Tronxy XY2-Pro Direct Drive

thingiverse

There are plenty of Direct Drive conversions around for the Creality printers, unfortunately none of these will work on the Tronxy, the mounting position for the hotend is 9.4mm to the left on the tronxy. So, I reverse engineered the [Direct Drivinator](https://www.thingiverse.com/thing:3589452). My end result isn't so pretty with filleted corners etc. but it's dimensionally perfect for my XY2-Pro. I also added a mount for a cable drag chain and created a mounting to fit the X axis motor screws. The chain itself is a [Creality CR-10 X axis cable drag chain](https://www.thingiverse.com/thing:2923095) I printed 14 top links and 14 bottom links to create the chain. Changing to direct drive bypassed the filament detector, so I created a mount for the top of frame that would hold the switch and a couple of pieces of bowden tube to smooth the path of the filament. To reconnect the switch I removed the bottom cover from the control box and found the cable connecting the board to the ribbon cable (see the photo), I removed this and extended it to run up the frame directly to the switch. Printing: The parts, as orientated shouldn't require any supports, I used 1.8mm walls (0.6mm nozzle), 1.5mm top and bottom and 50% infill.
