 ====== Retrofitting the Anycubic I3 Mega with an ANTCLABS BLTouch leveller ======
@@ Line 4: / Line 6: @@
 The printer can be upgraded with an automatic leveller from [[https://www.antclabs.com/bltouch|ANTCLABS BLTouch]]. In the following overview it is shown how this upgrade is realized within the original design.
-After modifying hardware, also [[cura_bltouch_and_profile_settings|software needs to be modified]] in order to allow the 3d printer to recognize the leveller and use it accordingly.
-==== Hardware modification ====
 The pins with which the ANTCLABS BLTouch interfaces at the controller are D2 and D11. Although it would be possible to use other pins, it has become a kind of de facto standard for this printer to use these ones:
   * D2 (Mega 2560, digital pin 2) for Zmin (Note that this signal has the label +X on the controller circuit board)
   * D11 (Mega 2560, digital pin 11) for the control signal
-To understand how to connect the leveller to the controller, the following overview shows how the signals are routed (click on pictures for larger size):
+To understand how to connect the leveller to the controller, the following overview((The original version of this drawing showed a wrong path for the entry point of the D2 wire (large connector instead of middle connector, pin 5) at the I3-MEGA-HUB circuit board, and the continuation of this wire at the HUB circuit board (green wire, not yellow), as was pointed out on 02-07-2020 by Mr. Marco Burato. Current drawings show the correct routing.)) shows how the signals are routed (click on pictures for larger size):
