XYZ DaVinci CoreXY Mod

thingiverse

I modified my XYZ DaVinci because the design is, rubbish. So many issues with it, it's clumsy, noisy, not very well aligned and slooow. So I designed a CoreXY modification, reutilising as many parts as possible, but replacing useless parts like the appalling hotend. Now my DaVinci can print PLA at 80mm/s with excellent accuracy and quietly, no more screeching on fast moves. oh and travel speed is 200mm/s. This mod requires that repetier firmware is installed, and that you have selected corexy in config.h Luc's Firmware4DaVinci is what I used and it works well, Luc has done a great job with the port. https://github.com/luc-github/Repetier-Firmware-4-Davinci I'm not offering any support on this, which is why I have included a link to the Fusion360 design so you can adjust to your own requirements. EDIT: Autodesk have made if difficult to share this, so please find attached STEP files. Check the revision history of the drawing for parts to suit your requirements, during this process I used an E3D v6, slice mosquito magnum and a precision piezo for probing, so chances are theres a revision which has the parts you'll require.There's even a revision which supports genuine gates GT2 idlers, oh and various part cooling solutions. Where possible I have tried to use existing mounting holes for screws in the frame, but I noticed not all davinci's have exact same positions (even between same supposed models). You may need to mod the design or grab a drill. Please don't attempt this project if you don't know what you're doing, this is a very advanced mod. If you have questions about how this fits together; then this project is beyond 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 about 1.6m length each 4x Lock Collars like these https://ooznest.co.uk/product/lock-collars/ to fix the Idlers in place stop movement of the linear rail against the motor mounts. You will need to swap around the motors as they are different sizes, I swapped the extruder motor with the X motor so they are a matched pair for the XY motion. I have since this switched to a Duet2 WiFi and am currently redesigning for HIWIN linear rails so I can't offer any support on this design as my reference platform has been dismantled. All I have left are the drawings and a couple of photos, which I have shared here.
