did you find how many steps per rotation after you modified 28byj-48 stepper motor
@clueless3891

Didn't calculated, but If I remember correctly it was 60 step/mm and that was the setup with dvd gear mounted on 28byj-48

Hello, nice convertion. What value do you use for these small stepper motors? Same as NEMA 17 (6.60)?
@clueless3891
6 жыл бұрын
Alex Echeverría Thanks. No, try about 3.50. If they get hot, reduce more. Motor load play a huge role in calibration. Warm is temp that we want.

Thanks! I wonder if you can tell me if I can use the A4988 controller for "Step-Syn" stepper motors, that run at 3V - 3A . They are big and I happen to have four of them from a used machine.

Alex Echeverría Hmmm, I am not sure. I wouldn't use A4988. Better solution would be TB6600 with some controller board and mach3 software. Sorry but i dont have that much experience with stronger stepper motors.

Hello, I have done this convert, only the motor is not strong enough for my project. Is the Nema 17 much stronger torque than the 28byj-48? If I google it looks the same but nema is alot bigger, should be stronger?

Hi, I modified a 28BYJ-48 to bipolar as You have shown in this Video but now i connected the motor to an CNC shield and its just making a sharp sound and its not moving Do You have an idea what i've had done wrong? Please Help, thanks

1. Check wiring 2. Adjust current on stepper motor driver 3. Reduce steps/mm to 60

Try to google model number but I think that if you connect this to a standard bipolar driver, you will not use the yellow or white wires that are at the midpoint of each coil if they exist on the motor that you received. The black wire connects to A+, the green wire connects to A-, the red wire connects to B+ and the blue wire connects to B-. buildyourcnc.com/Item/electronicsAndMotors-nema17-62ozin-NEWBIEHACK-motors-stepping_motor-62_ozin

This is how to adjust the current, just find the best value for your setup, if stepper motors get hot they will lose steps kzitem.info/news/bejne/26OQy6KZcmlnaXo
