My inaugural duration test with the dual head setup yielded a print that required approximately 10 hours to complete and involved more than 400 tool head changes. Despite some remaining calibration issues, the final product was a nice clean print. The settings used for this print included a 15mm retraction on tool change and a +0.5mm compensation for leakage, with layer thickness set at 0.2mm and fill density at 15%.
