UHF Oozing
I have a rapido 2f with the UHF nut. Previously was using the original rapido, HF with a v6. With PLA, the prints are perfect, but with 'oozier' filaments, like CFPC, or LWPLA, the stringing is a nightmare. I've done all the regular tuning, but my question is do UHF/Volcano hotends require more retraction than compared to non UHF nozzles? To get more filament out of the melt zone?
Is there anything else I should be considering? Like retraction length vs retraction speed.

Sudden bad extruder stepper
My LGX is no longer working, it is on an skr octopus, with tmc 2290s. The stepper is just grinding, like when the wires are backwards. I've tried swapping in a new stepper but it is still grinding. Could it be the wiring? The motor itself? I've also tried a different stepper port on the octopus.
