Closed loop duet expansion BISS-C/SSI Absolute Encoder Support
-
Will the upcoming single axis closed loop board support SSI/BISS-C encoders as the feedback mechanism? at least for position/velocity if not for motor commutation?
-
@lee7670 no, at least not initially. Do you have some examples of these encoders and/or motors with the encoders built in?
-
No, not built in, but I have a couple custom axes with linear BISS-C/SSI encoders that would be really nice to close the loop on without janky external solutions like I have been using.

Here's a reference of one of these encoders.

Here's a Reference for SSI (BISS-C is backwards compatible to SSI)
