Please remember to include the following details to help troubleshoot your problem. 77A) / 2. Actually, the TMC2209 is a newer model compared to the TMC2208 and comes packed with many additional features. Connect the voltmeter + to VREF, [-] to the GND and read the value. Plugging these numbers into the driver’s formula, we get: V REF ~=1. 6 / 9 6、Microstep Setting 7、Drive Current Formula 1、Vref：0. Feel free to bring your questions, related or un-related, you all dec TMC2209 SilentStepStick Pinout. 1224. On some stepper motor drivers the maximum current (e. Follow this guide and become your own Vref calculator! Rotate the potentiometer counterclockwise to increase the Vref voltage and the drive current can be increased. 2V ±0. 8V 2A). If the vref is within safe limits, I don't see why you Inom = Irms = (Vref * 1. It is the same formula for the TMC2208, TMC2209 and TMC2225 drivers: IRMS is the root mean squared motor current: I RMS = I MAX / sqrt(2) On the Creality mainboards, the sense resistors are 150 mOhms. Microstep Setting. 41 Do I take 80% to 90% of this or of the finale vref? Vref = (Irms * 2. Let's compare the two by looking at the The best way to set the motor current is by measuring the voltage on the Vref pin (02. txt) or read online for free. TMC2208 Vs TMC2209. 5V) and adjusting the voltage with the potentiometer. 75-28V, 2. 0&3. After you find out the model of the stepper drivers your Ender 3 came with, the next course of action is to find the documentation for the stepper driver, which includes the formula for calculating the VREF value, as each stepper driver requires a different formula. Question: how do i set the required vref on the fly (using software)? Is it something that i need to do manually, like a gcode command? Any help is greatly appreciated. Rotate the potentiometer counterclockwise to increase the Vref In the following image, you can see the basic application block diagram of TMC2209 IC.
