I printed the same gcode file as in my last post but with the temperature set to 250c- that made a huge difference. Each layer successfully bonded with the layers around it, I wasn't able to crack it by squeezing it as hard as I could. Still need to tune the layer heights etc so that it's not so oozy.
Changing the temperature also allowed the ABS to adhere to the "Artist Plastic Palette" that I got from the craft store. (google "palette 0010321", there's at least one available online).
