I know it doesn't support UART mode but you still need to consider MS3 switch if using a 2209 module that has SPREAD signal on that pin. eg: https://wiki.fysetc.com/Silent2209/#v30-hardware-connection V3.0...

From the datasheet: > 13 STEP/DIR Interface The STEP and DIR inputs provide a simple, standard interface compatible with many existing motion controllers. The MicroPlyer step pulse interpolator brings the...

The resistor connects Sprd to +5v - permanently enabling StealthChop mode ([https://github.com/makerbase-mks/MKS-StepStick-Driver/blob/master/MKS%20TMC2209/MKS%20TMC2209%20V1.0_001/MKS%20TMC2209%20V1.0_001%20SCH.pdf](url)). It'll work fine but I'd leave MS3 switch OFF to avoid shorting the UART signal to ground.

AFAIK it interpolates a full step to 256 microsteps therefore if you supply 64 microsteps to the drive it'll "expand" each 1/64 microstep to 4 small steps (256/16). Ideally, you...

After a day of messing around with this - this solution worked for me. In Firefox address bar enter '_about:config_' Then search for 'XDG'. It'll show '_widget.use-xdg-desktop-portal_' - change it...
