Title: Funny (or weird?) behaviour with backlash compensation enabled (video)
Post by: FXC on February 21, 2010, 04:45:36 PM

WTH is this? Apparently, the backlash comp happens at the end of a move or at some point in the midst of it. Take a look (and listen) at this short video I just uploaded:

<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/roSD1O_1LJQ&hl=en_GB&fs=1&rel=0"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/roSD1O_1LJQ&hl=en_GB&fs=1&rel=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>

I think I found another post describing the same problem, however no solution has been posted in response to it.

Don't know what is going on there....
Backlash is done when a change of movement occurs, one axis or in a combination move. Using version 033 and have no problem here.
What Mach version are you using?
Any problems with the axes when backlash comp is not used?
What were you doing when you took the video to make the axis moves?
Are you using a SS or PP?
How about some more info .......
