Hello,
I have a small machine which I have had setup and running with other software
for a year now. I recently tried EMC and am having some issues. From what I
have read, support for Homing is somewhat recent. I am running the latest
version, or atleast there are no updates showing. (I installed from the LiveCD)
When I try to home the machine, it runs at full speed and bashes into the hard
stop, ignoring the home switch. The switch does work, and I have tried
inverting the signal in stepconf, but no luck.
The machine homes fine when using another software package, but I really prefer
the flexible concept of EMC.
My axis is setup as follows:
[AXIS_0]
TYPE = LINEAR
HOME = 0.0
MAX_VELOCITY = 0.3
MAX_ACCELERATION = 0.5
STEPGEN_MAXACCEL = 0.525
SCALE = 10000.0
FERROR = 0.05
MIN_FERROR = 0.01
MIN_LIMIT = -4.375
MAX_LIMIT = 4.375
HOME_OFFSET = -4.375000
SEARCH_VEL = 0.020000
LATCH_VEL = 0.100000
HOME_SEQUENCE = 1
It seems that no matter what i set the SEARCH_VEL to, it runs at full speed (18
in/m)! Is there a simple fix for this? Can anyone tell me what EMC expects
the switch state to be, true when at home, or reversed? Or does it need
Normally Open switches?
Thanks in advance for any help.
