Just got my Flashforge Creator Dual and here are my first prints

[repman]

Try increasing the build speed to 90mm/s extrude and 150mm/s travel

also heated bed is not required, and only causes more heat - heat is PLA's enemy

mounting a small fan to aid cooling the part as its printed will also help, PLA being of low density retains heat easily and needs help to get rid of it

these printers being makerbot copies are optimized for ABS, so you may get better results by using ABS, with these settings, but still increase the extrude and travel.

Keep it up
