About 3D Printer Stepper Motor Driver, FYSETC Upgrade
Specifications #Interface: Step/Dir 1. Configuration: CFG Pins or UART 2. Native Microsteps: up to 1/256 3. MicroPlyer Microsteps: 1/256 4. Logic Voltage (VIO): 3-5V 5. Motor Voltage (VM): 5.5-36V 6. Motor Phase Current max: 1.2A RMS, 2.0A Peak. Therefore, the reference voltage of the driver module should not exceed 1V. At the same time, the driver module must be dissipated, otherwise it will affect the life of the driver module. 7. Internal V- Regulator: enabled 8. RDSon: ≤0.3 Ohm 9. StealthChop (quiet): yes 10. SpreadCycle: yes 11. CoolStep: no 12. StallGuard: no 13. DcStep: no #Motor Current Setting ●The best way to set the motor current is by measuring the voltage on the Vref pin (0...2.5V) and adjusting the voltage with the potentiometer. The maximum settable motor current is 1.77A RMS (0.11Ohm sense resistors), but the SilentStepSticks can only be used up to 1.2A RMS. ●Irms = (Vref * 1.77A) / 2.5V = Vref * 0.71 ●Vref = (Irms * 2.5V) / 1.77A = Irms * 1.41 = Imax ●Vref -> Voltage on Vref pin ●Irms -> RMS (Root Mean Square) current per phase (Irms = Imax / 1.41) ●Imax -> Maximum current per phase (Imax = Irms * 1.41) Note: 1. Vref measures Gnd and the voltage at the middle of the potentiometer. 2. Do not connect the motor when measuring the voltage, otherwise it is easy to burn the driver. 3. Power should be connected when measuring voltage, do not just connect USB power supply. 4. Please pay special attention to directions! Package Includes: ●1 x TMC2208 Driver + 1 x Heat Sink + 1 x Screwdriver
