FIVE TROUBLESHOOTINGS ON ET4

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 posed their links. 

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

 

Problem

Solution

1.

The printing process is skipped from 0% to 100% very quickly or in one blink, with the extruder completely out of command.

Format the SD card or change a more high-quality one.

2.

The Cura setting is not compatible with ET4

Now Ultimaker Cura4.5 has had a built-in setting for various Anet printers. Click the link to learn the details https://www.youtube.com/watch?v=9Nx0E3ir_8w

3.

The automatic leveling malfunctions. For example, the extruder stumps on the print bed, or it constantly hits the top limit switch.

This issue has perished after we developed ET4 firmware 1.1.5 (https://shop.anet3d.com/blogs/download/et4s-newest-firmware-update-1-1-5-has-released). 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. (https://www.youtube.com/channel/UC1rrZAGhaadjeVJMi8CGAsQ).   There you can also learn other things like how to handle blocked filament.

4.

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.

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.

 

5.

 ET4 brick 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.
