MPCNC All-In-One-Box

thingiverse

Since the overly complicated power supply unit box was far too intricate for a relatively modest return on investment, I decided to revert back to analog speed control but consolidated everything into one compact enclosure, including the controller. The wiring has become significantly simpler with the power flowing through the emergency stop button and the non-isolated spindle wires separated from the controller board in a manner that mirrors industry best practices for safely isolating high and low voltage lines. Initially, I intended to utilize a standard RAMPS 1.4 board with its larger display screen directly, but ultimately opted to incorporate B-Cup's design instead, despite my initial reservations about its aesthetic compatibility with my rugged enclosure design. I did drill an additional hole to accommodate a fan and subsequently mounted a vent fan after completing the print job; however, I'm unsure whether this was truly necessary given that my motor drives don't draw excessively high currents, thereby precluding excessive heat buildup.
