Nice video,informativ my friend!!!!

And no one explains why * 0.71 and why * 2... If anyone is interested: ассording to datasheet I_rms = (325mV / (R_sense + 20mOm)) * (1 / sqrt(2)) * (V_ref/2.5V). Board from video has R110 (110mOm) R_sense resistors. I_rms = (325 / (110 + 20)) * (1 / sqrt(2)) * (V_ref / 2.5), I_rms = 0.7071 * V_ref, so maximum V_ref = I_rms / 0.7071 for this board. And for example if we need a RMS current limit of 1A , then V_ref = 1.0 / 0.7071 = 1.414V

"clockwise' or 'counter clockwise' are the same for whichever way you view the potentiometer (unless from below).

Thank you for the video. But I still need help if you may... I have a 3D printer which is of 24V and I want to replace my Nema 17 48mm (1.5A) with Nema 17 60mm (2.3A) by using TMC2209. I have purchased TMC2209 v4.0 (XinDongWang brand) from AE, is the vref formula still same for this item? Should I use 2.3*1.41=3.24? Do you think using %10 less ampere value (i.e., about 2.10) of the stepper motor would be safer? Thank you very much.

@UzunKamis 6 месяцев назад

Okay, the formula is VREF=Current×1.41, for my case it is VREF=2.3×1.41=3.24 and with %10 safety margin it is VREF=2.3×1.41×0.90=2.92

Hello. What is the VREF setting for 17HS4401S Nema Motor and 1/8 stepper stepper of Tmc2209 stepper motor driver board? Thank you.

@CNCEVOLUTION 2 года назад

17hs4401s has a maximum operating current of 1.7 amperes, so according to the calculation formula 1.7*0.71*2= Vref is 2.4 volts. in most cases, the maximum performances given by the manufacturers are fanciful, so you should use the stepper at a current lower than 1.7 amperes, so depending on the use, for example with a 3d printer, you can use it at 0.8 amperes. it is best to increase the amperage gradually and check how much the stepper heats up. don't forget to use a cooling fan on the driver's radiator. regarding the microstepping, the same formula and the heating check apply

can you make a video on how to wire the entire driver? ive followed every tutorial, read documentation, i cant get this to work for the life of me

@denis2381 4 месяца назад

Which printer?

I burned two tmc2209 :), the power supply was set to 0.5A and yet it burned immediately. I did as in your video.😢

@CNCEVOLUTION Год назад

I'm sorry for destroying the drivers, but if you haven't connected any stepper motor or logic power, the driver shouldn't burn. At power-up the motor supply voltage VM should come up first and then the logic supply voltage VIO. On power-down the logic supply voltage VIO should turned off at first and then the motor supply voltage VM, because the internal logic of the TMCxxxx driver is powered from VM.
