Looks like you should be able to use that driver. I assumed the C8S would have the same size driver as the C8, but it instead has a 19.6mm as discussed here: Thorfire C8S question….
I really like the Bistro firmware in my C8. It’s highly customizable and no need for a turbo timer since it has thermal calibration. But I see that RMM has added several new firmware options. Choices, choices…
