iirc you have lathe under emc
does your machine have some mechanical problems like backlash, screw comp?
no it is about perfect
no backlash comp

cradek: we have haas lathe that has cone compensation(?) as a parameter in tool table and I wonder if this is proper solution for emc if we add it someday
why in the tool table? it would apply equally to all tools
that why it makes me wonder
simmilar to screw comp I think
by "cone compensation" do you mean compensation for X and Z not being perpendicular?
yes (which is properly fixed with a scraper)
[19:03:56] <jepler> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?ContributedComponents#millkins_trivial_kinematics_extended_by_XY_skew_correction
if there's a software fix it's simply this adapted to be XZ instead of XY
yes but another wise guy said that skew doesn't have to be linear
and I don't have idea how to easly do this
(how this easly can be done)
a very worn machine will have an arc, because wear is more in the center
that too is fixed with a scraper
cradek: what do you mean by scraper?
[19:09:20] <cradek> http://en.wikipedia.org/wiki/Hand_scraper
micges: I think cradek is saying to repair the broken lathe, not try to fix it in software
yeah, IMO any software 'fix' for slideway wear is a fool's task
cradek: that's opinion is what I needed, thanks
I'm surprised you feel that way :-)
cradek: How time consuming is it to straighten a way with a scraper? That sounds like a multiday job with really tired arms...?
Dave911: depends how far out it is, and how good you are with the scraper, I'm sure
if it's bad, I think a way grinder can be used first
there's a whole art to it and I don't know it :-)
I'd like try that someday ....
At the York, PA cabin fever show last year there was a guy there demonstrating the use of a scraper to correct machine errors but the crowd surrounded him and I couldn't see what he was doing..
what is BIAS in the [AXIS] section of a servo config?
jthornton: it appears that pncconf uses this for pid.N.bias
actually, core_servo.hal (m5i20 and others) and hm2-servo.hal (all hostmot2 systems) use [AXIS_#]BIAS for the same purpose
the function of bias is explained in the pid manpage
