P3Steel Build Log (#13) – Print Bed Silicone Dampeners

By ChunkySteveo,

To support the print bed from the y-axis and the bed frame Prusa 3D printers use bolts, washers and nuts on each corner with a spring for tension. Toolson’s edition of the P3Steel does away with these springs and opts for a novel (genius) solution of using silicone dampeners.

P3Steel Build Log (#12) – RAMPS and Arduino Mega (aka The Brain!)

By ChunkySteveo,

For this printer I will be using the standard and simple setup of an Arduino Mega and a RAMPS 1.4 board. The Arduino Mega is the brains of the printer and will process all the g-code instructions from the .gcode files from either an SD card or over USB and tell the printer how to move, heat up, extrude filament etc by signalling all the motors, heaters and sensors on the printer which are connected via the RAMPS board, which in turn is connected to the Arduino Mega via the GPIO pins.
