I am running klipper on the SV01pro. Replaced the motherboard with an SKR E3 V3.0 though. The 3.5" btt is just a legacy from a previous mod but also working in Marlin mode.
Using it with klipper screen on an osoyoo 7" Touchscreen. Includes and ADXL345.
Files to print mounts are on printables.com.
Works nice.
I noticed my stupid mistake routing the wire loom through the spool holder! This is changed now.
If there is interest, I can share the printer.cfg and runout.cfg.
Cheers
Armin
