ATTENTION: Creality BL Touch Application Notice

@daviesj
Thanks for the concern. The machine has been used for less than 12 hours. It's been out of the box for a week. There is some dust on the machine now from some CNC routing without enough suction at the dust shoe. I need to give it a good vacuum before I use it again.

@frated It looks like you have something wrong with your x-axis. The wear on your guide wheels is very excessive. You might want to check on why they are wearing so badly and also replace those wheels for smoother operation.

@jiva The BL-Touch is a replacement for your z-limit switch. You should unplug the z-limit switch once you install the BL-Touch. I removed the original z-limit switch completely from my Ender 3 V2 after I installed the BL-Touch.

Dear @jiva
Yes, you are right. Please unplug the Z-limit.
-
@admin If we are using the 5-pin connector, would we need to unplug the Z-limit connector?

@frated
BLTouch v1 mount on Ender 3 v2
- Take the screw out of the heater assy housing in back as shown.
- mount the BLTouch with mount without that screw
- use a scribe, nail, something sharp...to scribe the mount where the screw hole is
- drill the hole that you marked.
- reassemble with the new screw through the mount and into the housing as shown.

Dear @dkfauth
If your bltouch interface is 5-pin, it needs to be directly connected to the BLtouch reserved interface. If your bltouch interface is 3-pin and 2-pin, please refer to the video to connect

CLEAR AS MUD.

@dkfauth I just installed the Creality BL touch kit v1 on my new Ender 3 v2. The wiring guide showing the 3pin dupont and 2pin XHF connector jammed into the BL touch XHF port on the board is correct. I cut the connectors off and put a proper 5pin XHF connector on because I had an extra around. A couple of observations:
- The wiring locations are correct.
- The Z limit-switch does not need to be disconnected.
- The v1.1.1 firmware works https://forum.creality.com/assets/uploads/files/1598411525642-ender-3-v2-marlin-2.0.1-v1.1.1-bltouch.bin
- The updated v1.3.1 firmware did not work (though I may try again now that the v1.1.1 is working)
- The hole closest to the heating block is not in the correct location for the v2. I mounted it for placement, scribed through the screw hole and drilled a new one without much difficulty. The mount is soft metal.
At some point, I may revise my setup and do it with a proper kit. But, for a beginner with a center-low glass bed, this has solved my first layer problems.

@admin Your video https://youtu.be/HhrKBajQ5LA shows and Ender 3 v2 connecting the BlTouch with an adapter and z port and not using the bltouch port highlighted with the arrow. This should not be needed on the Ender 3 v2.
Your instructions here https://bit.ly/32zWVNt show connection directly to the bltouch port which is conflicting with the video. Which is it.
-
@admin I believe @dkfauth is talking about this port/connector (see red box):
Guides on the internet say to use this dedicated port with the BLTouch/3DTouch. Why do we need to use an adapter board instead of using this dedicated connector?
-
@DNW
To install bl touch, you need to unplug the Z limit line, please refer to the installation tutorial:
https://youtu.be/UOAMv3Hr7WcUntil now, We don't have a firmware that you don't need to unplug the Z limit line.
-
Dear @dkfauth, I am confused about the dedicated port, what it means? Please give more details, thank you.
-
@admin please respond back to my question on adapter boards and dedicated port. I am running on the dedicated port. Are you saying you are not supporting the dedicated port?
-
@admin Thanks for the info! So there won't be a Firmware for using the dedicated socket on the bord without unplugging the z-stop switch?
-
@DNW Dear, V4.2.7-this is for the users who change the mainboard, then need to upgrade. And another one is for the original machine that has any changes.
-
@SlackHacky Dear, could you please send more details about the issues?
-
@ocariduc, no, it just for the BL touch use. Thank you.
-
@ocariduc Dear, it is in the download platform. I have checked. Thank you.
