S42b 1.1 after calibration write 357.7 degrees
Hello boys, i bought two S42B 1.1 for my printer. I test both with a nema17 and as after calibration, on screen write rpm 0, error 0 and degress 357.7. I tried many times to do it again calibration but the result is the same. I watched some presentation videos in youtube and saw after calibration on screen write 0 degress. my question is, is it defective or let me fix it. this video shows the problem please check - and the second problem is, when moving the stepper motor, the speed on the screen is 0. some write something

In the video you never shut the calibration Dip switch off after you calibrate and reboot and turn the Closed loop dip switch on. So first i would be trying that.
Hello, i try, with close loop dip switch OFF, after calibration and i press reset button, on screen the degrees is 0. After this, i turn off the power suppy and i turn the dio switch calibration OFF and the Close loop ON, turn again the power supply on and again write 357.6 degrees. I try and without 3d printer mainboad and is same. I have 2 S42b and present the same. -note, that it works normally I just can not understand what 357.6 degrees means, and if it is normal
I attachment a video https://youtu.be/GVUeH1f0JPE

Try Turning Dip 2 on for Closed loop and 1, 3 and 4 off does that work?
Some of these boards seem to have the dips reversed, my V2 are both like this.
The dip switch 1 and 2 is the microsteps, 3 is close loop on/off and dip switch 4 is calibration. If dip switch 4 is off i cant calibration. 1 on and 2 off is 16.microstep ( i try 1 and 2 on but is same). Do you can a calibration video with v2 board???

IF dip 4 off you cannot calibrate then your dips are not transverse. what happens if you send it a movement command does the red light turn on and the motor fail to move?
No no work normal, the red light is off. If i try move the motor with my hand, this return to last position.the close loop working. Mabe the 357.6 degress is the calibration accuracy. 360 degress -357.6 = 2.4/200 step=0.012 error accuracy
