Stepper motor

Hey Rob,

I want to connect a stepper motor that runs at a constant speed continuously.

I am guessing this could be done outside the robo app.

I can see you can do this via the db9 connector.

This may be a very simple question but, how to run a code outside the robo app?

How would you connect the pins to the db9 output? Do you need a seperate stepper motor driver?

Thanks,

Dilshan

Hi Dilshan, yeah at this time you would need to run a separate script to control the stepper motor and you would need a stepper motor driver. If you search around for "Connect stepper motor to Raspberry Pi tutorial" you'll find various tutorials. Once you have it running you would create a "service" on the raspberry pi which will keep the stepper script running in the background. Here's a few links on different techniques and drivers, at this time I'm not really sure which is the best, maybe the first link.

Raspberry Pi Stepper Motor Control with NEMA 17 — Maker Portal

The NEMA 17 is a widely used class of stepper motor used in 3D printers, CNC machines, linear actuators, and other precision engineering applications where accuracy and stability are essential. The NEMA-17HS4023 is introduced here, which is a version of the NEMA 17 that has dimensions 42mm x 42m

Raspberry Pi, Python, and a TB6600 Stepper Motor Driver

Raspberry Pi, Python, and a TB6600 Stepper Motor Driver: This Instructable follows the steps I took to connect a Raspberry Pi 3b to a TB6600 Stepper Motor Controller, a 24 VDC Power Supply, and a 6 wire Stepper motor. I'm probably like many of you and happen to have a "grab bag" of left-over...

Here's the pinout's for the DB9's on the main controller, these are GPIO's untouched from the Pi, in the tutorials when they show connections to the Pi GPIO's this is the same.

Here's a DB9 breakout that makes it easier to work with the DB9's.


Let me know how it goes.
