Failed, but big prints

Well, the raft was beautiful until the extruder failed and started stripping plastic on the first print layer. For the record, that raft is 125x148mm.

The scaled down raftless version (94x75mm) was looking good until the extruder stripped after an hour of printing.

My build surface is about 155x180mm. Technically I could make it slightly wider.

But I'm starting to hate the extruder hot end with a passion. My Cartesian bot is great, but the extruder is still crap.

I've been eying that MK5 extruder a lot lately...

My extruder body seems to work fine but it's undermined by the flawed hot end. You still want a copy? I dunno if it can work with the Mk5.

I think I'm going to Make Do until it's time to do the full transition to MK5. And what might wait for the next MakerBot I get.

Gad, there are so many technological steps between this and the general assembler... early adoption is going to be expensive -__-;

I wonder if you can toss some kind of flow check on the head, so the program is paused when the feed strips...
