Gentlemen,
I am using a ppmc encoder board.
The parameters in my ini file look like this
HOME = 0
HOME_OFFSET = 0.0
HOME_SEARCH_VEL = 0.4
HOME_LATCH_VEL = -0.01
HOME_USE_INDEX = YES
HOME_IGNORE_LIMITS = NO
I am using the third sketch from the html page you referenced.
I can allow the axis to move to the home switch or I can actuate
the switch by hand with the axis away from the switch. I get the same
results either way it just does it in different spots in the travel of
the ball screw.
When I start the machine the axis postions are zero. When I home
an axis the machine moves in the positive direction until the switch
is activated. When the switch is acitvated the axis reverses direction
and moves very slowly until it reaches the index pulse. The machine
then moves to the startup position. The control does not set the axis
position to zero when it sees the index pulse therefore it uses the
current axis zero position and moves to it. It does turn the axis
home signal on.
It has homed correctly on an axis. I then moved the axis and
restarted the machine and the home cycle did not finish correct. I
changed no parameters between the home cycles.
dmesg gives no error reports. I looked at it prior to the homing
cycle and after the homing cycle. There are no messages generated by
the homing cycle. The last line in the dmesg report was for a thread
created. If I home the machine a second time I get as follows in the
dmesg report
ERROR: end of move in home state 5
thanks
Stuart
