JGAurora A5 3D-Touch sidemount

thingiverse

This thing allows to mount a 3D-Touch bed leveling sensor to the side of the printhead. It fixes two major issues I had with other mounts: * It does not collide with the frame when moving the Z-gantry all the way up. * It avoids long levers and thus better constrains the Z-position of the probe. There is a version that puts the sensor as close to the nozzle as possible and one that is compatible with the famous [BlowHard 3000](http://www.thingiverse.com/thing:2757866). Prints without supports, best at 0.1mm layer height. Use 3-4 wall lines and 5 top/bottom layers for more stability. The mount places the sensor some 36mm in the X-direction and 8mm in the Y-direction from the nozzle, depending on your exact printer geometry. These values need to be entered in your firmware configuration. For Marlin this would beby changing the following lines in `Configuration.h`: #define X_PROBE_OFFSET_FROM_EXTRUDER 35 #define Y_PROBE_OFFSET_FROM_EXTRUDER 8 #define Z_PROBE_OFFSET_FROM_EXTRUDER -1.5 Or, for the BlowHard3000 compatible mount: #define X_PROBE_OFFSET_FROM_EXTRUDER 37 #define Y_PROBE_OFFSET_FROM_EXTRUDER 12 #define Z_PROBE_OFFSET_FROM_EXTRUDER -1.5 Please check one of the excellent HOWTOs out there on how to install the sensor and update your firmware. The Z-offset denotes how far the sensor trigger point is from the nozzle - thus it is always a negative value. Typically this should be around 1.5mm, again depending on your printhead and sensor geometry. After installing the sensor, home your X-axis and carefully drive the printhead to the right side. Check if the sensor collides with the X-axis holder before reaching the maximum of 305mm. If so, consider reducing the X-size of the printbed in your firmware settings, just to be on the safe side.
