I may be having a similar problem. I am using home to index on a ordinary rotary servo machine and the first time I try to home after starting Linuxcnc, one axis always seems to set a following a error, If I try to home it a second time it will home fine? I am not using bldc, so it might be possible that your following error on homing problem could be completely unrelated to bldc using index to initialize. What is more odd is that I only seem to have a problem with one axis (out of 4) doing it. I think Andy might be on the right track with thinking it may have something to do with the counts resetting to zero when the index is tripped for the first time. But the question still remains, what to do about it?
----- Original Message ----- Hello everybody, I would like to somehow Home the bldc linear motor using axis GUI home button. I am using bldc in qi mode, so it has to be homed using bldc.init (separate from axis GUI). But on the other side bldc and axis has to be homed simultaneously because of index-enable signal and latching of encoder value. So i have to somehow trick the axis. Any idea how could i do that? One of my idea was to use the axis.homing -> bldc-init to start the bldc homing and at at the same time temporary change the axis.f-error-lim value (so that axis homing won't stop because of following error). But i could not find the axis.f-error-lim INPUT pin. Is there some other option to temporary change the f-error limit value? Is there any other option how to home the axis and bldc?
