Precise automatic leveling

The 3D Touch sensor uses the Hall effect to provide accurate bed leveling by detecting the surface points on the heated bed. It compensates for uneven platforms by adjusting the printer’s Z-axis height during printing, ensuring high-quality prints even on imperfect beds.

Firmware compatibility and setup

Compatible with Marlin firmware 1.1.X and later, this sensor requires specific configuration steps including connecting wires to designated pins, enabling BLTouch features, and setting the number of leveling points. Proper firmware adjustments prevent sensor damage and optimize performance.

  • Connect 3-pin wire to D11 and 2-pin to Zmin interface
  • Enable Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN and BLTouch leveling in firmware
  • Configure leveling method and number of probe points
  • Set nozzle deviation in XYZ for accurate probing
  • Enable EEPROM settings and save with M500 command

Versatile printer compatibility

Designed for various 3D printer models such as Reprap mk8, i3, Ender 3 Pro, Anet A8, and Tevo. Works with delta printers by assigning Zmin and Zmax pins appropriately, offering broad compatibility for hobbyists and professionals alike.

  • Supports Reprap mk8, i3 series, Ender 3 Pro
  • Compatible with Anet A8 and Tevo printers
  • Supports delta structures with correct pin configuration

Product FAQ

Frequently asked questions

01 What is the primary function of the 3D Touch sensor?

It uses the Hall effect to automatically level the 3D printer's build platform by detecting the bed surface and adjusting the Z-axis height during printing.

02 Which firmware is compatible with this auto bed leveling sensor?

It is designed to work with Marlin firmware, specifically version 1.1.X and later, with required firmware modifications.

03 How is the 3D Touch sensor connected to the printer?

The sensor connects via a 3-pin wire to D11 (positive and negative must be noted) and a 2-pin wire to Zmin for the Z-axis endstop.

04 Can this sensor be used on delta structure 3D printers?

Yes, on delta printers it can use the Zmin interface as the BLTouch sensor and use Zmax as the machine limit switch.

05 What must be enabled in Marlin firmware for the sensor to work properly?

BLTouch leveling must be enabled, along with 'Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN' and EEPROM_SETTINGS for saving leveling data.

06 How many leveling points can be set through firmware configuration?

Users can set the number of leveling points, for example, 5 by 5 points for a total of 25 measurement points.

07 What is required to prevent the sensor from touching the heated bed?

Enabling the zero return center setting causes the printer to move to the middle of the bed during homing to avoid sensor damage.

08 Does the sensor require any special handling or chemicals?

No, the product contains no high-concern chemicals and is safe to use as a new 3D printer module.

09 Is the 3D Touch sensor compatible with Ender 3 Pro and similar printers?

Yes, it supports Reprap mk8, i3 series, Ender 3 Pro, Anet A8, and Tevo-type 3D printers.

10 What additional firmware configuration is necessary to save leveling data?

Uncomment '#define EEPROM_SETTINGS' and use M500 command to save data so that leveling info persists after power off.

Everything matches the description, but the cable did not reach the basement of the Ender 5 Pro (my mistake, I used a short 1m cable).
