Description
Quick and not so practical dual motor on Y. Its working but be ware of non existing tensioning system. For mount use M3 heat inserts. I used on front 20T Pulley. About configuration. I use klipper so this was easy to setup. Full config in files (m8p v2 + cb1 + omc 17HS19-2004S1 + btt tft35 spi + zorbiter toolhead + usb nozzle cam)
