Today I went and tried out a few new settings. I changed the numbers so that the dimensions were a lot more accurate. Then I went and even though the extrusion rate was too much, I increased it further because it didn't seem like it was flowing together nicely. For another cube, I increased the printing temperature and it seemed to bond together better. I have a suspicion that it's reading the temperature wrong and so I may need to further increase the temp. Regarding the motor slipping on the X-Axis, I realized that was one of the motors I had not upgraded yet, so that may be one of the things I do soon so I can avoid any more layer shifting, especially since I already have the motor.
