This story is about the "resurrection" of the old man CubeX DUO, who has sunk into oblivion ingloriously.
He came to me in a deplorable half-disassembled state.
The printer brought a lot of trouble to their previous owners.
My task was to restore the printer to working condition, at least with one extruder.
The basis was taken common pair MEGA2560 - RAMPS and Full Graphic Smart Controller 12864.
The limit switches of the X and Y axes remain original - magnetic.
A mechanical three-wire limit switch is installed on the Z axis, at the rear right.
Added a hot bed with a silicone heater that is turned on by a solid-state relay to AC power.
In the hot end radiator (clone direct E3D V6) you need to cut the thread M6.
The radiator is connected to the plastic extruder body by means of a long hollow thermal barrier.
A teflon tube of 2 x 4 mm was laid through the hot-end to the nozzle itself.
The filament is fed with gear MK7 and pressed against it with a bearing 688 (8 x 16 x 5).
Electronic boards and power supply are arbitrarily located in the bottom of the printer.
I used the original vents to install the electronics in their place.
It will be necessary to lay new cables to the display and ALWAYS shield them. Otherwise, there will be problems with the memory card - the printer will not see it or will not be able to read it.
The archive also contains the display holder file MKS TFT24.
An LED strip is glued along the upper perimeter, light up from the printer menu via the MOSFET IRF520 module.
The height of the layer is 0.16 mm.
The nozzle is 0.4 mm.
The print speed is 50 mm / s.
Plastic - ABS.
Filling - 100%.
The display case requires support of about 20 percent, the remaining support details are provided and will need to be removed.
The body of the extruder for printing should be put to the left by 90 degrees.
