Endstop z still triggered after retract

[MrGray942]

Manta M8P with HermitCrap V1 was working fine with microprobe V1.2. After the pin get damaged and replaced with microprobe V2 it keeps given the some error, "Endstop z still triggered after retract" the set up is okay and regardless any changes applied I still get the same error. Purchase the second probe and have the same situation. Is any solution for it. I have seen lots of similiar cases and no answer from bigtreetech. What is going on

same her I will try to connect a CR-Touch that I have and test

Dear People, I need your help.

I have installed the Biqu Micro Probe in a new Manta EZE3 with driver TMC5160 RGB ( I think also are PRO)

I have a double Z axis setup using the frame of my Ender 3.

After hours of research and reading similar issues as mine, I am not sure now where is coming the problem.

In the start of the journey to find the solution to this error: " Endstop Z still triggered after retract", and after trying with different options with changing position of the cables for the Z endstop following the instructions from BTT, changing the the printer.cfg settings following carefully the official instructions to make work the probe, I came to the conclusion that I am desperate.

Right now the Y,Z go homing but Z move a little bit down and then stops, is not homing. The probe is deploying in the air because Z is not homing. After hours of testing different settings with cable and .cfg, the system right now is not displaying anymore the error " Endstop Z still triggered after retract" but I can hear the Z motors in stall mode, and the Z motors go very hot if I leave it some minutes in this way. You will see in the .cfg file the pins are correctly set for the mainboard EZE3. I have checked 100 times the pin position and even play it with different pins positions using the Z endstop changing the pin in the settings, but the only change is that instead of going down the Z, is going up.

Maybe some of you have some idea how to set my mistake or probably I have a defect probe. I even tried with a CR touch that I have here, but didn't work correctly and I think I need to change the cable for the CR touch because I was using the original cable from the Biqu Probe.

same issue started today. the z will drop when homing then get endstop z still triggered after retract. also unable to deploy pin when commanded to anyone have a fix?

M8P w/cb1

Hi guys i am having the same problem with exact same harware. Just watched https://www.youtube.com/watch?v=q6ffmH99hRA this video and now i can move the pin down. But when i try to home the machine the pin goes down, head moves 2 cm up and than pin goes up and error shows.

[javcab2003]

share with me your printer.cfg I have resolved the issue. I just found the the way to setup the dir_pin with or without the ! symbol. But I need to see first your code and you need to explain me your printer, do you have double Z, ender 3? just to know. Also I have checked the cable from the probe to be perfectly installed and no loose cables

[jokhacker-maj]

Thanks man i just resolved it 1 hour after original post. It is exactly what you said. I forgot to put ! in front of the pin. Thaks, happy printing.

If you replaced the MicroProbe V1 with a V2 you need to invert the z Endstop pin on my manta m4p it's the following

[probe]
pin: ^!PC14 # ^PC14 for V1 Probe

[Kruworkz]

It's a v2 on a manta m8p

My problem with the biqu microprobe is a hardware one, i get the same error "Endstop z still triggered after retract" the pcb is loose and moving outside of the body of the probe, i push it back in with 1 cm and the error disappears. i think the probe pin hit the printed part too much and the pcb is loose because of that.
