When I connect engines to board it moves but when I use belt to move caret or just touch a pulley engine stop moving. I try to set Vref using stepper driver screw but value oscillates around 0.10 - 0.14 V.. "/>
Jul 19, 2019 · Post # 3 Thursday, July 18, 2019 11:20 AM. eliwong_git You need to set the current of Y to 650mA in the firmware, and the temperature will be around 50 degrees, but there is no lower than this! Wow ... TMC2209 650mA (0.65 A) Irms are around 0.92 A Imax per phase. That is a lot for a 0.84 A stepper motor like a JK42HS34-0844 on a Ender-3.. The TMC2208 is an ultra-quiet VREF calculator with a two-phase motor drive. Its continuous drive current stands at 1.4 A, reaching 2A. The voltage range is between 4.75 V to 36V, and it boasts 256 subdivisions. Check at Amazon Additionally, it's compatible with most 3D printers available in.
The guy explains in the video how to calculate the Vref and the X_CURRENT value of Marlin. RMS current = Max current / 1.41 = 1.3 / 1.41 = 0.92 Vref = (RMS Current x 2.5) / 1.77 = 1.3 V 90% Vref = 1.17 V // to avoid maximum power in the motor X_CURRENT = 1170 mA // magic, I don't know why the guy of Teaching Tech does this convertion

Vref TMC2209 calculating. I was wondering if I did somewhat of a good calculation for this stepper driver. According to what I found online I got to get the Imax of my stepper motors (I found that my X,Y,Z are max 1.5A, my E stepper I can't find it online so I'll assume 1A max) Got to work with Irms -> Imax / 1,44 and based of this I can get ...
For my old stepper driver (A4988 based Stepper), the I_max is calculated with: Imax = VRef / (8*Rs) I didn't know the Rs of my driver, but the author of the post did have similar values, therefore I just assumed my Rs would be 0.1 Ohm, too. Afterwards, you can calculate the new Vref for the TMC 2208 with following formulas: Irms = Imax / 1,41
