Troubleshootings FAQ on ET4 and others

Today, we collected five main difficulties that users have with ET4.
Luckily, they are all not big problems. Only a little fine-tune and checkout can just figure them out.

For some issues, we have independently released their approaches before, so here we just posted their links. 

Read on to see if there's anything that is your concern.

Q: The printing process is skipped from 0% to 100% very quickly or in one blink, with the extruder completely out of command.
A: Format the SD card or change a more high-quality one. This solution also fits the issue that the SD card can't normally show up the sliced files 

Q: The Cura setting is not compatible with ET4
A: Now Ultimaker Cura4.5 has had a built-in setting for various Anet printers. Click the link to learn the details

Q: The automatic leveling malfunctions. For example, the extruder stumps on the print bed, or it constantly hits the top limit switch.
A: This issue has perished after we developed ET4 firmware 1.1.5 ( Now there’s little need to worry about that. But we still recommend you to go to Youtube to see a specific video demonstration done by one of our colleagues. (  There you can also learn other things like how to handle blocked filament.

Q: The nozzle cannot be heated when starting printing or in the middle of the printing process or when pressing the "pre-heat' button the nozzle has no reactions.
A: This problem is usually caused by not tightening the cable tie with the wire harness well. If this problem has happened, you should disassemble the extruder to check whether the heating tube (the line labeled "end") is burned or use a multimeter to check whether the resistance value of the heating tube is about 15Ω. And according to the result, you need to decide whether to buy a heating tube and remember to buckle the cable tie to it tightly.

Q: ET4 bricks after firmware updating
Before updating the SD card must be formatted.
If the machines have already broken after updating, you need to buy a J-tool to flash the firmware. And the tutorial we also have in our official blog.

Q: The body of models is full of disgusting staggered strips. (see below)
A: Open any version of Ultimaker Cura and click [preference].
Remove the  √ of [Enable Coasting].

Lamento haber comprado está 3D, funciona muy bien, pero con el firmware bloqueado no existe mejora posible, si se rompe el hosted, la extrusora la electrónica, solo tendrá la carcasa, tendré que transformarla y pasar de esta marca.

Creo que es mas que esos puntos, en mi caso compré la anet a un distribuidor de mi ciudad, Tengo l version que hace ruido, el extrusor es super malo patina por todo, y el hotend ni hablar constante tapado de boquilla de verdad la mejor solución que pueden hacer a míles de usuario que la compramos es abrir el firmware para poder colocar un hotend y extrusor diferente, muy triste la poca calidad de la máquina
