McWireCartesianBot 1 0

McWire Cartesian Bot v1.0

The design for this cartesian bot is inspired and heavily based on the initial design by Tom McGuire. He created an easy to assemble, easy to fabricate, and easy to work with cartesian robot that is suitable for integration with the RepRap project. On these pages, we will be documenting and elaborating on his initial work, as well as providing additional enhancements. It is a work in progress, and this page will be updated frequently.

Project Status

All work is being done in the trunk/users/hoeken/mcwire-cartesian-bot/ of the RepRap subversion repository.

CAD Drawings

TODO

• Add mounting holes to vertical base for flange.
• Create Dremel Attachment Mount Plate.
• Create Thermoplast Extruder Mount Plate.
• Create X and Y motor mount drawings.

DONE

• Create initial DXF drawings of parts
• Create Base drawing.
• Create X stage drawing.
• Create Y stage drawing.
• Create Vertical Base drawing.
• Create Z Axis drawing.
• Create Bearing arm drawing.
• Create Z motor mount drawing.
• Resize X/Y/Z components to be printable on both US Letter (8.5" x 11") as well as A4 (8.3" x 11.7")
• Resize base to accomodate Y stepper motor.
• Add mounting points for minimum/home endstops
• Create "Mount Plate" interface... essentially 4 set points to use for mounting a 'plate' which can contains whatever type of toolhead you want.
• Redo z motor mount to have mounting holes on both sides. move drive over 20mm, re-layout bearing, etc.
• Fix screw placement on Z rails
• Add extra nail holes to z carriage

Construction

• Determine if component specifications work: #10-24 x 3/4" screws, 3/4" x 3/4" rails, 1/4" acrylic, etc.
• Solicit feedback from RepRap community.
• Mockup design with cardboard and printouts.
• Order test run of laser cut parts.
• Assemble test run and document assembly process.
• Release files on sourceforge: DXFs as well as pre-made PDFs to print for hand-made machines.
• Order laser cut kits for the community.
