Ender 3 Pro BMG Direct Drive Nozzle as Probe

thingiverse

I've stopped developing this model as I have upgrade to the BLTouch. I've upload the Fusion360 and STEP file for anyone who whats to continue to develop this further. ----------------------------------------------- Update V2: Complete Redesign. Alright! This has been completely redesigned, almost from ground up. I decided to keep the back plate similar as before so that it still remains a remix of sorts. After numerous tests, I've redesigned the shroud to have a more flexible hinge which has a physical bottom stop to remove any snag dude to huge or fatigue. With the system being a direct drive, you get a lot of the support from the PTFE tube so there is very minimal movement. The shroud is much smaller than the original and now has a larger part cooling fan duct to improve cooling and be overall a neater package and retain the stock 4010 fan. It is recommend that you remove the metal tab on the limit switch, this is reversible. I've aligned the M3 screw at the limit switch directly underneath the button. This greatly improves the performance of the probe making the Z distance less than a millimetre. Enjoy! ----------------------------------------- Update V1.1: Made it easier to install. ----------------------------------------- Original: This is a Remix of TechingTech's CR-6 style Nozzle as Probe ABL system. I needed it to work with the BMG Extruder in the direct drive setup, so I needed a custom mounting plate. Please watch TeachingTech's video for full instructions on installation and Marlin setup. https://youtu.be/hs6IVfNrf5k
