I realise that I'm probably asking questions that will make people want to pull their hair out. Once I get it, I'll be able to just leave it running.
I've downloaded those files, and there are 3 sets. My miner is an S17-53T so I'm not sure which of these to use, as they don't match the filename precisely?
SD_S17+ should be only for S17+ (not sure if it is for T17+ too). I realise that I'm probably asking questions that will make people want to pull their hair out.

SD-X17 should be for any S17 and S17 Pro.
And T17 should be for T17 only (not sure if it is for T17+ too).
