Please, can you explain this? Your smoothie is running 3.3v logic the driver most likely needs 5 so you need a logic gate or set the pins to ground and connect a 5v PSU to the PUL+ DIR+ and STEP+ i had the same problem with the radds on due which is also a 3.3v logic. I solved that problem using logic level shifters hope this helps. I have the same problem. I Want to drive RADDS with 2M542 bby jaumebel - Smoothie
Yes. it's solved. It was a bad wiring. Dir - / Step - / Ena - Are common Ground. Dir + / Step + / Ena + Receive signals form arduino. Everything is going right. Thank you for your responses. Jaume Belby jaumebel - General
I'm building very large 3DPrinter (600x600x600) with Arduino Mega and 2M542 Drivers combined , with two motors NEMA 17 on X axis, two on Y, and 4 motors on Z axis. Everything is going right but only in one direction, drivers doesn't change direction of steppers. I've tryed some drivers 2n542, swap x, y and z positions, check wirings and the problem still persists. Arduino works perfectly if Iby jaumebel - General
