Tips to get the best results with All Metal Hotend:

• Reduce retraction amount. All Metal Hotend needs a lot less retraction.
  We had luck printing PLA with as little as 0.5mm retraction, without oozing. For PETG, try 1.0mm retraction.

• For PLA, you might need to increase extruder temperature 10-15 degrees.

• If the temperature is not stable after conversion, PID tuning might be required.

• Highly recommend changing stock Wanhao i3 extruder gear to D4 style gear.
