What is strange is that pressing Machine (F2) does not clear the alarm. (That won't close the alarm notification window, you have to click the X on that window to make it go away.)

Thanks for all the input. A few things in case it hasn’t been clear... 1) I don’t (currently) have a PID involved at all (position-mode steppers with encoders only). 2) If I set FERROR=2 and MIN_FERROR=1, homing DOES complete successfully. 2) Pressing estop after the following error, and then trying to turn Linuxcnc back on from there does NOT help, the error persists. Only exiting and restarting Linuxcnc clears it. The Halscope trace of: hm2_7i43.0.stepgen.02.position-cmd, hm2_7i43.0.encoder.02.position, hm2_7i43.0.encoder.02.index-enable, axis.2.home-sw-in with trigger of axis.2.f-errored can be seen here: http://bgp.nu/~tom/pub/enc2.png I’m happy to help debug a (even obscure) bug if you want, but it sounds like I’d be better off using velocity mode and PID ANYWAY, and so should probably do that instead of what I have.

If you DO want me to test this, please remind me how I go about getting/building/running it. It has been a while since I have grabbed branches. This machine runs from the standard release model, so I assume I will need to incant git (all of which I tend to forget within a week of using it for some reason)… -Tom > On Jun 20, 2017, at 2:19 PM, andy pugh <bodge...@gmail.com> wrote: > > On 20 June 2017 at 18:47, Sebastian Kuzminsky <s...@highlab.com> wrote: > >> It looks like it'd be easy to add a ".raw-position" pin to the hostmot2 >> encoder. > > > Does homing use the accumulated counts in the counter after index as part > of the homing offset?
