Motion accuracy of stepper motor SM4247
The motor motion accuracy was tested with latest version of our stepmotor driver SMD-4.2. The examination was done in microstepping mode 1/256, during 2 full steps. The displacement error is below 0,03 degrees, that means less than 1,8 arc minutes. The test curve is below.
