Hi,
I just reveived one TMC2209 v2 from watterott and wanted to use and configure it in legacy mode for my MKS Gen L Ender 3 Pro (extruder driver).
If I try to set VREF, i can only set values from 0 to 0.09 V. Yes, I measured on the correct pin (middle one), and yes, 24 V are on the machine.
Why isn't the VREF in normal ranges?
