Who it fits
Good fit for
You should buy this if you own a Creality Ender 3, V2, Pro, Ender 5, or CR-10 series printer. It is ideal for users who want to automate bed leveling without complex hardware changes. The kit fits well if you have a 32-bit V4.2.2 or V4.2.7 motherboard. You will appreciate the simple structure and the included brackets. It suits those printing on different bed surfaces like PEI or glass. The auto Z-axis compensation helps you achieve stable prints with less manual adjustment.
Who should skip it
You should skip this if you have an Ender 5 Plus with an SKR Mini E3 V3 motherboard, as the kit does not fit. It is also not suitable if you cannot update your printer’s firmware via SD card. You must remove the existing Z-axis limit switch to install it. If you do not have the correct motherboard version for your specific Ender 3 V2, the upgrade will not work. Check your motherboard version carefully before purchasing. This kit is not a universal solution for all 3D printers.
Verdict: This sensor kit is a practical upgrade for compatible Creality printers. It automates bed leveling and improves print stability.
Key specs explained
Color: Black
The sensor housing is black, matching most standard 3D printer frames. This helps the device blend into your machine rather than standing out visually. You get a cohesive look without needing paint or covers. If you prefer matching components, this color fits typical black extrusions. It does not affect performance, only aesthetics.
Width: 1.61 inches
The unit is 1.61 inches wide, making it compact for most printer gantries. You need to check your Z-axis limit switch space before buying. This width allows it to fit on standard Ender 3 and CR-10 models. Smaller printers might find it tight. Compare this width to your current switch slot to ensure physical compatibility.
Height: 3.93 inches
At 3.93 inches tall, the sensor extends upward from the mount. You must verify there is enough clearance above your nozzle to avoid hitting the print bed or model. Taller objects might collide with the sensor during printing. Measure your current Z-limit switch height to see if this vertical space works for your specific printer frame.
Length: 2.48 inches
The device is 2.48 inches long, defining its footprint along the axis. This length determines how far it reaches toward the bed center. You need to adjust your firmware coordinates to match this depth. Compare this to your current switch length to ensure the probe tip aligns correctly with the nozzle position for accurate leveling.
Weight: 4.23 ounces
Weighing 4.23 ounces, the sensor adds minimal mass to your moving axis. This light weight helps maintain print speed and accuracy without straining the stepper motor. Heavier probes can cause vibration or layer shifts. This weight is suitable for direct drive setups. Check if your printer handles this extra load on the Z-axis without issues.
Design and Build Quality
According to the listing, the sensor housing is black, matching most standard 3D printer frames. This helps the device blend into your machine rather than standing out visually. You get a cohesive look without needing paint or covers. If you prefer matching components, this simple finish reduces visual clutter on your workbench. The unit measures 1.61 inches wide, 3.93 inches high, and 2.48 inches long. These dimensions are compact enough to fit near the nozzle on most Ender and CR series models. The weight is 4.23 ounces, keeping the moving part light for fast Z-axis movement.
The kit includes a metal push pin, which the listing states allows for longer service life. This design choice supports multi-point detection on the printing platform. The sensor records the height of each detection point to stabilize your prints. You can reuse the mechanism more than 100,000 times, which suggests durability for regular users. The simple structure makes it convenient to connect for automatic Z-axis compensation.
Installation requires selecting a mounting bracket from the three provided options. You must remove the existing Z-axis limit switch and update the firmware via an SD card. This setup process ensures the sensor works with your specific motherboard version. The design supports PEI, sticker, glass, or metal beds. This wide compatibility means you can upgrade various surfaces without changing the core leveling mechanism. The layout prioritizes function over fancy aesthetics, focusing on reliable height detection.
Setup And Daily Use Guide
Setting up this sensor requires specific steps before you can print. You must select a mounting bracket that matches your printer model. Then, you remove the existing Z-axis limit switch. The next step involves downloading the correct firmware from the Creality official website. You must check your motherboard version to ensure you get the right file. Copy the firmware to an SD card and insert it into the printer. Power on the device to update the firmware automatically. This process is critical for proper function.
Daily use relies on automatic Z-axis compensation. The sensor performs multi-point detection on the printing platform. It records the height of each point to stabilize your prints. This works with various bed surfaces, including PEI, stickers, glass, and metal. The metal push pin design supports long service life. The listing states it can be reused more than 100,000 times. This durability helps maintain precision over time.
Compatibility is specific. The kit fits Ender 3, Ender 3 V2, Ender 3 Pro, Ender 5, Ender 5s, and Ender 5 Pro. It also works with CR-10 printers. Note that the Ender 3 V2 upgrade only fits mainboards with version 32-bit V4.2.2 or V4.2.7. It does not fit SKR Mini E3 V3 on Ender 5 Plus. You need three different mounting brackets for installation. The simple structure allows for convenient connection. You get stable quality and high precision for your printing tasks.
Compatibility And Setup Notes
You need to verify your motherboard version before purchasing. This kit only works with 32-bit V4.2.2 or V4.2.7 mainboards on the Ender 3 V2. Check your printer model against the compatible list, which includes the Ender 3, Ender 3 Pro, Ender 5, and CR-10 series. The sensor does not fit the SKR Mini E3 V3 on the Ender 5 Plus. You must download the correct firmware from the official Creality website and copy it to an SD card. This step is critical for proper operation. The metal push pin design allows for over 100,000 uses, reducing long-term wear. It works with PEI, sticker, glass, or metal beds. You will need to select the right mounting bracket from the three included options. This upgrade fits well alongside other bed leveling tools in 1 options. It offers a reliable mechanical solution for printers lacking auto-leveling. Ensure you have a working SD card and the correct firmware file ready before installation.
Check before you buy
- Verify your motherboard is 32-bit V4.2.2 or V4.2.7
- Confirm your printer model is on the compatible list
- Download the correct firmware for your specific printer
- Select the appropriate mounting bracket for your frame
