now the info for rework, I hope you have experience in electronics and mechanics.
Arduino mega 2560
5 stepperdriver: drv8825 or 4988 or tmc2100
Powersupply 12V 14A
Powersupply 24V 14A
SSR input 3-32V 25A relais
Build Tak 3D print surface
Cable and connectors, tools and alot of time.
1.step: find which cable is which steppermotor.
Extend this cable to the ramps1.4 , use connectors, don´t cut the original cables.
You need red, blue, green and black cable.
2.step: the hotend use 24V, the ramps1.4 supply only 12V. in this case you need 2 powersupplies and solid state relais (SSR) input 3-32V 25A.
Route separate cable for heatcarriage and thermistator of the hotends and connect it to ramps.
3. step: extend endstop cable as well and connect it to ramps.
4. step: heatbed MK3 with build tak, the MK3 is fixed with doublesided tape on the printbed.
You can use 24V with ssr relais, connect it to ramps, don´t forget the thermistator.
5.step: download marlin and arduino software, do the configuration.
I have no pictures, the printer is working verywell, we use Simplify3d, no coding here - no coding there, only printing with PLA and ABS
