I'm trying to set up a Creality Sprite Extruder on my Ender 3 Pro without using the kit (installing the extruder alone).
I can see on the Sprite Extruder Pro Kit product page that the extruder operates at 1.4 VDC and 0.8 A.
I'm using TMC2208 and Klipper. How can I set my extruder's driver up so that the provided voltage is 1.4 V? Is it the same as setting the VRef to 1.4 V?
Can it be done in the Klipper configuration (I have a UART set up), or does it need to be done on the trimpot?
