This blog post is a living documentation of my Wanhao Duplicator 6 / Monoprice Maker Ultimate printer.

• printer.cfg -- Klipper config
  • Bltouch support
  • 10x10 mesh height map calibration
  • Force move Z without homing
• petg-superslicer-config.ini -- PETG settings for SuperSlicer
  • Features a prime line after heating from 05, 30 -> 05, 170 -> 07, 170 -> 07, 30
    • This eliminates the need for skirts or brims!

If you wish to use these configs as a starting point for your Wanhao D6, you may want to consider the modifcations I've made. Without mods, the Wanhao D6 is basically unusable (in my opinion)

Mods:

• OEM enclosure
• Microswiss all metal hotend and slotted heat sink
• Triangle Labs direct drive extruder (mounted with Bondtech machined metal mount and Bondtech PCB holder)
  • Replaced the extruder motor with a pancake motor to prevent build area loss
  • 42x42x23mm, 1.8 deg. step angle (200 steps/rev), 1A/3.5ohms/4.1V, 13Ncm
• BLTouch
  • Mount: https://www.thingiverse.com/thing:4108601
  • wired to both the z limit connector and analog connector. Power is from the analog connector pins 2 and 3, servo signal is z limit pin 1, and limit function moved to analog pin 1.
  • Wiring diagram: (taken from dot bob)
• Left and right hand mounted 24v 4010 radial fans wired in parallel into PCB fan slot (no build area loss!)
  • Left mount: https://www.thingiverse.com/thing:4802449
  • Right mount is on my github wanhao-d6-config repo (fan_R_holder.stl) -- credit to tqzr from above thingiverse link for sending me the step file
    • 
• Silicone boot for hotend -- important to avoid cooling down the hotend and prevent errors: https://www.thingiverse.com/thing:2216683
• Wire management clip for the direct drive mount
  • https://www.thingiverse.com/thing:3762718
• Mirror on top of build plate (removed the buildtak the printer came with)

Non functional (ish) mods:

• Feet to allow airflow: https://www.thingiverse.com/thing:1580480
• Hole plugs to prevent filament/crap from going to the electronics section: https://www.thingiverse.com/thing:2872888
• Steam valve knob: https://www.thingiverse.com/thing:3152876
• Custom crimped 16 pin dumont cable to replace the flat 16 pin IDE cable
