Just building a BigBox Dual "the Works" with Titan upgrade. I only had one E carriage for titan. I cannot find anything detailing how the dual Titans are meant to work, what parts are needed, and what I should be looking for. The regular dual parts have been deleted, so it seems that I have no other options. I am confused about how it is meant to be configured, but I would like to build dual direct Titans. The printer is not built, so I cannot print out new parts. Seems E3D needed to give instructions with the dual upgrade specific to BigBox, but I cannot find them! Any help is much appreciated!
