Assembling : drive module

Step 1

Preparation of parts machined in CNC: Unlike the 3D printing, CNC machining with a cylindrical cutter produces rounded inner corners. Whether file or dig with a mini drill (1,8mm recommended) rounded areas circled in red, to make right angles. You also should drill from side to side the part indicated by a red arrow with a 5mm drill and expand the upper part of the hole to fit a nut M5 – caution, housing for the nut must be smaller than the nut so that it can be pushed in only by forcing (see step 12).
