A pancake motor with a minimum of 16N.cm and 1.8° or 0.9° resolution To complete the upgrade, some firmware modifications are necessary. The community firmware with LA1.5 from Vertigo235 has been used in this example, and can be downloaded at https://github.com/vertigo235/Prusa-Firmware/releases. For the X carriage, consider using Vekoj's design found on Thingiverse at https://www.thingiverse.com/thing:3748932. The provided files include step files and F3d files for easy assembly and modification. Update 1 (August 31, 2019): A new body version has been added, along with a hinge featuring a 2mm recession to eliminate the need for threaded inserts. These modifications are denoted as "WITHOUT" in the STL file list. Note that this design change will reduce the overall length of the screw by 1mm, affecting the heatbreak fan assembly. This new design has not been thoroughly tested; users are encouraged to try it out and provide feedback on its performance.
