Resurrection of CubeX

thingiverse

This story revolves around the "resurrection" of an old printer known as CubeX DUO, which had sunk into obscurity in a rather unimpressive state. I received the printer in a half-disassembled condition that was less than ideal. The previous owners of this printer had certainly encountered their fair share of problems with it. My task was to get the printer up and running again, at the very least with one functional extruder. To achieve this, I opted for a common combination of MEGA2560 - RAMPS and Full Graphic Smart Controller 12864 as the foundation. The original limit switches on the X and Y axes remained unchanged - they are magnetic in nature. A mechanical three-wire limit switch was installed on the Z axis, located at the rear right corner. Additionally, I added a hot bed with a silicone heater that is powered by a solid-state relay connected to AC power. When working with the hot end radiator (a clone of direct E3D V6), it's essential to cut the thread M6. The radiator is attached to the plastic extruder body via a long hollow thermal barrier. A teflon tube measuring 2 x 4 mm was inserted through the hot-end and connected directly to the nozzle itself. The filament is fed into the printer using gear MK7, while a bearing 688 (8 x 16 x 5) presses it firmly in place. The electronic boards and power supply are located at the bottom of the printer, positioned arbitrarily. I made use of the original vents to install the electronics, ensuring they were securely fastened in their designated spots. It's crucial to lay new cables for the display and shield them properly; otherwise, there might be issues with the memory card - the printer may not detect it or fail to read from it. The archive also contains a file called MKS TFT24, which is related to the display holder. An LED strip was glued along the upper perimeter of the printer, allowing it to light up through the printer menu using the MOSFET IRF520 module. The layer height is set at 0.16 mm, with a nozzle diameter of 0.4 mm and a print speed of 50 mm/s. The material used for printing is ABS plastic, and the filling percentage is set at 100%. The display case requires about 20 percent support, while the remaining support details are already provided and will need to be removed. When assembling the extruder body, it's essential to position it 90 degrees to the left for optimal printing performance.
