Now, this is perfectly normal, and with a servo / pid machine the system
knows to ignore the f-error immediately after an encoder reset. What is
puzzling me here is why it isn't working in this case. I think it is
pid's index-enables need to be added to the index-enable nets.
Tom has no pids in this config, he's using position-mode steppers with
encoders.
Where does the following error come from, then?
Jon
A step in the FB position from the encoder and an attempt at an impossible
step in the commanded stepgen position...
All the complexities / workrounds of this position step on index could be
avoided if support for encoder counter that can only clear on index
was dropped.
