BL Touch Bed Leveling Sensor

Post by Sindarius » Tue Jan 22, 2019 2:40 pm

This is a work in progress

This mod is to add a BL Touch probe to the Crane Quad for bed leveling. I have collected several resources and put together the script files that you'll need to implement this.

I have created a mount to mount the BL Touch to the QuadFusion print head that you can get here - https://www.thingiverse.com/thing:3368042

I have attached my configured files to this post which contains all the system file changes I have made to get the touch working and some macros to help with testing and adjusting.

This is a list of resources I referenced when putting this all together. There is great information on how to wire up the BL Touch to the Duet 2 Maestro Board in this documentation.

Once you have the build complete you can add a G29 call before every print to rebuild the mesh or you can run it on the duet web control manually.

Notes
Once you have this build complete you'll want to lower you z limit switch or remove it completely since it can potentially trigger during probing which causes invalid results.
