Just had mine delivered.  I cannot get it working with the ZEC pool's for Suprnova or Slushpool.  Error is something related to "extranonce"..

On Antpool, the "dashboard" after 20+ minutes shows nothing - so although am getting some shares accepted, I can't see assurance from Antpool's dashboard that they are being recorded..

The fact that this doesn't work on all pools is a bit disconcerning!
