recently i'm thinking about using L293D h-bridge with current sensing for stepper driving the specs for L293, L293D are here l293.pdf 390.55 KB and the pinouts are as follows 1 1,2EN | VCC1 16 2 1A | 4A 15 3 1Y | 4Y 14 4 GND | GND 13 5 GND…

I have to wonder why all those 3D printers and CNC machines use the A4988 and DRV8825 drivers given all of their disadvantages.
