Kossel Delta Z axis 3D Printer High Precision Z-Probe Auto Bed Leveling Sensor kit 3D Touch Sensor for V6 nozzles and MK8 nozzles Hotend

The Kossel Delta Z axis 3D Printer High Precision Z-Probe Auto Bed Leveling Sensor kit 3D Touch Sensor appears to be a cost-effective option for automatic bed leveling in 3D printers. However, there are mixed reviews regarding its performance and usability. Some customers found that once properly wired up, the sensor is very accurate and works well. It eliminates the need to worry about XY offsets and most of the time doesn't require a Z offset. It is also compatible with Marlin UBL and produces great first layers. Additionally, the sensor is affordable, making it a good value for money. However, there are several issues that customers have raised. Firstly, the product comes with no instructions, and the product photos do not represent installation on all printers, causing confusion during setup. Secondly, the included foam is designed for V6 nozzles and not suitable for MK8 nozzles, making it harder to attach. Some users reported that the sensor falls off occasionally, resulting in the printer ramming into the bed. Moreover, the sensor's design as a physical button that attaches to the nozzle creates problems. It requires manual placement for homing and leveling, and users need to remember to remove it before heating the hot end. The force required to trigger the sensor can lead to the extruder already smashing into the bed by about 1mm, although this can be adjusted with a Z offset. Additionally, the readings from this sensor are not as Consistent as other types due to movement shifting the pad during homing or leveling. Overall, the Kossel Delta Z axis 3D Printer High Precision Z-Probe Auto Bed Leveling Sensor kit 3D Touch Sensor is a good concept but has several drawbacks, including attachment issues, inConsistent readings, and the need for manual handling. Some customers recommended investing in alternatives like the BLTouch or Pinda probe to avoid headaches in the long run.
