XYZ DaVinci CoreXY Mod

thingiverse

I modified my XYZ DaVinci because its original design is utterly flawed. Countless issues plague it: clumsiness, noise, misalignment, and sluggish performance. Determined to resolve these problems, I designed a CoreXY modification that leverages as many existing parts as possible while replacing inadequate components like the woefully inadequate hotend. This transformation enables my DaVinci to print PLA at 80mm/s with impressive accuracy and minimal noise, eliminating the screeching sounds associated with fast movements. Travel speed has increased to 200mm/s. This mod necessitates that Repetier firmware is installed and CoreXY selected in config.h. I employed Luc's Firmware4DaVinci, which performs admirably, a testament to Luc's exceptional work on the port. https://github.com/luc-github/Repetier-Firmware-4-Davinci I'm not offering any support for this project; hence, I've included a link to the Fusion360 design, allowing you to modify it according to your specific needs. EDIT: Autodesk's restrictions have made sharing the original files challenging. Please find attached STEP files instead. The revision history of the drawing contains various parts tailored to your requirements. During my process, I utilized an E3D v6, Slice Mosquito Magnum, and a precision piezo for probing. You'll likely discover a revision that includes the necessary components, including Genuine Gates GT2 idlers or diverse part cooling solutions. Whenever feasible, I've employed existing mounting holes for screws in the frame; however, I noticed discrepancies between different DaVinci models, even those with identical specifications. You may need to modify the design or use a drill to accommodate these differences. Don't attempt this project unless you're thoroughly familiar with its intricacies; it's an extremely advanced mod. If you have questions about how the components fit together, then this project exceeds your capabilities. Rough parts list: * M4 Screws and lock nuts * M3 Screws and lock nuts * M3 nuts * 8x IGUS Drylin 8mm bushings (like these https://www.amazon.co.uk/gp/product/B01M4JZ81S) * 8x GT2 Idler pulleys (like these https://www.amazon.co.uk/gp/product/B07K8CB8JN) * 2x GT2 Timing belt, approximately 1.6m in length each * 4x Lock Collars (like these https://ooznest.co.uk/product/lock-collars/) to secure the Idlers in place and prevent movement of the linear rail against the motor mounts You'll need to swap the motors as they differ in size; I swapped the extruder motor with the X motor to create a matched pair for the XY motion. Since then, I've switched to a Duet2 WiFi and am currently redesigning the system for HIWIN linear rails. Consequently, I can't offer any support on this design, as my reference platform has been dismantled. All that remains are the drawings and a couple of photos, which I have shared here.
