• An error in the Z centre deviation shows up as poor hole-to-hole accuracy between the left and right faces.
  Original record

  中心偏差Z有误差，会反应在左右两面的对穿孔精度上。

• For that pattern, add 1 mm to the X centre deviation in the tube software's manual or automatic centring.
  Original record

  图示情况，须在TubePro软件/手动定中或自动寻中里，中心偏差X里增加1毫米

• Badly deformed tube cannot be cut normally — replace the tube rather than compensating in the software.
  Original record

  形变严重的管材将无法进行正常加工，需更换管材。

• When calibrating, check that the tube used is a standard rectangular tube with no chamfer.
  Original record

  检查标定所用管材是否为没有倒角的标准矩形管

• With the B-axis centre correct, the same pattern appears when the tube and the chuck are not concentric, or when the automatic centring offset is wrong.
  Original record

  在B轴中心是正确的前提条件下，如果管材和卡盘不是同心的，或者自动寻中的偏差不对，会出现图示情况

• If the tube is clamped at too great an angle to horizontal, single-face levelling cannot succeed and the software reports a levelling failure.
  Original record

  在实际装夹管材时，如果待切管材与水平面的偏转角度过大，在进行单面矫平时便会无法矫正成功，软件提示矫平失败。

• When single-face levelling fails, first check that the levelling face really is a plane — only a plane can be levelled.
  Original record

  在对待切管材进行单面矫平时，当软件出现矫平失败的报错提示后，首先检查矫平面是否为平面，只有平面才能进行单面矫平。

• If levelling still fails after returning to origin, check whether the levelling face is angled off by too much.
  Original record

  回过原点后单面矫平依然失败，需要排查矫平面是否偏移角度过大。

• An inaccurate axis coordinate system makes the reference coordinate used during levelling wrong, which is what makes levelling fail.
  Original record

  如果轴的坐标系不准确，便会导致矫平过程中进行比较的基准坐标值不准从而造成矫平失败。

• When Z following is stable and accurate but calibration still reports a tube size error, this is beyond field adjustment — raise it with service.
  Original record

  当Z轴跟随稳定性和准确性都正常但标定时依然提示管材尺寸错误，则联系柏楚技术服务人员。

• Seven-axis pulling reports the remaining tube is too short to cut — check the remnant length and the material feed position.
  Original record

  七轴拉料时提示剩余管材过短，无法切

• With the chuck clamped, Y and B cannot home independently — release before homing.
  Original record

  处于夹紧状态Y/B无法独立回原点

• Tube with a weld seam: use the seam-avoidance function so the seam does not land on the cut.
  Original record

  管材上有焊缝，如何避让焊缝切割

• Adding process to the slot on a round tube's cut-off line.
  Original record

  圆管切断线上的槽口添加响惯孔工艺

• If neither condition is met, the tube and the drawing do not correspond — fix the drawing with the hole-offset function.
  Original record

  如果不满足以上两条件，可以认为管材和图不致，建议通过孔的偏移功能来修图。

• How to read the TubePro fault log — always pull it before diagnosing a tube-side alarm.
  Original record

  如何读取TubePro故障信息日志

• Check that the descent-in-position signal triggers, that the support bracket is not jammed, that the switch is not damaged and the wiring is intact.
  Original record

  检查下降到位信号是否正常触发，支架是否卡住，到位开关是否损坏，线路是否断开。

• Full-travel three-chuck homing reports the height controller is not in position — check the controller state before homing.
  Original record

  全行程三卡盘回原点提示调高器不处于

• Set the correct camera brand in the platform configuration — a wrong brand leaves the live view blank.
  Original record

  注意平台配置里面的相机品牌要设置对

• Dahua cameras need the stream encoding mode set to H264H before the monitoring picture displays correctly.
  Original record

  例如大华相机，需要在视频码流里面的编码模式设置为H264H，软件里面才能正常显示相机监控画面，注意

• When looking up tube dimensions, always confirm the nominal size and the fit type — the same nominal size comes in several fits.
  Original record

  注意：查询时请务必确认基本尺寸和配合类型。

• Centring a non-standard tube profile: the approach differs from round and square tube and needs its own routine.
  Original record

  异型管寻中方式总结

• Drawing bevel cuts on I-beam — the profile needs the bevel built into the geometry, not applied as a process.
