[FR]BL Touch and Z-Endstops #18

Closed Rich990 closed 4 years ago

hi, I am new here and just have a question but couldn’t find the right spot or button to post it, so I did it this way. With your latest version of Firmware WITH the use of BL Touch, what does the anycubic i3 Mega S uses for Homing? Does it used the Z-Endstops for that and the Bl Touch just for the ABL? Thanks for your help and answer!

I just successfully installed the BL Touch with the steps described in wiki/Installation-BLTouch. The Anycubic i3 Mega is using individual Z min endstops for both Z axis (left and right one) to synchronize them. With this firmware, both Z axis endstops are still working properly. By connecting the white/black pin to the X-carriage PCB as shown in the linked image, you are connecting it to a X-max endstop pin on your mainboard which you configure to act as your BL-Touch probe.

So, you are still using both Z-axis min endstops AND the BL Touch. The Mega-S should work the same way, but may require some minor config changes for the extruder. Haven't updated my non-S, yet :D

Note: I am using a BL-Touch clone, which has its pins swapped on the 3-pin connector. Watch your probe's manual and swap them if needed.
