RAMBo door disassembly
For MK2.5 there is a redesigned RAMBo cover case and door. In the following steps we will remove the older parts completely. Proceed with caution, as you might break the cables.
MAKE SURE you won't mix old and new parts!!! Their design is sometimes similar.
Using 2.5mm Allen key, remove the M3x10 screw together with the upper hinge.
Remove to the RAMBO cover door.
Using 2.5mm Allen key, remove the M3x10 screw together with the lower hinge.

Slightly release two M3x10 screws holding the RAMBo cover on the frame. DO NOT unscrew them completely!!!
Carefully slide the RAMBo cover from the frame. Plugged cables won't allow you more than few centimetres.
Separate the cover from the RAMBo board.

In order to match the wrapping style of the printer, an extra textile sleeve is included for the X-axis motor cable. You can remove the spiral wrap and replace it with the textile sleeve, or leave the wrap in place. It is up to you, this step is optional ;)
以下のステップに向けて、下記の部品を用意してください:
Textile sleeve 6 x 300 mm (1x)
Zip tie (1x)
Wrap the sleeve around the X-axis motor and endstop cable. The sleeve is shorter, than both cables.
結束バンドを使って、スリーブを固定します。このとき、必ずしっかりと固定してください。これは Einsy ケースの組み立てまでに一時的に必要なプロセスです。ケース組み立て後もそのままにしておいても問題はありません。
Note the rest of this chapter was photographed with the spiral wrap, but the assembly procedures are the same for the textile sleeve.

4 個 の M3n ナット を ナット の穴に入れます。
Slide RAMBo inside the base and tighten it with four M3x10 screws.
ネジを締める時は、細心の注意を払って締めこんでください。ボードにダメージを与える可能性があります。

Different cable clips
Cable bundles are held in place by cable clips, which HAVE DIFFERENT SIZES of the inner cutout. Please ensure you are using the CORRECT CLIP for each cable bundle!
RAMBo-heatbed-cable-clip is used for a smaller cable bundle, therefore its opening is smaller.
RAMBo-extruder-cable-clip is used for a bigger (thicker) cable bundle, therefore its opening is bigger.

Insert both M3n nuts in the traps on the RAMBo-cover-base, see the picture. Make sure the nuts are all the way in.
Take the Rambo-heatbed-cable-clip and press it against the heatbed cable bundle.
Using M3x10 screws fix the clip in place, tighten both screws equally.

Original Prusa i3 MK2.5 upgrade brings several improvements from the MK3, however, there are not enough pins on the on RAMBo 13a(10a) board's connectors. Using v-cables we will split one cable into two connectors.
Take v-cable for the PINDA V2 probe and connect it to the PINDA probe cable from the Extruder.
Take v-cable for the Left hotend fan and connect it to the Left hotend fan cable from the Extruder.
Quick check: PINDA probe is using 4 wires, therefore, you need to connect v-cable with 3+1 wires.
Press the cable bundle from the Extruder in the hole on RAMBo-cover-base. Make sure the spiral wrap is partly in.
The nylon filament stays as a part of the bundle. No need to separate it as on the older versions of the RAMBo cover.

Using M3x10 screws fix the clip in place, tighten both screws equally.
Read the text and pictures in the next step carefully, as you need to connect the v-cables to multiple ports!
This step was photographed with the spiral wrap, but the assembly procedure is the same for the textile sleeve.

Extruder motor (yellow label with "E")
Extruder heater
Extruder thermistor (yellow/green heat shrink, orientation does not matter)
Front print fan (red heat shrink, ensure that the red wire is closer to the extruder thermistor connector)
Filament sensor cable (use the correct row of pins in the connector and ensure the red and blue wires are facing the outside of the board) In the third picture, the RAMBo board is facing with the USB port towards you.
