Oumefar RAMPS 1.4 Controller, MEGA2560 R3 Board, 5pcs Soldered A4988 Stepper Motor Drivers + 5pcs Heat Sinks + 19pcs Jumpers with USB Cable for RepRap 3D Printer Kit

Needed to replace some printer parts. Works like it should.

I purchased this for a 3D printing project, but unfortunately, I had a disappointing experience. Despite careful assembly and troubleshooting, the board failed to drive my stepper motor, a task it’s explicitly designed to perform. I tested the same motor with another setup (Arduino Uno and a CNC shield), and it functioned correctly.Moreover, it’s not just about the faulty product, but the significant amount of time and energy spent trying to get it to work. As someone working on a project schedule, these delays have been frustrating.

thankfully I had a couple of Mega 2560s in my stash. These were several years old. The new one would power on via the USB, but never showed up in the device manager. The two older versions connected just fine and I was able to program them. And my wife always critizises me for keeping "all this junk". See???

Full kit of RAMPS controller base board, plus the stepper drive plug-in baby-boards, plus the MEGA Arduino compatible micro-controller module is already for experiments with up to a 3-axis positioner and the power control for heated extruder operation.
