BLTouch搭載機メンテナンスの仕方
Sinich.iconBLTouchの許容範囲を超えるゆがみが発生している場合、オフセット設定をやり直す必要が出てくると思います。
以下の通り3Ⅾプリンターの操作を行って下さい。
Calibrate the Z Offset for the BLTouch Probe
The updated printer firmware will allow you to set the Z offset, which controls the position that the printer considers to be “0” directly on the print bed.
Follow these steps to calibrate the offset:
1. Auto home the 3D printer.
2. Select Control » Initialize EEPROM.
3. Place a sheet of paper under the nozzle, then move the Z position (Prepare » Move Axis » Move Z) until you can feel resistance on the paper but you can still move it. Write down the ending value (it may be negative).
4. Navigate to Control » Motion » Z Offset. Adjust the value by the recorded amount (for example, if the recorded value is -.4, adjust the value to be .4 less than the current value. If the current offset is 0, just set it to -.4).
5. Under Control, select Store Settings to save the offset.
6. Power the printer off and back on, then auto home the printer, and verify that the nozzle is positioned correctly.
7. In the same menu, select Disable Stepper to unlock the motors, and repeat the leveling process at each corner (just like standard leveling).
1. Move the nozzle to a corner of the bed.
2. Place your sheet of paper and adjust the leveling knob until you feel some resistance when moving the paper.
3. Repeat on each corner.
8. Now that the bed is level, fine tune your Z offset by repeating steps 3-5.
9. Replace the Gcode “G28” in your slicer’s starting script with “G28 G29” to run mesh bed leveling before each print.
You are now ready to run a test print! We recommend testing with a model that has a large footprint to make sure the leveling is correct. If you notice that the first layer is too high or too low, you can “live adjust” the Z offset in the Tune menu if you notice that the first layer of your test print is too high or too low. Any changes you make here will persist for future prints as well.
