Alden,
I could use encoders with steppers not as an error detection device, but for position information. There are times that I would like to be able to de-energize my steppers and manually move, by hand, my machine. The encoders would act as a DRO at this point and I could re-engage my steppers at any time without loosing position information. I assume this could also be done if you implemented “servoed steppers”.
Are there any plans to create a TinyG on steroids? If so, what’s the timeframe?
