When using Repetier for Slicing I am having a unique problem, it prints beautifully and consistently until it is printing little pillars and it has to move back and forth from pier to pier at which time it quits printing the PLA. I have tried all types of setting and nothing seems to help. The piers are typically less then a 1/4" and it is just printing the piers when it happens. I have had this happen on several different prints. Has anyone had this problem and if so how did you fix it. I am running the 4.8.1 Repetier.
