Wanhao D6 Induction Probe Mount

Updated 2-28-2017 The hookup photo has been updated to better illustrate how to wire the probe and LM7805 to the controller board. Updated 2-18-2017 Mathieu Fabris converted the "Marlin_firmware_How2Flash" manual to French. It is available on his website: http://www.printer3d.one/fr/tutoriel-installer-firmware-marlin-1-1-limprimante-3d-wanhao-duplicator-6/ Updated 2-9-2017 The "Probe_Calibration.PDF" manual has been included. This project provides all the necessary information to add auto-bed leveling (mesh bed leveling) to a Wanhao D6 (Monoprice Maker Select Ultimate) printer. It relies on a recent build of Marlin 1.1.0RC-8 and an induction probe that can be wired by yourself. First, you will need the firmware, and this project would not have been possible without the hard work of Rob Mendon! He went above and beyond the call of duty on this firmware. This firmware has been tested and screened for bugs as best as we could. There are many features specifically targeting the D6 in this firmware, making it not a plain vanilla Marlin port. The source code and instructions on how to build and install it can be found here: https://github.com/dot-bob/Marlin/tree/Wanaho-Duplicator-6 You may also need information on how to build the latest version of Marlin firmware on your machine. The instructions are in the "Marlin_firmware_How2Update.pdf" file. If you do not have a probe, I highly recommend using a 12mm induction probe. A 12mm probe with the included mount will not hit any part of the machine, and you will lose no build volume. The recommended probe is available on this website: [insert link]. The offset settings for the 12mm and 18mm probes are as follows: // Front side Mount -- 12mm Probe offsets #define X_PROBE_OFFSET_FROM_EXTRUDER 35 // X offset: -left +right [of the nozzle] #define Y_PROBE_OFFSET_FROM_EXTRUDER -15 // Y offset: -front +behind [the nozzle] #define Z_PROBE_OFFSET_FROM_EXTRUDER 0 // Z offset: -below +above [the nozzle] // Back side Mount -- 18mm Probe offsets #define X_PROBE_OFFSET_FROM_EXTRUDER 35 // X offset: -left +right [of the nozzle] #define Y_PROBE_OFFSET_FROM_EXTRUDER 52 // Y offset: -front +behind [the nozzle] #define Z_PROBE_OFFSET_FROM_EXTRUDER 0 // Z offset: -below +above [the nozzle] If you need any information on Marlin configuration, I recommend visiting this source which explains everything and what each setting does/means: http://marlinfw.org/docs/configuration/configuration.html After installing the probe, now you need to calibrate the probe height to the build plate. This is covered step by step in the Probe_Calibration_Updated.PDF. It also includes the required G-code that needs to be added to your existing slicer starting script. Print Settings: Printer: Wanhao Duplicator 6 Rafts: No Supports: Yes Resolution: 0.2mm Infill: 75% Notes: I print my mounts in ABS. You might be able to use PETG as well, but PLA will sag as the probe mount is very close to the heater block. I only recommend printing with ABS. Print at 66% or higher infill. I printed some at 75% infill and others at 66% infill. The more solid the mount, the better. When printing with ABS, I recommend a 101% scale. This will counteract the ABS shrinkage. The tolerances on this part are pretty tight, so it WILL make a difference! Post-Printing: Check fit before installing! The overhand, even though it is small, needs to be near perfect. It is a tight fit, so if there is not exactly 8mm between the lip and the base, you need to sand/file until there is. Especially if the support left any nubs or plastic behind when removed. How I Designed This: Mount modifications are possible! I have included the 123d Design files, though if you change any part of this design, the offsets and/or the pre-calibration distance will no longer be valid.
