Hey guys, I've got an acrylic i3 kit that's been upgraded with the 2020 frame. I just bought some TMC2130 drivers and a Titan Aero extruder. I'm trying to get the VREF setup for the drivers but I can't find any info at all on the nema 17 4.8kg/cm stepper motor that FT uses for the Y axis on the i3 printer kits. They're not for sale anywhere and the Google Drive only has info on the smaller 2.6kg/cm motors.
I do know from the Teaching Tech YT video that the TMC2130's need RMS current and not rated current but he gives the formulas for that. I need to know the rated current for this motor so I can get it set properly.
I can get the Z axis to move and home and the X and Y to move but using sensorless homing the X and Y don't do anything. They just make noise and then it says it's homed.
