The Davomatic is a Cantilever design printer. I choose this style because I had saw a lot of cantilever printers on Open builds and other tinkerer site but only a few that had been successfully built and saw that as a challenge. This build was built with off the shelf openbuilds parts and other various parts found on THingiverse.com. I did find out why this printer had such an unpopular following. it has been a challenge building this, but the actual design and build wasn't that hard, but it was a bit challenging to get it to print nearly perfect parts due to the amount of vibration generated during the printing process. I am successfully printing functional parts. More on that later in the build process. I am labeling this as a work in progress because I want to completely eliminate the vibration which is the final step in getting this printer to any resemblance of a professional grade printer.

Special Notes
This Build is actually Completed, but I am still working on tweaking the vibration I am having in the final prints. I have gotten them to an acceptable print quality but want to perfect it further. will re-post my final firmware. By the way, I am using Marlin 1.1.8 for this build!

Reason for this Build
I choose this style because I had saw a lot of cantilever printers on Open builds and other tinkerer site but only a few that had been successfully built and saw that as a challenge. This build was built with off the shelf openbuilds parts and other various parts found on THingiverse.com. I did find out why this printer had such an unpopular following.Inspired by
Indie i2's success let me know that it could be built, and I wanted to increase the build volume. -
