To Build a Caulking Gun / Paste Extruder for the MPCNC, Follow These Instructions Carefully This device requires several key components to be printed in PLA with specific parameters, then assembled according to the visual diagram provided. - **Key Components:** - Three parts must be printed using the recommended PLA settings: a layer height of .3mm and an infill level of 25%. The necessary prints are four small cylindrical elements for the bearings, one larger cylinder for the gear box assembly, and one part to house the NEMA17 stepper. - **Hardware Needed:** - A length of all thread rod measuring five-sixteenths inch (5/16") is necessary, as well as three-fourths (3/4) inches six-twenty-two hardware. - **Components:** - You'll also require compatible nuts to secure the rods in place. - **Stepper Assembly:** - A 6-32 NEMA17 stepper is essential for the mechanical motion. To Build a Caulking Gun / Paste Extruder, Follow These Instructions Carefully First, two identical gears known as "39T17" must be printed to enable gear interaction between the two major assemblies. The gear size indicates an odd tooth count. Once all parts have been completed and all necessary components have been acquired, assemble the device based on a comprehensive picture reference to avoid confusion. The 608zz bearings should sit at specific spots indicated on the blueprint and aligned to allow seamless movement within these housings provided. It is also important to secure all major pieces in place before powering up for first operation since proper configuration requires initial verification without power activation, as improper assembly might compromise motor functionality and possibly induce premature motor wear upon its operational state post startup
