Hi
I have to connect my tb6600 driver over a level shifter to mks Sbase 1.3.
I have tried the following setup:
mks sbase 1.3 level-shifter TB6600
P0.4 ----------> B4 A4 --------> PUL+
P2.0 ----------> B3 A3 --------> DIR+
P2.1 ----------> B2 A2 --------> ENA+
GND ----------> GND
3.3v ----------> 3.3V
5V ------------------> 5V
GND ------------------> GND ----> PUL-,DIR-,ENA-
B+ --> Stepper
B- --> Stepper
A+ --> Stepper
A- --> Stepper
VCC <---------- Power Supply Stepper
GND <---------- Power Supply Stepper
I use the following level shifter:

Problem:
1. If i checked the output via A4 saw the signal via a 5v Peak
2. As soon i connect my TB6600 on the line an i messure the voltage on the TB6600 PUL+ to GND is see only 2.2v
3. the stepper is not moving
Setup:
1. 3.3V and 5 Volt is comming from the board
2. VCC and GND for Stepper is comming from another Power Supply
3. Board or Pins are not configured as open train.
Does somebody has any idea what went wrong?
Or does anyone have experience with level shifter and TB6600?
