So I've managed to get two Titan extruders up and running on my BigBox. I spent several hours this morning getting used to the firmware as the bed levelling is currently done like the pro (ABL) rather than the dual (mesh). Once that was sorted I went for a traditional square, hidden amongst a collection of others I've previously done, some really bad, can you guess which is the Titan one? Next up, the 'Titan-ic', aka Benchy, here on the left, alongside one I had previously done on the right, one of the first few prints ever on my original BigBox. All good fun and games but I wanted to test the other Titan so it was time to calibrate: Nice! At this point OctoPrint started playing up and then I got a clogged nozzle, after a pull apart and clean it was time for a dual Dizingoff print with E3D PLA black and Scaffold PVA in grey: This was a 4:30hr print. Below is the waste: Tomorrow I will dissolve it and post the result!!
