Having some difficulty printing small 6mm x 6mm cubes on mt TAZ 6 using PLA. I need over 500 of them and the first batch of 48 came out acceptable. But now they are not sticking to the bed and are being lifted by the nozzle. As the nozzle is putting down plastic it is picking up what is down and dragging it to the next cube. Then everything goes bad. Nozzle set at 205 and the bed at 60. I am using Cura 2.6.66 slicing software.
