And in this other line of the code we are going to indicate that our installed sensor is a BLTouch / 3DTouch, which for Marlin come to be the same. You may notice a variety of options for the new Ender 3 V2 firmware. Here’s what you need to figure out. Motherboard type

Furthermore, when there is a mains power cut, a small UPS device such as the BTT UPS 24V will notify the mainboard of a power outage. The printer will then prepare accordingly. As the BLTouch going into alarm mode can be a result of many different things that go wrong during the self-test process, here is a list of the common culprits that accommodate most cases but isn’t exhaustive:You can get more information about the color scheme of the wiring here . Why Is My BLTouch’s Red LED Always On? But before we look further into the collection of different macro commands for RRF. Let us begin by showing how to install or add new macros commands via the RRF Duet3D Duet Web Control (DWC). Manually adding a macro While unoptimized BLTouch start G-code can also perform the task of auto bed leveling without issues, as long as the code does not contain invalid syntax, reducing the print time as much as possible is a significant addition to the printing process. Optimized BLTouch Start G-Code for Cura (Compatible with Ender 3 Pro/V2)

Before you close it up, note the version of your mainboard (4.2.2 or 4.2.7). It’s written in the center of your mainboard. BLTouch is controlled by hall effect, providing high precision. Thus the bed material can be freely selected.Now we must uncomment the AUTO_BED_LEVELING_BILINEAR function and then the RESTORE_LEVELING_AFTER_G28 function, so that they remain active in our firmware. BLTouch is an auto leveling sensor for 3D Printers that can precisely measure the tilt of Bed surface. It could work with any kinds of bed materials, such as glasses, woods, metals, and so on.

I was able to get Merlin flashed to my Ender 3 V1 with a 4.2.7 board that I got a few days ago. I imagine I will soon be a patron to get into your discord but wondered if you could throw out any suggestions for this problem.

To further aid in visualising the BTT SKR Mini E3 V3 pinout for the TFT connection, I have used a custom cable in the imagery above to match the table below. For example, the far-left Yellow wire is the Reset, and the far-right Red wire is the 5V connection. RESET For mounting, you will then need the appropriate M3 screws* to screw the BLTouch to the mount and the mount to the Ender 3 V2. Furthermore, the connection of the BLTouch / 3DTouch sensors to the boards is relatively simple and you do not need to carry out any electronic modification as it happens in other sensors. Some Chinese sensors indicate operating ranges from 6-36v, nothing is further from reality. If you feed them at minimum values ​​they don’t work, so you have to feed them at 12v. As with everything else in the 3D printing realm, the BLTouch can come with problems of its own at times, with the issue of a red blinking light being the most commonly talked about one in the community, which will be our topic today.Once you have the firmware bundle from Creality, you will want to unzip the folder and find the actual firmware file you need. In my example, I want to get the “Ender-3 Pro- Marlin2.0.1 – V1.1.2 – BLTouch.bin” file that’s under the “Marlin2.0.1 BLTouch V1.1.2 without transfer board” folder. Just one important thing. In the case that connecting the 2 wires to the Probe connector the sensor not works, try to connect to the ZMin connector. Depending of the firmware version of your Marlin, in some cases it gives issues, but if you connect to ZMin it will work perfectly.

The famous BLTouch sensor from ANTCLABS from South Korea! The BLTouch is a 3D printer bed levelling sensor that enables automatic bed levelling on your 3D printer regardless of the printing surface. The engineering pin can safely protect your 3D printer from inexperienced operation and the bent protrusion caused by the shrinkage of the output during printed.Furthermore, I have listed both the original and alternative wiring colour codings from top to bottom. Importantly the bottom wire is GND (Brown or Blue) and is closest to the thermistor connections, and the White probe SIGNAL is nearest the USB port. BLTouch Alternative Wiring The last thing you’ll need to figure out is which version you need V1.3.1- BLTouchor V1.1.1- BLTouch. The easiest way is to try the latest version. If that does not work, then repeat the firmware install with V1.1.1. (V1.1.1 is the version that worked for our Ender 3 V2.) Is BLTouch working? For the BLTouch solenoid current conduction time, the time necessary for the detection pin to reach the desired deploy or stow position, that is, about 100ms, is sufficient, and no current is required to maintain the position of the detection pin thereafter.
