I am begginer of 3-D printers and i have built Prusa Mendel Iteration 2. With very big hope, i tried to work it but the result is nothing. My arduino connects the my computer. It gets all signal from my computer but it doesn’t direct signal to motors, heatbed, and extruder. I am using 20A 480W power supply. My stepper motor is working in 1.7A (model no is 4401). So, according to you, where the problem is? I get crazy for days just because of this problem…
First off I would seriously recommend marlin over sprinter but it does sound like you have some configuring to do Send me a pm I can maybe setup a Skype call and walk you though it
This may be an obvious thing to those more familiar with these, but 20A at 480 W comes to 24V, not 12V. Just curious. As others said, I’d check for power at the board inputs.
Are you sure your endstops all are connected correctly. If you plug them in the wrong way or wire the wrongly the short out and nothing works any more.
Sencond question do you have a screen connected to your printer?
