Mini DVD Motor 3d Printer

thingiverse

DISCLAIMER, this design utilizes motors and smooth rods from DVD drives; however, I cannot guarantee its compatibility with all DVD drive parts if they vary or are non-standard. This project was undertaken as a scrap project, so if you wish to replicate it using purchased DVD drives, the parts may not fit without modification. Additionally, DVD motors require lower current than typical 3D printer motors, and motor drivers will need to be adjusted downward to prevent overheating. EDIT: April 19th, 2020 - Added "Z Base R2" which reinforces where rods interface with the Z base. Also added "Z Carriage 3.3 R2 Slotted," a modified carriage design incorporating slots taken from its original placement along the smooth rods to enhance tolerances. Furthermore, I've included "Long Clip," two of these clips effectively secure the glass in place. EDIT: June 2nd, 2019 - Added remix of a pi zero case to facilitate headless printer operation over USB: https://www.thingiverse.com/thing:3668215 EDIT: May 19th, 2019 - Added mount for attaching the titan extruder motor adjacent to the printer. EDIT: May 18th, 2019 - Introduced new "carriage teeth" files featuring curved designs that provide improved grip on the leadscrew. Additionally, I corrected the orientation of these teeth, which were initially installed incorrectly, resulting in their rapid deterioration. New files for the Z base and Z carriage have also been added to enhance the Z carriage's length along the smooth rod. EDIT: May 12th, 2019 - Efforts are being made to improve the Z axis as it has encountered issues with binding. A longer carriage design is under consideration to prevent twisting and binding during printing operations. This project draws inspiration from existing designs utilizing DVD drive components; however, I aimed to create a compact and neatly designed 3D printed frame that accommodates standard parts. Instead of assembling full metal DVD drives and resulting in a DIY appearance, this design seeks to offer a more refined solution. I recommend this project only for individuals with basic knowledge of 3D printers, soldering skills, and an abundance of patience. The process requires some tweaking to achieve the optimal leadscrew tension, which can be challenging but essential for smooth operation. Leadscrews will eventually wear out, necessitating replacement using a 3D printer. The printer operates on an MKS GEN L controller, chosen for its affordability and compact size. A 12V power supply is required; I utilized a 12V 80W laptop-style PSU attached with a DC plug to the printer. The hotend assembly consists of a clone e3d, while the titan extruder sits nearby on the floor. The board runs headless over USB, an oversight that could have been avoided had I realized its lack of a built-in SD card reader. The "carriage teeth" file includes two versions; when replicating this project, it is advisable to print multiple copies in PETG for enhanced durability and flexibility. These components are prone to wear and require precise tension on the leadscrew without over-tightening. If anyone decides to create this design, please share your make in the comments section below. Any queries or concerns can be addressed through these comments due to the limited instructions provided. The build volume of this printer measures 40*40*36mm with the glass installed on the bed. Note: The e3d fan mount attached to the heatsink is not part of the original design and was not created by me. A link to this design can be found at https://www.thingiverse.com/thing:1658075#
