Real-time State Check Parameters

Out Margin Check

  • Whether to check the cutting head moving beyond the workpiece margin during following.
  • If the cutting head moves beyond the workpiece margin, it will stop.
  • Default value: Yes

Out Margin Tolerance

  • Compared with the follow-up height position, if the current position is beyond tolerance range, the system will consider the cutting head is beyond the workpiece margin.
  • Range: [0, 20]mm
  • Default value: 2

Out Margin Sensitivity

  • The larger the value is, the higher the tendency is to judge whether the cutting head is beyond the workpiece margin.
  • The larger the value is, the higher the tendency for judging out margin is.
  • Range: [1, 10]
  • Default value: 5

Speed Setting Parameters

Z-axis G00 Speed

  • Speed of the cutting head during moving up and down.
  • A too large value needs calibration length added accordingly for the cutting head to slow down, so as to avoid colliding with the workpiece.

Follow-up Outside Workpiece Parameters

  • Range: [0, 5]mm
  • Default value: 0

Reference Height in Margin

  • If current capacitance stays smaller than the capacitance corresponding to the value of this parameter during sense delay, the system considers the cutting head within the workpiece margin and automatically opens follow-up.
  • Range: [0, 5]mm
  • Default value: 0

Sense Delay in Margin

  • Needed delay time for detecting whether the cutting head is within the workpiece margin.
  • A too large large value leads to lag during following and a too small value leads to too sensitive response.

  • Default value: 5

Sense Delay Out Margin

  • Needed delay time for detecting whether the cutting head is beyond the workpiece margin.

  • Default value: 50
