BL Touch

Alright since I want to have the least amount of down time and to get it right the first time, is there a more updated tutorial for installing the BL touch?
I see this one (https://jgaurorawiki.com/a5/modifications/bltouch) but it states that 1.1.8 is not for that guide. And there is a lot of other tuts out there but they do not state what their firmware it. I tried 1.1.9 the first time but there were of course issues that resolved itself when i went to 1.1.8
Currently printing the bracket

Read the firmware text, its not so hard to fill in the right valves.
And check 1000times the wireing. Wrong wireing cause a defect BLtouch.
Check also the BLtouch homepage, there is also information about the BLtouch and the MKS board.
Mod of the mod tip, the black diamond plate is not even, its a grid. The BLtouch tip is sharp. If you want the perfect accuracy and little more heat resistance, you can use a metal 2k glue like the "innotec metal weld" to form a little flat tip. On the foto you can see that a little bit. The flat tip should be about 3mm in diameter. That adds nearly no weight to the tip of the BLtouch and is no problem at all, it will never fall down because of it.
After doing that you can lie a sandpaper on the heat bed, lower the BLtouch so that its pushing with the made flat tip and the spring (dont do that with the tip inside, it has to be outside) on the sandpaper and move the sandpaper even circular to grind it to the hotbed that its 100% even with the bed. Now the flat tip and the heatbed fit perfect together and the gridy surface is no problem.
Good luck with your BLtouch, its a realy great update! I recommend to level the bed as good at it gets and measure the high of every spring high. Now you can make a heat resistand distance (bakelit or carbon diam. 10mm, 3mm hole) with the exact length and change the springs against it. The plate will be more stiff, no wobbling any more.
In time i will try to "upgrade" the tip with a new tip with mods. I have to finish printing some things so getting this on there and printing again is important. little down time right now.

Yeah XD next week we fly to the moon with the JG
The tip you cant print with any filament. The problem is that the heat plate can deliver 110°C so the glas temp of the filament would had to be the same. I dont know any seriouse filament (maybe clapton) that has realy such a high glas temp. most filament producer say that they can get so high but the truth is different.
Try the BLtouch holder like I have, its great. Only modded it a little with a dremel to get it a little higher.
Alright so the next issue is that by default the place i put the black and white cord is taken. Again after a search no one else seems to have this issue... fun me. At least the section where I put the other cord is open.
I see from your above picture that it gets attached to the carriage on the front. Do i need to get longer screws? What type would i need to get. Also what would your offset settings be. looks like i might not have a choice on doing it your way.
You mean the Z micro swich cable? Yes you have to remove it. The BLtouch does that job then.
Offset is something like -2.15 ir something but i would beginn with 0 and go lower just to have no crash.
I will but this thing back together and print your mount. then maybe get it on today to resume printing
Unplug everything and check 1000 times if you made the job propperly. Than you are save.

Yeah thats always a problem when you work on the printer and see ups I need a new correct print. Happened to me today, my redesigned cold fan mount was wrong... I hate mod. prints from thingiverse.... they are all crap! Better to design something own...
But i followed the code update on the video and have run into a error verifying the code and even the git doesnt help here. remember 1.1.8.
#error "LCD_BED_LEVELING requires MESH_BED_LEVELING or ABL with PROBE_MANUALLY."
On another note did you design the stl's above? i would see if you could upload the thingi as its pretty good.
comment out the LCD_BED_LEVELING to get rid of that error. Verifies. Lets hope for the best
Edit: when using g28 or the home on the screen the pin does not extend at all. There must be something missing. there is no errors on screen
Update 2: since the pin is not moving I followed the directions on the wiki to find out what the servo port is. I confirmed that it extends on P1 but even with this info I do not understand what to do with this info
If the nozzle is slamming into the bed and the BLTouch is not deploying the pin to Z home/detect you might need to reconfirm your servo port (see above) and then change the servo port number (which starts from zero) to match the P<port number> number.<br>What do i need to change on the config file.
Btw i am leaving all items here in case someone else comes across this info and needs to figure this out.
#define Z_ENDSTOP_SERVO_NR 1
So basically the port you test the extending and retracting with is for the above. Also note, which is important, if the red light is on but the blue light on the bl touch is not then something is wrong
I am still doing research to find out how to do this. but if anyone can help it would be great.
EDIT: what is not stated on that video, and i didnt find it elsewhere, is that for the jgaurora needs to have the below enabled. Since homing is off the build plate.
#define Z_SAFE_HOMING
I didnt had that problems, maybe you missed something from the video?
You can use a pack of tempos to check the function of the bltouch the first time.
I used after that my phone case, its leather and dont destroy the nozzle or the bed.
Howdy, Stranger!
