[MDD v1.2] Ender 5 BMG DD V6 with BLTouch

thingiverse

It appears that you've provided instructions for assembling and configuring a 3D printer mount for a BMG+V6 hotend with linear rails. Here's a summary of the steps: **Materials Needed:** * M4 screws + 1x M4x20 (for fan mount to fan duct) + 1x M4x25 (for fan mount to base) **Accessories:** * Stopper for sensorless homing with linear rails (optional) * Self-locking nut (if using M3x25 screws) **Print Settings:** * Print base and cover without support, layer height 0.2 or less * Print fan duct with support on build plate only * Use 20% infill and at least 4 perimeters * Line width of 0.4 instead of 0.4x for increased accuracy **Installation:** 1. Prepare base by inserting nuts (BL Touch, base, and M4 for 5015 fan) 2. Screw base onto stock plate with 3x M3 screws (8mm length or longer) 3. Insert BMG+V6 mounted together (with all 3 screws already in place) 4. Add stepper motor and tighten the 3 screws 5. Insert nuts into cover 6. Screw cover onto base with 3x M3x30 screws 7. Cable management 8. Mount fan duct using M4x25 screw and M3x8 screw (check height) 9. Add BLTouch with 2x M3x8 screws 10. Final cable management **Firmware Setup:** 1. Set BL Touch offsets (nozzle to probe offset) * Define NOZZLE_TO_PROBE_OFFSET { -42.12, -4.44, 0 } * Z offset should be around -2.4 (adjust for nozzle/hotend) 2. Limit print volume * Check MAX Y/X values for yourself (critical step to avoid crashes) **Important:** * Make sure bed moves freely on top (loosen and tighten linear rod holders if necessary) * Firmware adjustments may require changes to Marlin settings (e.g., X_BED_SIZE, Y_BED_SIZE, X_MAX_POS, Y_MAX_POS)
