The first thing to do with the sensor is to mount it to the mounting bracket for your printer. Servo extensions as an alternative to the Creality Kit Cable We'll talk about custom wiring a bit later in this guide. You just have to double check that the pin assingment from the bltouch or 3d touch corresponds to the mainboard pinout. Here, we're using the original Creality BLTouch Kit for the Ender 3 v2, which comes with the corresponding holding bracket and the right cable for the Creality 4.2.X mainboard, which makes installation even more convenient.īut still, if you're getting the standalone version of the BLTouch, a pair of cheap servo extension cables and some dupont connectors will do the job equally well. All of them will give you reasonable quality results. Depending on if you buy the original BLTouch, which costs around 35-40 USD or a clone version like the 3D Touch or similar ones, which cost around 15-20 USD, this might be a more or less expensive upgrade. The BLTouch uses a deployable pin to measure a point of contact in the bed leveling process. It makes even more sense as this won't be in the exact same position every time you take it off and put it back on. That's why using a probe is the better solution in my opinion, resulting in a much faster and way better automated process - it's also going to be more consistent with different kinds of surface types and if you're going for a removable magnetic build plate, which I really like. However both methods bring along a lot more time investment to tune in the right distance in every measured position and swapping out the print surface because you like to print a different kind of material or need a different kind of adhesive will make you re-do the whole mesh bed leveling. Solutions for this issue are either using mesh bed leveling or the more advanced unified bed leveling if you don't want to invest in a leveling probe.

The glass plate that comes with this printer model is usually quite flat but if there happens to be a slight difference between the corners of the print area and the center, then you might want to compensate those differences for a perfect result. However, there is multiple factors that account for your success in getting a nice first layer printed and one is how flat the underlying surface is. The Ender 3 v2 usually is a pretty reliable printer in terms of print quality and you'll also find it not too difficult to get the first print layer down to the glass bed. Let's get started with some words about why you probably want to do this modification to your printer.
HEMERA ENDER 3 V2 UPGRADE
The BLTouch upgrade is going to work with both the 4.2.2 or 4.2.7 mainboard that you might also find in the Ender 3 v2, it's just going to be a minor difference in the firmware selection, you'll see that later. In this guide, we're installing the BLTouch Bed Leveling Probe on the Ender 3 v2. When the bootloader is done burning, carefully disconnect the jumper wires from your Ender 3, secure the control box cover, and unplug the Arduino from your computer.Daniel Crosslink, welcome back to the channel.
HEMERA ENDER 3 V2 MAC
If you're using a Mac, don't forget to follow the Mac setup instructions for the TH3D Arduino IDE.Īvrdude: stk500_getparm(): (a) protocol error, expect=0x14, resp=0x14Īvrdude: stk500_getparm(): (a) protocol error, expect=0x14, resp=0x01Īvrdude: stk500_initialize(): (a) protocol error, expect=0x14, resp=0x10ĭouble check connections and try again, or use -F to overrideĪvrdude: stk500_disable(): unknown response=0x12 Then, select Sanguino (1284P Boards) as the board. If you see an error such as the one below (especially if you're running macOS), try installing the TH3D United Firmware Package and running the included preconfigured Arduino IDE instead of the normal Arduino IDE.
HEMERA ENDER 3 V2 WINDOWS
Make sure you downloaded the Arduino IDE directly from the Arduino website (not the Windows store).Swap out your jumper wires in case yours are defective.Double-check your settings and connections.

If you run into issues, try the following: When the process is finished, you'll see a message stating "Output bootloader burned successfully". Then, change the Programmer from AVRISP mkII to Arduino as ISP. Select the Sanguino board from the Tools menu.
