I've got my toolchanger alive again (gathering dust for ~3 years, life got complicated). It moves, picks up two tools, and has laid down the first layer of a single color PLA benchy (badly, need to work on z-fine-tuning) My goals: have fun goofing around with another printer get some multi-color PLA prints going avoid frustration as much as possible. I've currently got two tools built: T0: Hermes (pre-Hemera) direct drive with standard v6 HE T1: Hermes mounted on the frame top, bowden, v6 tool I've got pieces for two more heads from early 2020: two blank tool plate kits two mosquito hot ends two bondtech BMG-M extruders one E3D Slimline Stepper Motor (0.9) one stepperonline slim stepper 0.9: 17HM08-1204S It seems like I can build two direct drive hot-end. The e3d motor one about 350g, the other about 300 (without screws/heater/wires). My original Hermes tool is closer to 450. I have not used a mosquito yet, more experience with v6, Rapido, and a bit with Revo. My plan: Phase1: overhaul the current tools, new nozzles, etc. level the bed and learn how duet bed-mesh-leveling works get a clean benchy set up a superslicer or prusaslicer profile get a clean multi-color test print read through 3 years of posts here to catch up on collective-wisdom! Phase2: add X/Y endstops (the violent X sensorless homing is not confidence inducing) think about improved z-offset measuring (actual nozzle touch?) build some new tools Any advice or things to watch out for would be most welcome...

My TC was as well gathering dust, family increased. At first I have to scan this forum for any news and developments of the last years. I remember that I stopped before Phase 2 point 2. Measuring the z-offset for each nozzle is a thing that was a pain for me. There must be a way to have an automatic touch measurement. Did you already reach Phase 2? And I still lack part cooling fans.
I completed the z-Offset measuring for my toolchanger. The z-leveling for all the tools seems to work. I added a microswitch next to the heat bed as a second probe. That button is touched by cold and clean nozzles. Then the zOffset can be adjusted. I did upload the macro/script and my probe configuration here: https://github.com/Nibbels/e3d-toolchanger-config (Commit ced125fc64f49c17ea184e546eea64f1fa0748b2 and 2b580d78ff7a25591c705b3e4f39e3e0824c1199) https://cad.onshape.com/documents/0...c59ea62c25377e2e7b/e/f313093ca67e5584a46cb220
