First few layer squish and y-axis noise issues solved!
Solved the mysterious squish problem and the horrendous noises coming from my printer. I just noticed that the y-axis belt was pretty loose out-of-the box. My y-axis motor went out and I noticed it when I went to replace it. I replaced the y-axis motor with this: https://www.amazon.com/gp/product/B07LF898KN/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1. I had to trim the stem a few mm so it didn't hit the build plate. I also replaced the plastic pulley with this: https://www.amazon.com/gp/product/B077GNZK3J/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1. I also replaced the tensioner bearing with this: https://www.amazon.com/gp/product/B01H3FNZ4M/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1. I noticed that the stock tensioner bearing did not have enough of a lip on it, and the y-axis belt would slip and rub on the plastic. I also made sure that the belts were all better aligned. Finally, I replaced the z-axis motor with the same unit that I replaced with the y-axis. Notably, these motors are completely plug and play (other than having to trim the stem down. Base layer prints perfectly now.
