First Layer Print Issues


#1

Hi,

I am new to 3D printing and have a FlashForge Creator Pro printer. I am having an issue with the first layer of a PLA print job that is uneven and missing spots (see image, sorry a little blurry but I’m talking about the 2 squares on the left, the right had started its second layer when I took the picture). I’ve done the bed leveling multiple times and am pretty sure I got it good, and have been printing in ABS with little issues. I’m using mostly standard settings with the exception of First Layer Height, which is at 100%, First Layer Speed at 43% (out of 4200 mm/min)?

Please help.

I didn’t find the right solution from the Internet.
