2015 I started a tool changer project and have been silent about it way too long. Since then, I had sooo many other projects going on and didn't focus on this like I should have. For now, I want to share some of my progress videos I did last year. End of 2016 I designed a new printer around the tool changer with even the last little screw needed, to fit the tool changer better and called it 'weP' (for well-engineered Printer). Up until now, I never found the time to publish this like it deserves it and I probably won't have the time for it long time from now on.
This printer runs on a Cohesion3D Remix, capable of 3 independent printheads. Direkt or bowden, different hotends, nozzle sizes or materials, it can do it all simultaneously. Smoothieware and S3D are needed with S3Ds scripting capabilities to make the tool change independent from the print itself. I can tell, that switching to Smoothieware made my testing and prototyping way easier then the RADDS/Due I had before.
Hotends are my own design with E3D-V6 heatsinks. They do heat up from 130degC to 235degC in less then 10 sec to keep the tool change short. The inactive hotends are cooled down to 130deg when in standby.
Repeatability is perfect with zero issues after hours of endurance tests and all the printing tests.
The printheads are hold in place by cones and strong magnets, nothing fancy needed.
Different nozzle-heights for every hotend are no problem at all, the bed is adjusted during the tool change automatically to fit the corresponding tool.
For now, this is all tested to the very end and supported by Smoothieware and S3D natively, no special coding or hacks required.

I just read an article from the +3D Hubs newsletter, regarding "3D Printing low-run injection molds". Actually, I have a real need for a "low-run" of injection molding. Does anybody know a source, where I can order a run of like 100 to 300 parts?

I designed, tested and produced a water cooled heatsink for the good old E3D-V6. For more info, visit: http://well-engineered.net/index.php/en/shop/water-cooled-heatsink

80$ DHL-Express shipping does take only 22 days delivery... Probably. It is still on its way...
