So a little update on the Dual Extrusion Y Splitter I’ve been working on. I’ve spent the last few days trying to pin everything down with it. I’'ve updated it a little and tightened up the filament path to just a hair under 2mm, (Can’t say exactly how much due to filament shrinkage and printer tolerance, it’s about 1.9-1.95 though). YMMV with the model on Thingyverse (see my previous post as it’s all down to how tight your printer tolerances are. I’ve tried it with various PETGs/Copolymers (HDGlass, Extrudr PETG, Colofabb XT & NGEN) and they work without an issue, the crux is this though, PLA will jam and quite possibly block your Splitter. Permanently. Not too much of an issue for me as 99% of what I print is PETG or Copolymers.
Tool Change Scripts are almost there, I’m still getting a little over what it should be to get the filament back into the nozzle in the best place and not get any filament being pushed out and I need to work out how to force retract between the purge tower and model to kill strings, also I need to make the tower wider to kill color bleed. With all that being said. Have a video of it in action on the new FB2020 - Harlequin (More on that when it’s joined the farm).
