Hey everyone,

So I'm new here a looking for some help. I'm working in a lab and we purchased a Makerbot Replicator 5th Generation at the beginning of the summer. It worked amazingly well for about a month, but now whenever I try to print a large object I get a "heat sink" error. The machine will make it about halfway through the raft, give me the error, and then stop printing. I was wondering if anybody had any advice as to how I might fix this?

Thanks!
