To do this manually, put a multi meter to the ground pin of the Motor output (next to the 3 empty holes) and the other wire to the Vref hole/pin and check the data sheet again where Vref has to be measured since that changes even from version to version of the board layout.If you don't have software control over the driver you have to adjust the resistor manually. Lacks some options and adds some and ultimately it'll be up to the I'd rather not call 2209 to be better in every way than the 2130. So I went for the later TMC 2209 (In my opinion a better choice in every aspect to the TMC 2130 and even tho the same hint of 1.2A appears but the RMS is at 2A so it works.)ĮDIT: Teemalut, the library creator clarified a few points that I misinterpreted in the documentation:Ĭurrent rating doesn't limit your choice of stepping mode. ![]() ![]() Motor Phase Current max 2A RMS, 2.8A Peak Resistors), but the SilentStepSticks can only be used up to 1.2A RMS." "The maximum settable motor current is 1.77A RMS (0.11Ohm sense That means the TMC 2130 would work but wouldn't be able to run in stealth mode but would work since. In my case:ġ7hs4401 the motor has 1.7A "Rated Current". checking the data sheet of the stepper motor for the Imax current.To take advantage of them, my 6 step guide to hopefully safe you a day or two working through the Trinamic website for a quick and run. with the AccelStepper arduino library but would miss out many great features. EN can be pulled to a GND pin to work f.e. In short, a driver board like the TMC 2130 only need +5V and GND, a Digital pin for DIR and STEP. Just because I still didn't knew what I was doing after the answers even tho they are helpful, a bit comprehension in knowledge for beginners, since the driver board differentiates f.e.
