Ultimaker 2 BMG Conversion (1.75mm) Accessory
thingiverse
Hi, These are just two accessories that could be handy for an Ultimaker 2 BMG 1.75mm conversion: 1) tube-holder: reuses the bowden-tube as cable-guide 2) Y-endstop-extender: BMG stepper motor will crash into the UM2 housing without it You will also need: - "Ultimaker 2 BMG direct drive mount" by Tigerhawk60 (www.thingiverse.com/thing:3798359) - Bondtech BMG extruder - "Tinker-Firmware" by TinkerGnome (github.com/TinkerGnome/Ultimaker2Marlin/releases) - V6 groove mount compatible hotend (24V Heater Cartridge, PT100 Thermistor) - small piece of 1.75 mm bowden tube - custom slicer profile I would also recommend to print everything from ABS or similar temperature stable. There are also aluminium UM2 BMG direct drive mounts on AliExpress, but be careful, you may have to modify (drill/mill) these to get them working. Also it's quite heavy and the included linear bearings are trash. In retrospect I would recommend to start with a 3D-printed one... You will probably need to replace your heater cartridge, so do at your own risk.
