Gentlemen,
The Cinci was set up to use home switches. I am now using the limit
switches for homing. I did this to better match the homing cycle to other
machines in the shop.
I have the soft limits set.
During this I learned something. I have been trying to "fix" the servo
amps so when I hit a hard limit they just disable the direction the table
was moving when the limit switch was contacted. I found the servo amps are
working correct. It is EMC2 that is shutting the servos off when I hit the
limit switches. I much prefer the servos to remain on. This is not a problem
on the X, Y or Z axes. The problem is the A and B axes. Given the weight of
the head and the reality that there are no brakes on the motors:
if the head is tilted enough to hit the limit
switch
and
the servos turn off
then
the weight of the head will cause the head to
coast (fall) until the pinion gear disengages from the rack.
This is not a huge problem and should be almost nonexistent. I will know
and do not feel comfortable with this as a possibility.
I have disengaged the limit feedback for each axis. I am just using one
limit hooked to the home feedback. This allows homing.
My question is this (and maybe I have just overlooked it in the manual).
Is there a pin out of EMC2 that will disable the
motion in the direction of motion instead of shutting down all the servos?
thanks
Stuart
