Collision prevention requires a combination of hardware settings and process optimization:
Precise follow-up height setting:
Adjust the sensing range of the capacitive sensor according to the material thickness (for example, a 5mm plate needs to be set to a height of 6-7mm), and verify the actual distance through the "Z-axis calibration" function.
Pre-processing calibration process:
Use the "edge finder" or camera vision system to locate the edge of the material and ensure that the cutting path is within the plate range.
Perform a three-dimensional scan of uneven materials (such as deformed metal plates) to generate a height compensation curve.
Equipment status monitoring:
Regularly check the sensitivity of the capacitive sensor (test the response time with a standard thickness block <0.1 second).
Replace worn nozzles (aperture deviation >0.2mm needs to be scrapped) to prevent scratching the material.
Emergency treatment: Stop the machine immediately after the collision, check whether the cutting head connecting rod is deformed, and measure the Z-axis verticality with a micrometer (error <0.02mm/m).
