The E3D Tool Changer printer beta build

By SublimeLayers Monday, December 31, 2018

I have the good fortune to be one of the early betas (aka Guinea Pig) for E3D's amazing Tool Changer. At its heart, it is a CoreXY with an open front - which eliminates the one issue I have with Core XY format - you can't see it print clearly! This printer is not a "kit" in the sense that not all components are supplied. But the core (no pun intended) of the mechanical printer is included. The X-Y motion platform (Core XY) is fully assembled and ready to go as is the Z axis. The printer requires 7 stepper drivers so a Duet (Wifi or Ethernet) and a Duex2 or Duex5 board are required.

I was the second person to receive the overnight delivery from the UK (the first was in Europe). It came nicely packed in one large box. I got started putting it together immediately. The main printer frame went together in short order. The parts are beautifully machined and fit perfectly.

I chose to use four Bondtech BMG extruders (two normal, two mirrored are required) rather than the recommended E3D Titan. That's the only thing I deviated from the recommended build. What can I say. I love Bondtech extruders!

I didn't take a lot of photos of the build as E3D's site linked above has very clear and detailed photos of the printer. I wanted to get this beast built so I could calibrate and start exploring its capabilities.

In addition to the Tool Changer core, E3D will offer a wiring harness kit - which I highly recommend. Once installed it will look like this:
The "most challenging" part of the build was printing the required parts. I used SnoLab's Carbon Fiber PC+ as it is remarkably strong, high temperature resistant and looks fantastic. I did print a few parts in their Sublime Green PLA+. As I write this, I'm waiting for the last part to print that I overlooked. Of course it had to be literally the last step in the build - installing the IEC switch. I forgot to print the housing/bracket for it! It is 30 minutes from completion and then I'll be ready to commission the printer and get to work exploring its capabilities. Stay tuned!

  1. Found this website because E3D posted a link on twitter. Thank you for documenting this! Looking forward to a follow-up post!
