Titan Aero – Extruder Replacement Part 1
Titan Aero - a good extruder for the less demanding
I would like to share with you my latest upgrade to the 3D printer Ender 3. I decided to change one of the most important parts in the printer. My choice fell on TITAN AERO from triangular ones. I read a lot of positive comments about it, so why not give it a try. I chose the triangular ones because it's just an experiment so I didn't pay much attention to buying a super uber original, a good replacement was enough, nothing more. I also wanted it to be the Direct version.
Below are links to purchase the appropriate components:
- Ender 3 Printerfrom aliexpress
- Titan Aero from Triangelab
- easy assembly
- versatility (choice of direct and bowden options)
- a large number of spare parts
- quality (everything is folded quite well and the performance is good)
- use of the gear ratio
- gear wheel + knurl very similar to those used in BMG extruders
- no assembly instructions available
- no BOM list or something similar
- no list of step settings and gear size (could be created for the most popular printers)
Or maybe the instruction? Not necessarily, you have to do it yourself
Extruder came packed in one small box. There were a lot of parts in it. With this amount, you can choose whether to mount in the bouden or direct version. The set is so complete that it won't be a problem. We also have components for different filament thicknesses. However, one thing I missed, unfortunately, the instructions for the 3D printer itself were really well prepared, but unfortunately there is no. But not being discouraged by this fact, I undertook the assembly. I will try to show you step by step how to properly assemble, connect and adjust TITANA.
Foreplay first, then we will undress ... the extruder
The first step before spinning the current Extruder should be a 3D print of the appropriate adapters and trolley (carriage) for the new extruder. As there are several versions of the TITAN AERO, you need to look for the right version or of course design yourself. I was able to find a corresponding version of the Ender 3 enhancements for the Titan Aero extruder.
Once we have the mounting elements ready, it is good to check what we have in the box. I have prepared all the elements that interest me. It is worth noting here that the version I received was already pre-assembled extruder but unfortunately it was not completely assembled because the heat sink was missing the filament guide tube. This is a very important element when printing. It helps to guide the material correctly so that the flow does not clog. After adding this element we have a ready set for connecting a stepper motor.
Then you need to start spinning the existing version. It is worth to pack all the elements separately. It should be remembered that the cart and the stepper motor feeding the filament should be unscrewed. It is located on a slope next to the vertical z-axis guide.
Once the printer is ready for assembly, the cart printed by us should be attached with two screws. This is necessary at this stage because the screw holes will be obstructed by the motor.
In the next step, we change the gear on the stepper motor. It is included in the set, it should be screwed onto one small screw.
Then attach the stepper motor with extruder to the trolley. You should get there well with the motor shaft. We fasten everything together with three screws. To the trolley on the right we screw the windmill responsible for blowing air on the filament. We attach the second fan to the second printed detail. We put this part directly on the radiator. The kit includes a mounting element with a fan but smaller so I decided to use the current one.
It is necessary to heat the atmosphere
Included with the hotend are two wires. One of them is a heater that we do not have to replace because in the nominal version it is exactly the same. However, we have a different temperature sensor. It should be changed to match the current version. To do this we need to get to the motherboard. It is in the front part where the entrance to the SD card. When we open the cover we get to all possible connected cables. We need to replace the cable with the current sensor with a new one. When we do this, we close the lid and continue assembly.
Important note: a 12vdc heater does not necessarily work well in a 24vdc system
Note number two: connecting a 12vdc fan does not result in better blowing, but the effects are amazing ... flashes, smells and more
Now HOTEND should be attached. We screw it with a screw. We put the heater into it and tighten it as well as the temperature sensor. We can now connect the stepper motor to the power cable. Here the cable should be connected to the motor rotated 180 degrees. In the extruder we use gears with one gear. If we leave the current connection, the stepper motor will pull out the material. The easiest way to reverse rotation is to connect the reverse power supply. It is worth starting the printer here and turning on the hotend heating. In this way we will check whether everything is well connected.
Just connect, calibrate PID, do print calibrations and it's ready
We've got an easier extruder change page. It took me a lot more problems to set all parameters correctly to have good print quality. In the next part I will describe how to do it correctly.
