[16:42:50] <skunkworks_> zlog,
[17:11:40] <skunkworks_> nope - looks like the backlash is in the ballscrew area.. Think we are going to live with it for a while..
[17:11:56] <skunkworks_> unless dad decides to dig into it..
[17:12:21] <skunkworks_> seems you pretty much have to remove the z axis to get to the ballscrew
[17:13:56] <skunkworks_> it is around .0015 it seems
[17:44:47] <tinkerer> is the staff back from the weekend?
[17:46:12] <pcw_home> skunkworks_ does the backlash vary with location? (wear)
[17:51:30] <skunkworks_> doesn't seem to by much - it seems to be pretty consistent over the whole travel..
[17:52:00] <skunkworks_> like the preload was botched maybe
[17:52:21] <skunkworks_> it isn't end bearing (the ball screw doesn't move up and down)
[17:55:36] <pcw_home> is there a preload washer or some such?
[17:57:38] <skunkworks_> don't know for sure. pictures look like there are 2 ball nuts separated by a spacer. but without actually getting in there - I don't know
[17:57:59] <skunkworks_> (don't have explosions of the machine)
[18:01:57] <skunkworks_> and it takes some elbow grease to get to it.
[18:15:08] <pcw_home> sounds like a project for a rainy weekend
[18:26:12] <skunkworks_> yes
[18:34:29] <pcw_home> wonder if the Z axis weight make the backlash irrelevant (and least for small tools)
[18:38:34] <skunkworks_> it is counterbalanced... :)
[18:38:50] <cradek> saw some of the weight off!
[18:39:47] <cradek> er no, probably want to add some
[18:39:51] <cradek> so it goes up
[18:41:07] <skunkworks_> heh
[18:41:27] <skunkworks_> it is slightly heavier going up
[18:52:56] <skunkworks_> http://www.practicalmachinist.com/vb/cnc-machining/ballscrew-rebuild-whose-done-228102/
[18:53:00] <skunkworks_> something like that
[18:53:35] <skunkworks_> http://www.practicalmachinist.com/vb/attachments/f21/35912d1309274318-ballscrew-rebuild-whose-done-p6260014s.jpg
[18:58:17] <pcw_home> Are those through-bolted to clamp the preload spacer?
[18:58:26] <skunkworks_> no clue
[18:58:59] <pcw_home> not obvious from the picture
[18:59:17] <skunkworks_> they are talking about resizing the balls - but i bet they are adjustable with the spacer maybe.
[19:01:41] <pcw_home> not sure if theres an advantage of ball resizing on dual nuts with adjustable preload
[19:01:52] <pcw_home> Hmm, one of our new pullets wasn't
[19:19:33] <skunkworks_> we can only have hens here
[19:24:48] <pcw_home> They never seem to sex them perfectly, we have had this happen pretty often
[20:22:50] <skunkworks_> pcw_home, I did have the 7i69 not get found
[20:27:53] <skunkworks_> the computer has been up for weeks though.. and i am still powering everthing from the 7i80
[20:31:48] <pcw_home> That should be OK (if the 7I80 5V is a couple amps) I think all outputs on on a 24 channel OPTO 22 rack is 300 ma or so
[20:32:41] <pcw_home> might check the 5V at the 7I69
[20:42:25] <skunkworks_> first time it has happened
[20:44:50] <pcw_home> so you started linuxcnc and the 7I69 was not found?
[20:46:56] <skunkworks_> yes.
[20:47:39] <skunkworks_> unplugging/plugging the 7i69 fixed it.
[20:48:27] <pcw_home> restarting linuxcnc didn't fix it?
[21:04:49] <skunkworks_> no
[21:04:58] <skunkworks_> pcw_home, no
[21:09:00] <pcw_home> do you recall if power was on (red light on 7I69)?
[22:46:10] <skunksleep> pcw_home: there was a light on the 7i69.
[22:47:38] <pcw_home> strange, sounds like it was wedged but not sure, I've never seen that
[22:49:50] <skunksleep> I will keep an eye on it.
