Tell me if it works for you or not.
Hello, I checked the sensor. I sent all the details to your email info@sovol3d.com I bought the printer from Amazon, with extended warranty. replacing the thread sensor with that of extruder 2 works. I have always had this problem. Does the warranty cover the thread sensor?
Yes, the warranty cover the filament senor. You need to send the video showing the problem, then the order id and manufacturing code to that email. The customer service will help you.
Yes, I sent an email to this address and also through Amazon, is info@sovol3d.com correct? otherwise, being the first printer, where can I find the code of the machine? thanks for the help! I am a technology journalist, I will soon be making a very positive review of my Sovol 04, then send links to you, if you like! below I put the link of the first job done with your printer!

There is a qr code under the hotbed, which is the code. That email info@sovol3d.com is correct. Also, you can send email to our Amazon. No matter which one is okay. We’ll check and respond to you quickly.
It is our pleasure if you like to make a positive review for Sovol 04. 
Your printing is amazing. I like it!
