3D Systems CubeX to RepRap Conversion

April 11, 2020


The controller has been replaced with an Arduino Mega 2560 outfitted with a RAMPS 1.4 board and the screen has been replaced with a RepRapDiscount Full Graphic Smart Controller. The stepper motors are all still original.




The stock extruder has been replaced with the much more trouble free E3D V6 Hotend.


Build Platform

I have replaced the included glass build platform with a heated bed covered with an adhesive PEI sheet. The heated bed consists of a 12 x 12 " 1/4 " thick milled aluminum plate with a flexible silicon heater underneath controlled by a solid state relay with the standard E3D Cartridge Thermistor.

The firmware is Marlin 2.0 set up for the new extruder, heated bed, and calibrated for the stepper motors.

The M92 Calibrated Step Settings are: X87.53 Y87.42 Z1084.79 E80.12

Currently I have disabled the display as it was acting strange powering off / preventing the controller from powering on.
