Ok, I tried with acceleration of 1. I'm working with mm so it is 1sec for
1mm/sec. It is VERY slow.
The problem persists.
This is what happens:
The 1st axis accelerates as it should.
When the 2nd axis changes direction, the firts axis stops emidiatly.
The backlash compensates for the 2nd axis (I guess that the compensation
process dose not accelerates and decelerates but startst and stops emidiatly
with the correction velocity).
When the backlash is done the 1st axis imidiatly returns to its previous
velocity.
I think that you may have a problem with the algorithm. Maybe you should
break some moves (which have a direction change) into several seperate
moves.
As I anderstand the CV algorithm defines the way in which the path is
generated at the end of each command.
Thanks, Isak.

Isak:
. You need to decrease your acceleration to about 1 or less to do this
test. Does the axis slow down to stop, then backlash correct, then
accelerate again? I'm just trying to figure out if the algorithms are
working correctly... An acceleration of 10 is NOT small, it means 1 sec to
get to 10 inches per second. While this is not overly fast, it may be too
fast to tell me what I need to know.
Thanks,
Art
