I noticed problems with my build platform that was preventing me from printing a full set of chess pieces at once. So I've spent the past couple of days re-leveling and testing and got that thing just as right as I could and the test print I was making still didn't stick. So I took the step I didn't want to. I mixed myself up a batch of ABS glue and spread it on the build platform and the result was brilliant... and ugly.
By the way, that ABS glue is also useful for making minor modifications to existing prints using bits past failures. Great stuff. Glad I've got it around now.
