|RepRap Motherboard v1.2||59.00||1||Makerbot||1|
|Extruder Controller v2.2||50.00||1||Makerbot/ebay||1||
Currently out of stock.
Found it on ebay for $48
|Stepper Motor Drivers v2.3||35.00||3||Makerbot||1||Includes cables. This was set at 3 but do we need another for the extruder? The extruder control board will handle the motor control as well as the heater.|
Having trouble finding distributors for non-kits.
Update: doesnt matter, included in the reprap motherboard
Do we need a Arduino variant if we get the Makerbot Rep Rap motherboard?The *uino's all use the same code, but there I/O pins, speed and other specs are different. Mega is the best at the moment so I think we should be ok.
Correction, motherboard has built in sanguino.
|Opto Endstop v2.1||5.00||6||Makerbot||1||2 for each axis (Home & End) More Info: reprap.org/wiki/OptoEndstop_2.1|
|ATX Power Supply||35.00||1||1|
|Stepper Motors||24.00||4||Makerbot||1||Nema 17 13.7 N-cm (that is 1400 g-cm or 19.4 oz-in) 3Axis + Extruder. More Info: reprap.org/wiki/StepperMotor|
|precision acme threaded rod||mcmaster,donated?||1-for each axis. length?|
|threaded rod nuts||mcmaster|
|rod pillow block||6||mcmaster/fabricate||support both sides of threaded rods|
|shaft coupling||3||mcmaster/fabricate||1for each rod to motor assembly|
|linear motin( bearings/guide rails/etc..)||3||80/20,mcmaster, etc||quantity in respect ro assembly|
|Nichrome wire||10.00||1||Various Sources||Optionally www.makergear.com/products/ceramic-heater-core|
|Barrel||1||Fabricate||Material Cost Only which is minimal|
|Insulator||1||Fabricate||Material Cost Only which is minimal (Use Peek)|
|Extruder (Geared Printed parts)||40.00||1||Ebay/Other||We could probably fabricate|
|Highly dependent on design (Entering a rough estimate)||150.00||1||Various||A lot of fabrication cost for materials and components. Need further breakdown once design is stable.|
|motor mounts||3||fabricate, laser cut||how the stepper motors will attach to the frame|
|tool attachment mount||1||fabricate,laster cut||initially this is the mount for securing the extruder to the z-axis, however we need to make it flexible enough and come up with a standard on how tools will be interchanged whether to cut, extrude, etc...|
|ABS(Natural)||45.00||1||Makerbot 5Lb reel||Smaller Reels Avail as well.|
Materials (old design but electronics are still valid)
