Hello, I am about to begin scratch building another 3D printer. All the materials have been delivered, and I have been working on testing the RAMPS electronics. I have successfully compiled and uploaded the motor test code, and the lights are flashing but there is no movement, sound, vibrations etc. coming from the motors. Any help would be appreciated. Thanks! https://reprap.org/forum/read.php?219,448962,448962#msg-448962 Mon, 20 Jul 2026 21:50:21 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?219,448962,449559#msg-449559 https://reprap.org/forum/read.php?219,448962,449559#msg-449559 spaceorange12 RAMPS Electronics Wed, 31 Dec 2014 18:14:34 -0500 https://reprap.org/forum/read.php?219,448962,449284#msg-449284 https://reprap.org/forum/read.php?219,448962,449284#msg-449284

All the jumpers should be in place under drivers
the pots on drivers come preset

Following image shows 4 driver installed correctlyon RAMPS

If you put them in the wrong way -- they probably are fried!

DO NOT diddle, wire or un-wire with power ON
turn OFF motor power supply and disconnect usb before wiring changes

Is it wired correctly

Blinking LEDs show heater circuits D8, 9, 10 working

Check colors on motors to make stepper phases correct 1A 1B 2A 2B
