Thank you Roberts_Clif I will read up on this.Also thank you for a different post you made where you suggested slowing down the prints speed and the cooling fan. Mine was running 100mm and 100 fan. Slowed that to 30mm and 50 fan and i think stuff looks better. Im still learning and with the great advice and people ive ran across here i am learning slowly Oh and im up to 3 printers now in 2 months I might have a problem
