Not sure what's causing the gash, if it's too much or too little plastic, but it sure is annoying... It seems to start small, then get wider and wider as the print progresses.
the part I'm currently printing is a 1cm^3 (1 centimeter cube)
Here's a picture of the problem:
|I colored the flat area on the side with a sharpie, so that you can see the gash, there's also what looks like a bunch of bits of plastic fused to the part on the other side of the gash (where there's a bunch of dots).|
