So I'm currently trying to repurpose an old 3D printer with Arduino Mega 2560 and RAMPS 1.4 shield. The 3D printer consists of 5 stepper motors and a 40W single hotend. I'm planning to use a 12V 20A power supply (S 250-12). What precautions should I take and what can be changed?
okay so its basically a Wanhao Duplicator i3 with the stepper motors, hotend and heating bed. Only parts im going to replace are the power supply and controller board, which is an arduino mega with a RAMPS 1.4 shield. The printer was originally rated to consume 240W.
