis 1) at the Max end to avoid the
chance of the vice ramming the Z axis ways. This Homes fine but
always moves to the 0 position to finish the Home, defeating the
purpose.
2- I tried moving the Y (axis 1) Home to the Negative end but
this ignores the limit switch and stalls at the mechanical stop.
The Home settings for this:
MIN_LIMIT = 0.0
MAX_LIMIT = 10.7
#HOME_SEARCH_VEL = -1.0
#HOME_LATCH_VEL = -0.1
#HOME_FINAL_VEL = 1.0
HOME_SEARCH_VEL = -0.05
HOME_LATCH_VEL = -0.005
HOME_FINAL_VEL = 0.05
HOME_IGNORE_LIMITS = YES
#HOME_USE_INDEX = YES
HOME_USE_INDEX = NO
HOME_OFFSET = -0.08
#HOME = 10.7
HOME = 0.0
#HOME_SEQUENCE = 0
3- The X and Z axis Home fine but stop the homing
process with a EXCEEDED SOFT LIMITS error.
Also the final "HOME = " setting is move to before the
axis position is zeroed and the Home indicator is turned on.
Their Home settings follow:
X
MIN_LIMIT = 0.0
MAX_LIMIT = 23.65
#HOME_SEARCH_VEL = -1.0
#HOME_LATCH_VEL = -0.1
#HOME_FINAL_VEL = 1.0
HOME_SEARCH_VEL = -0.05
HOME_LATCH_VEL = -0.05
HOME_FINAL_VEL = 0.1
HOME_IGNORE_LIMITS = YES
#HOME_USE_INDEX = YES
HOME_USE_INDEX = NO
HOME_OFFSET = -0.1
HOME = 0.0
#HOME_SEQUENCE = 2
Z
MIN_LIMIT = -14.1
MAX_LIMIT = 0.0
#HOME_SEARCH_VEL = 1.0
#HOME_LATCH_VEL = 0.01
#HOME_FINAL_VEL = 1.0
HOME_SEARCH_VEL = 0.05
HOME_LATCH_VEL = 0.005
HOME_FINAL_VEL = 0.05
HOME_IGNORE_LIMITS = YES
#HOME_USE_INDEX = YES
HOME_USE_INDEX = NO
HOME_OFFSET = 0.05
HOME = 0.0
#HOME_SEQUENCE = 1
Does anyone see or know the problem?
Thanks
Don
