Projects/MendelMax: Difference between revisions

Revision as of 11:18, 3 September 2017

Discussions about the Workshop/3D_Printer for the space resulted in the conclusion that for maximum durability we should build a Mendel Max.

Please consult with Martyn before ordering/purchasing any parts.

The Space MendelMax currently requires :

Possibly some more LM8UU bearings
An enclosure for printing ABS
Glass Bed to replace mirror ((for better heat distribution)James R is looking into cutting and shaping some)

Structure
- ~~Plastic parts~~
- ~~T-Slot aluminium~~
- ~~Nuts and bolts for above~~
- ~~8mm smooth rod 4*550mm (X&Y axis) 2*460mm (Z axis) TBA~~

(Confirm with Martyn before ordering)

Mechanical
- ~~LM8UU bearings~~
- 5*NEMA 17 bipolar/hybrid stepper motors (Torque >=13.7 N-cm/1400 g-cm/19.4 oz-in, 5mm shaft).

 The Space MendelMax currently requires :
-* Motors - 5 needed for single extrusion, 6 if we go fancy dual extrusion - [http://www.emakershop.com/browse/motors eMakershop a possibility]
-* Smooth Rods - Metal Supermarket, all 8mm we have decided
-* Electronics - SmoothieBoard or 4Pi arm-based electronics are ideal, but mostly only about to be released
-* Timing Belts - Need to look up the specs.
-* Extruder/Hot End - Martyn has a spare heated nozzle ready, we need a ceramic spacer.
-* Heated bed* - Maryn has got a slightly iffy quote from china (direct import) for $45 each for 2 with $40 delivery.  Alternatively part no. SRFG-1212/5-P-230V from http://omega.co.uk
 * Possibly some more LM8UU bearings
+* An enclosure for printing ABS
-(*)A heated bed is not strictly necessary for PLA but makes it a lot more reliable, and essential for ABS
+* Glass Bed to replace mirror ((for better heat distribution)James R is looking into cutting and shaping some)
