Hot End Enclosure, for Reach3D Printer

thingiverse

This is a detailed guide on how to assemble and install the BLTouch sensor on a Reach3D printer, along with some additional instructions for using an E3D v6 hot end. ### Part Assembly Overview The assembly involves attaching various components to create the final setup. Each component requires specific steps for attachment to ensure proper functionality. ### Step 1: Print Parts and Clean Them - **Print the parts**: This step involves printing all the necessary parts as per the BOM (Bill of Materials) list provided in the description. - **Clean all the parts**: Ensure that all parts, especially the insert nuts, are free from any debris or imperfections. Cleaning is crucial for a smooth assembly. ### Step 2: Attach Hot End Clamp to Enclosure Main Body - Use M3x20 screws and nuts to attach the Hot End Clamp to the Enclosure Main Body as shown in the guide. ### Step 3: Prepare Radial Fan Insert - Add an M3 nut to the inside insert for the bottom screw on the radial fan before adding the fan and its shroud. This is a critical step to ensure proper alignment and assembly. ### Step 4: Install Proximity Sensor - Slide the Proximity Sensor through the top hole of the Proximity Sensor Block, ensuring that the "clamp split" is open. - Add an M3 nut for adjusting the height of the sensor and attach it with M3x20 screws. ### Step 5: Final Assembly Steps - **For BLTouch**: - Add M3x10 and nut to the "back" hole in the BLTouch, ensuring about 1.3mm from the BLT surface. - Insert the BLTouch into the bottom hole. - Add a nut for height adjustment and screw down with an M3x40 screw, then add the locknut loosely. ### Step 6: Final Adjustments - Bring the BLTouch up to the block and slide it on to the "back" M3 screw. - Adjust the gap between the top of the block and the BLT for optimal performance. ### Additional Instructions for E3D v6 Hot End - Do not use the Fan Shroud for Stock Heatbreak or Standard Hot End Clamp with Nutinsert when using an E3D v6 hot end. ### Configuration for BLTouch Offset and Bed Probe Position The provided Marlin configuration includes offsets for X and Y (30 and -26 respectively) and positions for probing on the bed (LEFT_PROBE_BED_POSITION, RIGHT_PROBE_BED_POSITION, FRONT_PROBE_BED_POSITION, BACK_PROBE_BED_POSITION). ### Final Note Adjust the Z height offset as per your setup's requirements. Use `M851 Z-2.25` and then save with `M501`. Adjust this value to match your BLTouch sensor's height adjustment for optimal performance. This guide provides a detailed step-by-step process for assembling and installing the BLTouch sensor on a Reach3D printer, taking into account specific settings for an E3D v6 hot end.
