MaybeCube Assembly Instructions

These are the assembly instructions for the MaybeCube. These instructions are not fully comprehensive, that is they do not show every small detail of the construction and in particular they do not show the wiring. However there is sufficient detail that someone with a good understanding of 3D printers can build the MaybeCube.

Read this before you order parts

Extrusion: 2020, 2040 etc aluminium comes in variants with differing sized center holes - some are suitable for tapping for an an M5 bolt and some are suitable for tapping for an M6 bolt. It doesn't really matter which you use, but ensure you buy the bolts that correspond to your extrusion size. These build instructions assume M5 bolts, if your extrusion requires M6 bolts then the 10mm and 12mm buttonhead M5 bolts should be replaced with M6 bolts.

Z-motor and leadscrew: The motor for the Z-axis has an integrated lead screw: in the Parts List the length specified is the length that protrudes from the motor. Some suppliers specify the total length of the lead screw, that is including the part that is inside the motor, so check how your supplier specifies the part before ordering. Another option is to order a motor with a lead screw that is too long and cut to size, note however that lead screws are made from hardened steel and cannot be cut with a hacksaw - an angle grinder is required to cut them.

Build plate: For the MC350 variant I have specified a Voron Trident build plate (this is an 250x250mm aluminium tooling plate drilled for a 3-point fixing) and a silicone heating pad. A cheapr alternative would be an Ender-style 235x235mm print bed with 4 fixing bolts.

Sliding T-nuts and hammer nuts: Sliding T-nuts and hammer nuts are somewhat interchangeable. I find T-nuts easier to use: sometimes it can be to get a hammer nut to "bite". Hammer nuts allow more flexibility: they can always be added or removed without disassembling the frame. Genenerally hammer nuts can be replaced with sliding T-nuts, as long as it is done early enough in the assembly. Sliding T-nuts can always be replaced with hammer nuts.

Washers/shims: Standard M4 washers are 1mm thick. Where "M4 x 9mm x 0.5mm" washers are specified, these may be ordered as "M4 shims".

Side and back panels, base, and base cover: These are specified as "CNC routed parts" in the parts list, for the convenience of those with access to a CNC. CNC routing is not required, the only "machining" required is to drill holes for attachment to the frame, which can easily be done with a hand drill.

This is a full build, some parts can be omitted to save cost, in particular:

• the Big Tree Tech relay module, if you don't want auto shut off
• I've specified a Big Tree Tech mainboard, you of course can use any mainboard you like
• the polycarbonate side and back panels, if you don't want to enclose your print volume for (say) printing ABS. Note that these panels also add rigidity to the printer.

Printing the parts

A number of parts are in proximity with heat sources, namely the hotend, the heated bed and the motors. Ideally these should be printed in ABS, but I have used PETG successfully.

The STL files for the parts are in the recommended orientation for printing.

Parts are designed so that vertical features are aligned on a 0.5mm grid, so parts should be printed with either a 0.25mm or a 0.5mm layer height. For speed of printing most parts can be printed with a 0.6mm nozzle with a 1.0mm layer width and a 0.5mm layer height. Some parts, however, require a finer resolution and should be printed with a 0.25mm layer height namely: *All parts of the X_Carriages (ie anything prefixed X_Carriage_) *All parts of the Y_Carriages (ie anything prefixed Y_Carriage_) *The XY_Motor_Mount_Pulley_Spacers *The Smart_Orbiter_V3_Duct and the Smart_Orbiter_V3_Fan_Bracket

Right_Side_Upper_Extrusion assembly

Vitamins

Qty	Description
7	Bolt M3 caphead x 8mm
4	Bolt M5 buttonhead x 12mm
1	Extrusion E2040 x 350mm
1	Linear rail MGN12 x 350mm
1	Linear rail carriage MGN12H
7	Nut M3 sliding T

Assembly instructions

1. Bolt the MGN linear rail to the extrusion, using the Rail_Centering_Jig to align the rail. Do not fully tighten the bolts at this stage - they will be fully tightened when the rail is racked at a later stage.
2. Bolt the Y_Carriage_Right_assembly to the MGN carriage.
3. Screw the bolts into ends of the extrusion in preparation for attachment to the rest of the top face.
4. Note that the last two holes of the rail are not used - the Y_Carriage cannot travel here since the motors are in the way. Not using these holes shortens the constrained length of rail and so reduces the flex of the Y axes caused by bimetalic expansion when the frame heats up during printing.
