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!
