FuzzyGig,

That link you sent says not to have a queue longer than 128, Following the guide, they all show 1024, If I shorten this, will I need to reflash my ebb36 to reflect the change?

The second thing I see from the klipper documentation says the “qlen 10” is reporting that my device was not set up properly.
