AccelStepper library with TB6600

I’m working on a project to move a vehicle on a rail and used a NEMA 23 motor (2.2Nm torque rating) with a big easy driver. Used the accelstepper library as well.

The motor does not produce enough torque because the vehicle is 3lbs.

Need recommendations as to which 4 wire NEMA stepper to use that can provide sufficient torque. One I could use with a big easy driver.
Also if i switch to a TBB6600 can I use the accelstepper library and same code as i initially used. HELP would be much appreciated.

There are thousands of different stepper motors so I reckon you are going to have to do the research to find something suitable.

A TB6600 driver (and most specialised stepper drivers) takes the same step and direction control signals as a BigEasydriver. Just be aware that IIRC the BigEasydriver defaults to micro-stepping whereas most other drivers default to single stepping.

Oh so the issue could definitely be that I have to connect the MS pins and set them all to low.

I'm currently using 3 TB6600 drivers with the accelstepper library and don't have any issues. If your looking to buy a TB6600 driver, i'd recommend getting the TB6600-4.0 driver that has the Tobisha chip inside as compared to the standard TB6600. The standard TB6600 works good for smaller motors that handle under 2.5 amps. But the TB6600-4 driver is a lot better for medium sized motors that handle 3-4 amps. I own both versions, and one day decided to swap drivers to see how they perform and then noticed the difference between the two.

How you set the pins depends on the level of microstepping that you need.

If you don't plan to change the microstep setting with your program then just connect to MS pins to 5v or GND as appropriate.

What is the wheel radius? Divide the motor’s dynamic torque by the wheel radius to get an idea of the maximum drive you can get (dynamic torque depends on speed for steppers, its a lot less than hold-in torque,
which is what that 2.2Nm figure will be).

If you are not using microstepping, use it, or vibration/resonance effects severely limit the effective dynamic torque.

Other factors to consider are the acceleration you are using (higher acceleration requires higher torque),
and mechanical friction and gearing in the drivetrain.
