Fisher build instructions

Overview

The Fisher Delta 3D printer is a faster to assemble, networked 3D printer with bed probe for full geometric compensation.These pages are the complete instructions for building, commissioning and using the Fisher Delta 3D printer. Like all RepRap machines, it is fully open-source, licensed under the GPL. All the design files and software are available from the eMAKER Github repository.

The Fisher Delta 3D printer is fitted with the open-source Duet electronics.

If you want to print the plastic parts for a Fisher Delta 3D printer, see below.

General notes

  • BEFORE YOU ATTEMPT TO ASSEMBLE ANY PART OF THE FISHER DELTA 3D PRINTER, PLEASE READ THESE BUILD INSTRUCTIONS FULLY AND ENSURE YOU UNDERSTAND THEM. Although all parts are covered by warranty, this will be invalidated by your not following these build instructions. You are building a complicated machine; many different skills are required to build, to commission and to operate a 3D printer. Try not to rush your build, or you may miss out something vital!
  • Give yourself plenty of space and ensure your work area is clean. Dust and dirt are a 3D printer’s worst enemy.
  • All printed parts have been printed on RepRap machines. Despite the fact that these machines are highly tuned RepRap 3D printers, some holes and features may need a little fettling to get the best performance from the Fisher Delta 3D printer. There is a video how-to on fettling 3D printed parts here on Vimeo.
  • Before you start the build, please ensure you have all the components as listed on the packing list included in the kit. If anything is missing or damaged, please contact us.
  • We understand that people may want to change aspects of the machine’s design, and in fact we encourage this as it is one of the benefits of open-source development. Before changing anything, please be aware that the Fisher Delta 3D printer has been designed to maximise its build volume relative to the the machine’s footprint, and as such many of its components fit closely to others. So consider your changes carefully before you try to implement them. And when you find improvements, please tell us and the world so that we can include them in future kits, and so that existing owners can upgrade their own machines.
  • The Fisher Delta 3D printer is a robust RepRap machine once assembled; however it does require a certain amount of care during assembly. If in doubt, force is usually not the answer! There are many ways to get support and advice; see below.

Printing parts for Fisher

If you have bought the hardware-only version of the Fisher kit, you will want to print and/or laser cut the parts. You may also want to print/cut spare parts for your printer. Parts are available as STL and DXF files (as appropriate) and SolidWorks files. You can also view a whole assembly of the printer, using the SolidWorks assembly file, in the free SolidWorks eDrawing viewer program.

The latest versions of parts (which should generally be backwards compatible with previous versions of Fisher) are available in the Fisher github repository. The geared extruder drive is in it’s own geared-extruder-drive github repository.

You can download the whole github repository, or download the parts individually. The list below shows the part number, part name, quantity and location of the parts. The ‘Location’ links to the parts page. This will also help you identify the parts, as it shows a preview of the part (STL only). If you download the parts individually, make sure you download the ‘RAW’ version of the file; if you right-click on a link and download, you will end up with a file with the right name (with .stl on the end), but it will actually be an html document!

STL parts (for printing) are in the Fisher/stl folder.
