Tool Changing 3D printer with a larger print volume and minimal machined parts.

The design is pretty much completed and I am currently ordering and printing components. I plan to have it built within the next couple of months or so.

• Use the duet 3 board plus appropriate expansion boards
• Have direct drive tools
• Use a motor on the carriage for the tool changer (although this may be upgraded down the line to cable driven)
• Have 3 point levelling
• Have a minimal number of machined components (at the moment this stands at the bed and the locking pin).
• Design everything in Solidworks
• Stay E3D Tool compatible (my tools use 10mm balls but this wouldn't affect the tool changer)

These aren't in any particular order

• Design an exnclosure
• Add a method of wiping each tool
• Swap to the E3D Hermes when available
• Release duet config files
• Sort out electronics layout
• Update the bed model to include embedded magnets for swappable print surfaces
• Determine location of end stops for X, Y and Z

The design will be supplied in the following file formats

• Solidworks - All files in native 2019 format. This is what I use to model everything
• Step - All files will be available as step. The assembly step files are segregated.
• STL - All printables
• 3MF - All printables
• PDF - Drawings for all machined parts

I welcome any feedback on this printer and will be working more on the design over the coming weeks.

I'm a mechaical engineer by trade and have been dabbling in 3D printing for the last 9 years. I have owned a number of printers, mainly cartesian or delta types. This is my first coreXY. I plan on posting on My Blog with my build progression. There is a Discord Server. Come and join me for a chat!
