Build Instructions

The build instructions below are divided into two parts, namely pre-assembly and final assembly. In the pre-assembly some of the sub-assmeblies or parts are either prepared or assembled together to ease the final assembly. The numbering system below will be referred to within the build manual by appending each number after the previous number for eg. the LM12UU bearing installation is in step 1.4.1 and can be looked up in the list below as part of the Build Platform assembly > Z-Axis Bearing Holder > LM12UU Bearing. The number in the (#) paranthesis denotes the quantity of the part.
