This is my ridiculously over engineered previously working (but not for a while) Prusa i3 3D printer…
Currently in disrepair (bed assembly needs to be put back together) and everything needs to be setup again.
Consider it a project so you should be comfortable taking on building a 3D printer build if interested…
Consists of:
- 12V 30A Power Supply (with attached power switch and cord socket)
- RUMBA driver board (with 5x A4998 drivers) with cooling fan
- LCD Screen Controller with USB and SD Card sockets
- 5 NEMA 23 stepper motors (42BYGHW804)
- MK2a-ALU Heated Aluminum Bed
- BlinkM LED Driver (can connect to driver board via I2C, supported by Merlin)
- RGB LED Strip Across top (to be driven by BlinkM board)
- Hot End (can’t remember what version)
All mounted on a 3/4" plywood base with handles
Frame has been strengthened with bits aluminum angle stock
Comes with the parts to put it together and:
- 3x spare RUMBA board (not sure if any of the 3 actually work)
- Spare extruder parts
- Spare drivers and wrenches
- Power cord
- 3D Printing Book (has good information on Prusa i3)
- Possible Borosilicate Plate (I had one but can’t seem to find it)
Here are a few test prints from when it was working…
Issues:
Needs USB to USB mini adapter to connect the extended USB cable to the RUMBA board (I had one but can’t find it)
I went overboard with the wiring and cable management (you could simplify it)
The extruder has always given me issues (filament slips and it’s too big so moves slowly)
I used end stop switches on both sides of each access (you only need 1 side)
Its’ heavy
Price: Hard to price as costs of printers has come down compared to when I started this (@SteveRoy @KevMacD helped me tremendously) . I based my price on the value of the stepper motors and power supply (the value to me anyways) as I can use those on other projects…
