CAUTION!, read carefully the documentation.
The Tronxy X3 printer needed to be modified in order to work properly because originally the alluminium heating block is inside the fan case. This is leading to several temperature problems: block not reaching the proper temp to melt filament and heatsink not cooling the filament due to the transmission of the heat via hot air and via throat... Those problems were solved as described in the document and in add you have a stl file with a creation of my own wich is a layer cooler called TRONRECOGNIZER because of its shape... It seems the flying machine of the film and in add, it almos coincide in name with the brand TRONxy ;-)

Hope you like it and that you find useful the entire document. Thanks for reading/downloading.

And thanks to c4sfer, from the Telegram Tronxy 3D printers Spain group who told me to put alluminium adhesive tape to keep the air in the case fan. And thanks the whole Tronxy 3D printer Spain's Telegram group for your help and support.
