Wanhao Duplicator Plus Titan Aero Mirrored Mount by spengineer

Last crawled date: 3 years ago

V2! (V1 is still included as Mirror_Carriage_2)
This is a mount for the Titan Aero extruder/hotend that fits the Plus. The mount can work with either the original motor or a small 26mm pancake stepper like this one. (Though you will lose a little travel if you re-use the original one.) It's meant to allow you to add a the new extruder while keeping the dimensions and overall shape as close to stock as possible. In fact, you should be able to re-use many of the screws in the original carriage for the installation of this one. Though I recommend using low profile M4 cap head screws, since that's what the holes were actually sized for.
This is using the Mirrored 24v Titan Aero.
I have included a printable lower bearing block to make the mount compatible with the Ciii Cooler.
Belts attach as they do on the original printer, there are two holes in the back of the mount that you are able to thread M4 bolts into, the belts are then secured around those in whatever way you like.
Dimensions should be pretty similar to the original in terms of travel.
Remix of http://www.thingiverse.com/thing:2178694 to fit the Wanhao Duplicator i3 Plus (also known as the Monoprice Maker Select Plus). V2 also takes some design cues from https://www.thingiverse.com/thing:2698296, by AldiPrinter.
DIRECTIONS

Remove old carriage, leaving only the top bearing. Keep the screws from this, as they'll be re-used.
you can remove the bottom bearing by loosing the bottom x rod on both sides, and sliding it over until there is enough space to get the bearing off the end.
(I'm just going to write how I did it from this point on)


Attach the printed bottom bearing using M4 screws (I used M4x20, but anything between 10 and 20mm will work) being careful that the bearing does not interfere with where the motor cable will be running.


Put together the extruder following E3D's instructions. Make sure, however, that the direction the heater block is turned when tightened does not interfere with the cooler.


Put the whole assembly so far onto the printer by sliding the bottom bearing onto the already loosened rod, replacing the rod, then attaching the top bearing using the original screws. Once both bearings are attached, make sure the bottom rod is aligned and re-tighten the grub screws on either end holding it in place.
Also attach the belt. I had to adjust the length to make it tight.


Connect the various wires to the extension board. this will require some cutting and crimping, mainly since the heater block wont fit the original heater cartridge and thermistor. a helpful guide to the board layout can be found here. The motor wire will need the center two wires to be flipped if you're using the slim stepper from E3D, or have all of the connections reversed if you're using the original motor.


Finish the hotend installation. (you'll need to heat it up and tighten the nozzle, then add the silicone sock) Then attach the Ciii Cooler (or whichever one you're using) onto the bottom bearing block using the un-occupied holes.

Finally, adjust the stepper motor current if necessary. For the E3D slim stepper I had to up the current from the stock 1.02A to 1.26A.
After it's all together, make sure that everything works as intended. Mainly that the extruder is turning in the right direction. Also re-run e-step calibration, Bed Leveling and PID tuning.
If you're set on using V1 (it does give a little more room on Z), the see below:
This cooler will most likely work with this design. I think you would have to use the "Titan_Aero_Shroud_360_Mirror.stl, specifically.
You can use this design from gilcv to attach the bearings and belts.
