Dual extruder settings

Hello. So far i have not been able to successfully print a two colur object using the dual extruder on my A305T. Specically has anyone successfully produced a print using PLA and either breakaway support or soluable support. If so, can you kindly tell me what settings you used and maybe include a picture of the printed object. I’d also be interested to know if any has successfully printed objects using different filament types eg PLA/PETG. Again settings and advice would be appreciated. Kind thanks
