I'm having trouble getting the new 2.8 external offset functionality to
play nicely. Most of the (known) steps are working (as observed in the
hal watch screen):
- axis.a.eoffset-enable is set true.
- inputs (step up & down) generate appropriate values in
axis.a.eoffset-counts
- offset counts generate an (at least for first approximation)
appropriate value in axis.a.eoffset-request
- but the requested value never shows in axis.a.eoffset
OFFSET_AV_RATIO is set to 0.5 (just a swag for now).
other configuration values for this axis are cribbed directly from the
generic stepper example. The stepper motor responds appropriately to jog
commands.
I'm sure there is a (blindingly obvious) step I'm missing, can somebody
aim me in the right direction?
as always, thanks
lloyd
