No dice. Increasing the FERROR limits didn't do much of anything except
once I reached a certain point, which was not a very large change, the Z
axis licked up and the stepper motor let out a rather loud squeal.
This sounds like the offset being applied is unexpectedly huge.
What is output of the lincurve?
Since the X axis hasn't moved, and the lincurve values for the X axis at
zero are this:
setp lincurve.0.x-val-00 0
setp lincurve.0.y-val-00 0.000
It should have a 0.000 output.
I just thought of something though. Look at this again:
net z-raw axis.2.joint-pos-cmd offset.0.in
net z-corr lincurve.0.out offset.0.offset
net zpos-cmd offset.0.out
net zpos-fb offset.0.fb-in
net z-pos-fb-offs offset.0.fb-out axis.2.motor-pos-fb
I think something is missing here. That would be the either the
axis.0.motor-pos-cmd or axis.1.motor-pos-cmd feeding lincurve.0.in the
actual X axis position. This might be a little tricky since I have the
two drives slaved as the X axis like this:
net ypos-cmd axis.1.motor-pos-cmd => axis.1.motor-pos-fb
net xpos-cmd axis.0.motor-pos-cmd => stepgen.0.position-cmd
stepgen.1.position-cmd
Would I net lincurve.9.in to xpos-cmd or ypos-cmd? Or would I net to
something else?
