• Manual nesting reports not enough parts — check the sheet size and the part quantity actually selected.

  怎么解决手动排样，提示零件数量不够的问题

• Piercing count comes out as 0 — the pierce point is not being registered, usually a layer or process setting.

• Not all parts got nested — check the remaining space and the nesting timeout rather than the part count.
  Original record

  怎么解决零件未全部排完的问题

• A part contains a broken contour — close or repair the geometry before it reaches the machine; it will not cut cleanly otherwise.

• Import failed or was recognised wrongly — usually a DXF entity type the software does not map, not a corrupt file.

  怎么设置引线固定从某个方向引入

• How to make micro-joints apply to a shared-edge group — the joint has to be set on the group, not on each part.

• Does weld-seam compensation change the finished part length — yes, and it has to be accounted for in the drawing.

  怎么导出每个排版结果一个文件

• Batch-setting process parameters after nesting — far faster than part by part.
  Original record

  怎么在零件排样后，批量设置工艺

• Check the cutting path after nesting: the order the software chose is what the machine will actually do.
  Original record

  怎么查看排样后的切割路径

• Setting process on inner contours only, or on the outer contour only.
  Original record

  如何只设置零件内轮廓或者轮廓工艺

• Setting the cutting direction of a part's outer contour — direction matters for heat build-up and dross.
  Original record

  如何设置零件外轮廓切割方向

• Splitting, measuring and bridging curves with a base point — the base point is what keeps the geometry closed.

• Piercing in one, two or three stages — each stage has its own height and dwell, and mismatched heights are a common cause of blowouts.
  Original record

  一、二、三阶段穿孔

• Typical three-stage piercing heights — use them as the starting baseline, then adjust from there.
  Original record

  通常三级穿孔高度

• Two-stage piercing heights for thinner material where three stages over-complicate the cycle time.
  Original record

  二级穿孔高度

• Piercing height set unreasonably — check this before blaming power or gas.
  Original record

  穿孔高度设置不合理

• Blowout during piercing — reduce the piercing duty cycle, increase negative focus, and check the pierce height.
  Original record

  穿孔过程中爆孔

• On high-power sources piercing blows out far more easily; the piercing ramp has to be re-tuned for the power level rather than reused from a lower-power machine.

• The two piercing modes — knowing which one the machine is in explains most blowout complaints.

• Lower the peak power — the first move when piercing blows out or the pierce hole is oversized.
  Original record

  降低峰值功率

• If the pierce is failing to break through, increase piercing power in 5% steps rather than jumping.
  Original record

  增加打孔功率，每次5%

• Use the power curve instead of a flat power setting — it is what keeps a contour consistent through corners.
  Original record

  使用功率曲线

• Optimise the corner dwell parameter — this is the single biggest lever on corner dross.
  Original record

  优化拐角延时参数

• Corner dwell time set unreasonably — too short leaves dross, too long burns the corner.
  Original record

  拐角停留时间参数不合理

• Reduce the corner feed rate moderately rather than slowing the whole contour.
  Original record

  适当降低拐角行进速度

• Change the cutting order — it is often the cheapest fix for heat distortion and tip-up.
  Original record

  改变切割顺序

• If the automatic order is poor, sort manually. When the toolpath runs Y ascending and the finished scrap lifts up, the head trips a collision alarm — change the cutting order and the problem goes away.
  Original record

  效果不理想，需要手动修改排序方式。如果遇到切割轨迹是按照Y从小到大，但是实际生产中出现切完的废料翘起来，容易报警切割头碰板，但是可以调整切割顺序去规避这个问题。

• Use speed mode where the machine supports it — it holds the feed rate through geometry changes better than power mode.
  Original record

  使用速度模式

• If speed mode is not supported on this configuration, the corner behaviour has to be solved with dwell and power curve instead.
  Original record

  不支持速度模式

• The tube corner process setting lifts the head by the configured amount at corners; it also helps when Z-axis rigidity cannot be improved further.
  Original record

  可开启管拐角工艺设定，设置

• That option raises the head by the set value at each corner, and is worth enabling when Z-axis rigidity cannot be increased any further.
  Original record

  会在切割拐角时会额外上抬设定值，同时，如果Z轴刚性已无法再提升，也可勾选

• Enable special edge-finding in the global parameters.
  Original record

  在全局参数里面启用特殊寻边

• On a bus system this is switched on from the global parameters rather than from the machine-side menu.
  Original record

  若系统为总线系统，可在全局参数中开启

• Edge-finding offset: a side distance difference of 2 means shifting the head right by 1, and right is X-positive, so the correction is X+1.
  Original record

  侧边距离差是2，需要将切割头右移1，右方向为X轴正方向，即为X+1

• Cutting-head collision detection — worth enabling on tube machines where tip-up is common.
  Original record

  切割头干涉检测

• Check that the speed gain matches the drive parameter; a mismatch shows up as position error rather than as an alarm.
