Built my Anet 3D Printer on the weekend of Irma, started on Saturday evening and ending on Monday. Mostly.
Printed two things, the new fan nozzle and a part for the feather robot. Both seemed to have gaps and holes, googled that and got this info.
1. You are under extruding. Raise the extrusion multiplier by at least 5%.
2. Slow down print speed.
3. You have loose belts and excessive play in the printer (the A8 has tons of play it’s really junky but fun). If you don’t add a tensioner to the belts, it’s tough to keep them tight.
4. Raise the temperature to 230. The A8’s temperature probe is off on my unit.
