With this, I want to sum up all basic upgrades, mods, some suggestions and more.
I have made a little test print you can try to print. You can download it here:

If you have the original I3 Mega, and want to be able to print TPU, you therefore can upgrade to the Mega S with this kit:
But with the new extruder, you need a new firmware and/or change and calibrate your E Steps.
For this you should check out this post: Firmware |

The Ultrabase is the best bed, I ever have used. But it must be clean!
Clean it! Before every print, I would suggest, that you clean it. Just take some isopropanol and give it a wipe with a towel. I use this: Please don´t use Aceton. This will destroy your bed.

Y-Tensioner
I still haven´t tested this. But if you want, you can go for it: Y-Tensioner Bed isolation The bed has no isolation, further a lot of heat is lost and the heating takes longer. Therefore, you can install a isolation. |

I still use the original hotend, therefore I will only show upgrades for this one.
But I´m planning to upgrade. Cover/Case So first, I made a new Cover with bigger (Honeycomb Style) holes, for a better airflow: Hotend Cover For this cover, I would recommend that you change the right fan for a silent one like this: The left turbo fan is quite good, and I would keep it. It cools the part enough.

Covers and cable management
This is just a little cover, doesn't do much, just protect the cable: cable holder When you print high objects, the cable may get squeezed at the top. I use this little cable guide: cable guide For this, you must cut the old cable ties and put new cable ties on it. |
|
Tool Rig
This is just a nice tool rig. You can put all your tools in. Nothing more to add. Tool Rig And a holder for your caliper: Caliper Holder |
|
Vibration
The printer can sometimes vibrate very much. The simple way: Just put some foam (when you order something, you will get some for sure) under the feet. It will help some, but not for long. But I still use it (I just order enough). Nevertheless, you can print this: Squash Feet These ones are not as high. (with my guide, you don't need to mount the power supply fan outside, so the printer doesn't need so much space beneath it.) For this vibration dampers you need 4x Squash Ball: |
|
Lighting
I don´t have any lightning installed on my printer. But this is the next thing I want to do. Ok, so there are basically 2 variations. Lightning on the hotend, or lightning on the housing. For the Hotend: A ring lightning which directly lights the printed part: Ring LED Holder A compatible led would be: Important! If you also have the fan duct installed, you need this one: Ring LED Holder 100mm Furthermore you´ll need to buy the bigger 100mm Ring LED Or you just glue some led´s into the cover. You need some 12V LED.
To install it, just connect it to the right fan cables.
For the Housing: A led stripe around the printer. To mount it print this: LED Mount And a led strip: You can cut the strip and just connect it to the powersupply.

Motor Driver Fan duct and Fan
Ok, next on the list is the fan next to the power supply. For this, I would recommend printing this fan duct: Fan Duct Again, you also need a new, not as noisy fan. You need a 40mm x 10mm fan: For the fans, use the included orange plastic things to tighten them to the cover or fanduct. They reduce the vibrations a lot.Paragraph.

So if you have the swappable drivers you can go on.
If you have the board on the right picture you can only buy a new Trigorilla board. So, you will need 5x TMC 2208: (for: X, Y, Z, E0 (Extruder), E1 (second Z) There are some different versions on the market. If you can find some, which are called V2.0 you just can swap then out. Also, when you get them, check again if they are really V2.0 If you don´t find any, or got delivered others, you have to flash a new firmware. Be sure, to then take the right hex file (Marlin-AI3M-vx.x.x-TMC2208.hex). You can find more to this under the section Firmware. I recommend these: Now to the installation:
Look at the marks on the board and on the driver, don´t put it in in the false direction. When you install it, you must also check the voltage and probably change it. For this you will need a mutlimeter.

Z-Wobble
Ok, maybe you have noticed it, maybe not. But the clutches for the Z-Axis are very stiff. Therefore I changed them with better ones. These ones are much more flexible and will eliminate any Z-Wobbling.
But the installation is kinda pain. You must unscrew the motors from the top, and then put the clutch out. When you have the opportunity, you should take the screw drive out, and clean it (You will never do it again). After cleaning, put a some oil or lubricant on it again. |
|
Mosfet
Personally, I don´t have one. But there is a slight chance, that the motherboard could get to hot. Furthermore, it could than be destroyed. You can print this Mosfet Holder: Mosfet Holder He also explains how to mount it. And then buy two 2 pieces of this mosfet: |

The Mainboard
|
The original Hotend
|
The Ultrabase bed
|
Orignal Nozzle
|
Thermistor
