# Mount for the BL Touch for the Ender 3 and similar probes and machines This mount is designed to hold a BL Touch in position for the Ender 3, and all other printers with similar X-carriage (many Tevo's, CR-10, etc.). It allows access to the hotend without having to disassemble the BL Touch every time. You can reach the two screws without any problems. # Assembly 0. Print the three parts. 1. Mount the BL Touch to the holder. 2. Start screwing the bolts. 3. Before you finish screwing the bolts, insert the shim, then finish screwing the bolts. 4. If the extended BL Touch doesn't reach the bed before the nozzle does, or it's too close, place a 2mm thick spacer between the holder and the probe. ## Extra Hardware - Two M3 bolts at 10mm length (the original ones are 8mm length). Optional: - Two M3 spacers. ## Probe Offsets - X axis: 51.112mm to the left. - Y axis: 8.300mm to the front. Marlin configuration: #define X_PROBE_OFFSET_FROM_EXTRUDER -51 #define Y_PROBE_OFFSET_FROM_EXTRUDER -8 #define Z_PROBE_OFFSET_FROM_EXTRUDER 0 # Z-Offset Z-offset depends on your particular machine and hotend, and can even change with nozzles. You'll need to calibrate your own z-offset. Your z-offset should be negative, meaning the probe (when the prong is extended) is touching the bed before the nozzle does. If your z-offset is zero or positive, it just won't work, because the nozzle will push the bed down, and the "measurement" will be meaningless. For that, print the "BL Touch 2mm spacer.stl" and use it as a spacer as needed. You can scale the spacer in the Z dimension (non-uniform scaling) to suit your needs. A typical z-offset is about -2.0mm. The probe should be down enough so will hit the bed before the nozzle, and up enough so it won't enter into contact with the printed part. ## Compatibility Tested Machines: - Ender 3 Tested Probes: - 3D Touch by Triangle Labs (AliExpress)
