Wanhao Duplicator i3 V2 - PID Autotune Process

Temperature control is critical in 3D printing. Unfortunately, the Prusa i3 clones typically come with PID temperature control disabled. Using any program that can talk to your printer directly including Octoprint and Repetier host, you can setup PID and use the built-in auto-tune process to get much better temperature control.

The following video walks through the process on my Monorprice Maker Select (a clone of the Wanhao Duplicator i3).

PID Autotune process for Wanhao Duplicator i3 V2, Monoprice Maker Select and Cocoon Create.

1. In any system that provides terminal access to your printer via USB (Repetier host, Octoprint, etc) enter the command M303 S230
2. Wait for process to finish and gather Kp, Ki and Kd values
3. On the printer; go to Configuration - Extruder
4. Set Control to PID
5. Set DT/PID P to the value of Kp
6. Set PID I to the value of Ki
7. Set PID D to the value of Kd
8. Go BACK ⏎
9. STORE to EEPROM

Wanhao Duplicator i3 V2 - Stepper Tuning

Image
The stepper controllers on the Melzi board inside the Wanhao Duplicator i3 V2, Monoprice Maker Select and Cocoon Create are incorrectly tuned for the stepper motors. The Wanhao Google group again has some great information on the symptoms here. Using that information, I created a video on how to research the data on your own stepper motors and correct the current being sent to them for cool and quiet printing.

Wanhao Duplicator i3 V2: Flexion Extruder Install

Image
Printing with flexible filaments such as TPU provide a whole new set of project opportunities. The problem with these filaments is guiding them through the filament path without them squirming their way out. The great team at Diabase Engineering which includes one of the inventors of Ninjaflex, solved the problem. The Flexion extruder controls the filament pathway and compression in a very elegant solution. The kit includes a full extruder replacement of every part except the stepper motor. Take a look at the video installation and the challenges that go with installing this great piece of kit. I was able to print a replacement bike handle for my daughter. It took a few tries to print (mostly due to a difficult design on my part) but works great. You'll notice a seam about 1/4 of the way through the print. I did get a jam in the extruder but was able to measure, reslice and resume the print the next day.
