G3DK Projekt

Hello! This is my G3DK project. The set contains the following items: The complete extruder (Chimera Chinese version) including belt holder, fan holder, LED holder and cable holder. The stepper motor holders for the Z-axis. Stepper motor holder for the X-axis. This construction is based on the linear guides MGN12, the upper stepper motor brackets are pushed onto the guides and held by themselves. If this does not occur, there is a hole for screwing in the holders. The motor couplings MUST be free of play! The linear guides are mounted laterally and the distance to the frame is very small to minimize vibrations and levers. This makes the print much cleaner. The X-axis holders are designed for 2020 extrusion. I would print the stepper motor holders and belt holders made of PETG because this material does not break and is very tough. During my first attempts with ABS, I broke the belt holder. The belt wedges hold the belt perfectly and do not require any screws. There are various Chinese extruder designs. The top three holes may need to be adjusted. The holder for the radial fans is also included. I did not upload a nozzle because I am still dissatisfied with it. I will upload them later. I recommend printing the belt holders with at least 50%. Also, the bracket for the cable holder. The rest can be printed with 30%. As a fan, I use an E3D-Titan Aero fan. This is switched on and off automatically at 70°C. With this conversion, I can print PLA up to 180mm/s without any problems. You can find the belt tensioner for the X-axis in my other projects. I took the chocks from the belt holder from another project, this is Remix. Unfortunately, I cannot find the link to it anymore. EX = Extruder parts MO = Motor parts Z = Z-axis parts
