Help with Reprap x400 (modified?)

Hi guys,

Sorry if this is in the wrong forum. I could not find a suitable forum for this post.

I am new to 3D printing and I am stupid so instead of buying a 3D printer that was easy to use, i bought a 2nd hand reprap x400 which seems to be modified. I am looking to replace the whole extruder assembly and hot end assembly, but i was wondering if anybody could help me identify what i have here or what would be compatible to replace it with? Any help would be appreciated. I've included some photos of the setup.

Thanks

... "German Reprap GmbH" is not "RepRap", but a separate company, which was cooperating/exchanging around one year with the community, but went their own way after.

You can try to find related infos ... if to no avail, then find and replace the electronics with a board with proper documentation ...

Sorry for all the edits I lost the links had to re-find some of them.

It has much information that you can use to do almost every thing you may want.

Repetier x400 Firmware (v2.2.1) you can use the profile information here to change to Marlin it you would like.
It has profiles for many filament .

Plus quite a few Technical Support Documents

thank you so much for the help. i found out that it is a reprap x400 CE. I found a picture of the nozzle it uses, does anybody know what nozzle that is?

It appears that you have already found the correct manual though I will post a link for download location.
Maybe if one of our better 3D Printer enthusiast look at the design of " The extruder > Der DD1-Extruder or Der DD2-Extruder in this manual.

They may tell you that a simple conversion to the upper mount could be made to use something like a J-Head extruder. they look so similar to each other in upper mounting hardware

DD1 Extruder In Pages 98-105
DD2 Extruder In Pages 106-113
Hotend in pages 114-116

Was "stupid" enough too to pick up a same machine but with DDR3 extruders. Have you been able to move forward with it? Found the DDR3 E3D combo is somewhat workable but as it does not have a part cooler fan I decided to, and am in the process of, exchanging it with a Qidi hardened steel nozzle dual extuder set used in the I-Fast. Might be interesting for your machine too. That it lifts the extruder not in use is a very usefull feature preventing damaging the print surface or kicking the print loose from the bed.
Once that runs I plan exchanging the Arduino board with a more up to date one capable of running Klipper. If all that runs it should be a great enclosed large volume proffesional dual extruder machine capable of the most challenging prints and materials. And in my case for a very reasonable price as the printer is a pro-grade very solid built machine with only 17 days printing time total in 8 years. Total estimated cost with all replacements and modifications less than 700 euro..
