I came across this little stepper controller board that does just what I needed. This can manage the motor's position, auto home, and more. This is a quick overview, as I am already using this board in a larger machine that's nearly finished.

Thanks for the vid and comfort and health to your friend under the bench. I've got a couple of Cardigans and I couldn't live without my nitwits.

It seems that the PID algorithm is pretty good for acceleration/deceleration ... thanks for the heads up on the unit ... seems cost effective.

Man that acceleration is so sexy

How do you find the stepper noise, is it almost silent like a Trinamic TMC2100 stepper driver (but smarter?)

There is some but it’s pretty quite

Have you looked into the tmc 2209?

Can someone explain what are the two chips on the breadboard? (Not the tic) And am I able to do what is done here without the two chips?

On the breadboard, the chip on the left is a rectifier that isn't used. The small board in the middle is a level-shifter like www.amazon.com/Adafruit-4-Channel-I2C-Safe-Bi-Directional-Converter/dp/B00NAY3J7O or www.amazon.com/HiLetgo-Channels-Converter-Bi-Directional-3-3V-5V/dp/B07F7W91LC The level-shifter is not required, but some devices won't detect the i2c communications at only 3.3V levels. In the final machine I used a USB-TTL adapter to communicate with the Tic using the serial protocol.

@@Corgitronics may I ask why the usb ttl adapter. Was the software not working properly? Or were you developing some type of script

@@neneeveryday2716 The machine I made used all of the available pins on a Raspberry Pi 3 for sensors and input buttons, so I had to move the stepper controller to a USB connection.
