Active Posts. This requires. If this a3977 stepper is sized to provide a lot of torque for cutting, then when doing high speed moves, the motor can be driven faster, into the region where the torque decreases. This a3977 stepper in practice might be suitable for IPM high speed moves without losing steps.

Say thanks and help MakerBot continue to share amazing Things with the Thingiverse community. Or it will just fry it all over. Btw, tyvm for all the info in a3977 stepper blogs.

Stepper Information

The A will supply an absolute maximum of 2. Without a heatsink the maximum is somewhere between 1.


You can't increase that by adding transistors. Wish List. Show Ignored Content.

A3977 stepper other two on the other two controller outputs. Don't know what else to do. If the two leds on the left are across one coil and the two on right are across the other coil that should turn the motor. Damm this is embarrassing, as a act of desperation I connected a different driver, the one Darryl helped me with last year, and it didn't work!! Finally I checked the coil resistance and found it open then checked the other wires and found the low resistance expected, tada it works!! Step angle is 1. When operating in full stepping mode.

Now customize the name of a clipboard to store your clips. Arduino, A, and AD Be carefull here. For a3977 stepper shipping cost ,we will contact each other according to the items Contact informations : E-tansense Technology co.

Audible noise in Stepper driver A3977

A3977 stepper help will be appreciated heartly. Each of the trimpots on the bottom of the board have a a3977 stepper test pad directly below them. Additionally, there is a large, GND test pad on the right side that is connected to ground.


Is it possible with A to keep only one phase ON in standstill position"? The A uses a3977 stepper Sleep input to minimize power consumption when not in use.

This disables much of the internal circuitry, including the output DMOS, regulator, a3977 stepper charge pump. One option of particular interest is the stepping mode configuration.
