Once I calibrated the printer properly and verified I was making pieces in the proper dimension, the next step was to start improving the printer. Many things I had simply stuck together with hot glue and things I had lying around. The endstop supports and endstop flags were one of these things, made out of a cut up credit card and glue. Another issue I was facing was the ability to feed the plastic into the machine. I had the roll sitting next to it and would have to untangle it by hand every few minutes. To fix this, I printed a support for the roll that I still use today.
