This article is the extended version of a material list for the RepRap Morgan. By Robert Kuhlmann.

Thanks to Quentin Harley for his permission and for his outstanding RepRap Morgan-project.

Introduction

I've decided to start this page not only to show my Morgan-project, but to enable a seperate development branch of Quentin Harleys outstanding work and to post my ideas without intervening with Quentin's work. I would be honored, of course, if some of the ideas that may evolve over here, finally make it into Quentin's project.

On the other hand I'll try to keep this project up to date with Quentin's progresses and ideas to make this a very progressive and attractive Morgan-project.

This side is still under construction, but I've decided to give it to the public now, because some files and ideas may already be of interest for the community.

You may use all the files and ideas for free and with no restrictions, except of claiming they were your own work. If you want to derive your own Morgan-project from here, feel free to do so, but please let this project go its own path. You can, of course, discuss any aspect on the discussion page here and I'd be very happy and thankful for comments, critics and recommendations.

The parts published here are used in my own RepRap Morgan project. My virtual Morgan has a real brother in a similar state. The virtual Morgan is used as proof for the measurements of the parts in this BOM. While building the virtual Morgan, many corrections on the parts have been done already. If you find mismatches or faults, please let me know, so I can update this BOM and keep it in the best possible state.

News

This section will give some brief information about the last changes.

  • Update 08/20/2013:
News-section established.
Regarding to an idea in Quentin Harleys forum (Morgan Builders Forum) I designed a new version of the bed-z-mount-bracket to fit with the "Threadless Ball Screw"-project from Mark Sollack (Thingiverse Thing 112718). It raises the vitamin count for the morgan a bit, but you don't need any threaded rod oder trapezoid rod, no anti backlash spring and no z-axis-nuts any more, just 3 small bearings (size 624 or 623), some nuts and screws and one printed part.
I love that thing, because its as charming as the Morgan itself.

Printed parts

You find the original SCAD-file from Quentin Harley, that does all his original parts, over here: Original Morgan SCAD-file

I've redrawn all printed parts to ease modifications for me, because I'm working with Autodesc Inventor.

ZIP-Archives with all files can be downloaded here: All drawings All Inventor files All STL-files

Hardware

I'm using steel- instead of brass- or copper-pipes for the vertical PSI- and Theta-axis, because I can get them in a very slim variant, making them more lightweight, while being more stable and even less expensive, compared to their copper pendants.

<todo> 2mm self tapping coach screws, 40mm

hard spring (idler compression) 7mm

cabinet coach screws, 5mm </todo>

PCB heated bed

I've uploaded my own design of a heated bed here. The archive contains the assembly group and the discrete parts. You need to create an idw-file from "pcb heated bed copper.ipt" to get the layout.

Two tips for that: 1. You should set the line-thickness of the drawing to 0.01mm, color white. If you want a lower resistance with the same layout, just set the line-color back to black. The hole-marks of the PCB fit with the OpenHW-plate as well as with my own here in the BOM.

The building platform can be fine adjusted with three screws. The usage of more screws for adjustment is optional (not recommended though).

To be done
