That leaves four months worth of stuff to talk about. It&#8217;s a huge amount to blog, so I&#8217;ll be breaking it up into multiple parts, and I&#8217;ll post the parts on different days.<\/p>\n<h3>Stuff From Before My MiniMug Post<\/h3>\n<p>For my January 3rd post I jumped ahead and immediately posted the pic of me celebrating my minimug. I still have stuff from before then to post.. Here&#8217;s the best I can do from memory and piecing it all together from pictures (as always, there are a lot).<\/p>\n<p>First of all, I&#8217;d fixed my X-axis problem as I said two posts ago, but little did I know that I had a subtle Y-axis problem too (that I just hadn&#8217;t noticed, because of my large X-axis problem). But I hadn&#8217;t figured that out yet. All I knew was that my horrible X-axis problem was solved, and parts looked way better.<\/p>\n<p>So, I printed some parts (which, again, still weren&#8217;t perfect, but I didn&#8217;t fully realize that yet).<\/p>\n<p>A calibration piece (lit by a flashlight I loosely attached to the frame):<\/p>\n<p><a

My Y-axis was still using the old McMaster pulleys from before, and although it hadn&#8217;t caused any huge noticeable problems like my X-axis had, it did cause problems. The calibration piece at the top of this post shows it best &#8211; the infill of the object was crossing over the perimeter that had been drawn &#8211; I was accumulating Y-error. The fix involved removing my bed, so that I could loosen the belt, so that I could remove the Y-axis motor, so that I could get off the pulley, and replace it.<\/p>\n<p><a href=\"https:\/\/www.keegan.org\/reprapblog\/wp-content\/uploads\/2011\/04\/IMG_3336.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.keegan.org\/reprapblog\/wp-content\/uploads\/2011\/04\/IMG_3336-1024x768.jpg\" alt=\"\" title=\"IMG_3336\" width=\"450\" height=\"337\" class=\"alignnone size-large wp-image-2265\" srcset=\"https:\/\/www.keegan.org\/reprapblog\/wp-content\/uploads\/2011\/04\/IMG_3336-1024x768.jpg 1024w, https:\/\/www.keegan.org\/reprapblog\/wp-content\/uploads\/2011\/04\/IMG_3336-300x225.jpg 300w, https:\/\/www.keegan.org\/reprapblog\/wp-content\/uploads\/2011\/04\/IMG_3336-768x576.jpg 768w, https:\/\/www.keegan.org\/reprapblog\/wp-content\/uploads\/2011\/04\/IMG_3336-1568x1176.jpg 1568w, https:\/\/www.keegan.org\/reprapblog\/wp-content\/uploads\/2011\/04\/IMG_3336.jpg 2048w\" sizes=\"auto, (max-width: 450px) 100vw, 450px\" \/><\/a><\/p>\n<p>I replaced it with a printed pulley, put it all back together, and tried printing another calibration piece.

I&#8217;d determined previously that in order for it to be alcohol-tight, I needed to cram plastic together. I changed the ExtrusionInfillWidth from 0.7mm to 0.5mm, and plastic globbed everywhere, making a nice alcohol-tight minimug (which looked much more bumpy on the outside).<\/p>\n<p>Here was the first of the recent attempts, which was close but not even water-tight:<\/p>\n<p><a href=\"https:\/\/www.keegan.org\/reprapblog\/wp-content\/uploads\/2011\/04\/IMG_3376.jpg\"><img loading=\"lazy\"
