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.

OK, so stepgen also can compute following error. Without encoders, it is only possible if steps can't be issued fast enough, but with encoders, then there are other ways to create a following error.

Thanks,

Jon
