To ease up the process of bed leveling, BL-touch is one of the handiest upgrades you can get for a 3D printer. While it’s great in performance and provides a tremendous advantage, there is one issue that you may face. You may sometimes see the Bltouch blinking red during print. Why does that happen, and what can you do about it?<\/p>\n\n\n\n

When the Bltouch starts blinking red, it usually means that it has gone into alarm mode. This problem happens when the probe fails the self-test. A lot of things can cause this failure. Another reason for the probe to blink red very slowly is damage to the wiring. Fixing the problem requires you to figure out the reason first.<\/p>\n\n\n\n

I am pretty sure; you are still confused about why this happens and how to fix this. I recommend sticking to the end of this article to find all the answers you are looking to get.<\/p>\n\n\n\n

Reasons for the BLtouch to blink red during print<\/h2>\n\n\n\n

Now, Bltouch usually blinks red in two different ways. It can either be a slow blinking red light or a faster blinking red light. The two distinct patterns indicate two other things. I will go through both of them and show you why each scenario occurs. So, let\u2019s get going.<\/p>\n\n\n\n

When the lights are blinking quickly<\/h3>\n\n\n\n

First, let’s get through what happens when the Bltouch red lights blink rapidly. This problem indicates that Bltouch is in alarm mode. It occurs whenever the machine fails to pass the self-test process. It’s a process where the probe will check up on the whole thing and see whether it’s prepped up for use.<\/p>\n\n\n\n

Here are the reasons for this to happen \u2013<\/p>\n\n\n\n
