How to wire 4 stepper drivers TMC2209 using UART and a A4988 to a mcu - diy 3d printer board

Показать описание
I explain my diy 3d printer board on how to connect the stepper drivers.
Connect 4 TMC2209 using UART to ESP32, arduino or any microcontroller.

TMC2209
The slave address SLAVEADDR is selected by MS1 (bit 0) and MS2 (bit 1) in the range 0 to 3 - so you can have 4 drives for X,Y,Z and E0
MS1: 0 MS2: 0 - Slave Address 0
MS1: 1 MS2: 0 - Slave Address 1
MS1: 0 MS2: 1 - Slave Address 2
MS1: 1 MS2: 1 - Slave Address 3

NOTES:
- RX and TX shown in video are from the microcontroller. The RX pin goes to RX pin on microntroller
- if you get the TMC2209 with the yellow header, note that the UART pin it is the 5th by default, as pin 4 and 5 are not conected togheter as with other modules.

Cel mai bun video de pe net care explica cum se setează adresa in UART mode pentru MS1_AD0 si MS2_AD1! Mi-as fi dorit sa fi venit din prima aici ca documentația de la producător nu prea e clara. Mulțumesc și apreciez prezentarea care este foarte bine făcuta!

Wow, this is amazing, I wish I found your channel sooner. This is amazing, a truly diy 3D printer. If I may ask, what is the max. build volume and how much did the complete project cost?
