In the early version of this component, the cable is soldered to the endstop terminals, but in the current version, the cable and the endstop can easily be separated, making the exchange of the component easier.
If you have the original version or want to change both the endstop and the cable continue to Change Z endstop+cable.
If you have the current one continue reading:
Change Z endstop.
1. To change the endstop turn off and disconnect the BCN3D Sigma.
x2 M2.5 10mm
3. Once the screws have been removed, detach the cable from the endstop terminals and connect the new endstop, paying attention to the original connection of the cables.
Warning! Before removing the cable from the endstop terminals, pay attention to the positioning of the cables in order to connect these properly on the new endstop.
If you are having issues accessing the endstop screws you can remove the X-axis belt to have better access to the screws.
Change Z endstop + cable.
1. Turn off the printer and unplug it.
Note: If your hotend has a tie-wrap holding the cable to the printing head, make sure that you cut it before removing the hotend and install a new one when you complete the change.
6. Disconnect the endstop cable from the extruder board.
8. Connect it to the extruder board, and screw it to the printing head.
If you are having issues accessing the endstop screws you can remove the X-axis belt to have better access. To remove it, pull down the belt that is connected to the printing head where you want to change the endstop.
Once the new endstop is installed, assemble everything back as it was, and make sure that the endstop is working correctly by performing a bed calibration.
