A10T and Vert's Marlin to enable 3d touch sensor

[bb1234567]

Hello!

I bought the geeetech A10T printer and have some troubles with it.
After downloading VS-Code with the necessary plugin, I have opened the code from github (B485) and did the
configuration as Vert described in his youtube video.
Afterwards I compiled the Source Code and uploaded the firmeware as he descriped in his video via octoprint (probably it is the easiest way).

After flashing the new firmware I installed the 3d-touch sensor. So far as good... now i tried the "z probing" and also to scan the bed level via octoprint but everytime the noozle crashes into the bed. The sensor to not halt and the printer and crashes...

How can i fix this problem? Is there anyone who has the same problems?
I already tried :
- switch the direction of the 3d-touch pins.

Hi, when updating the firmware with the 3d touch version,
Whether to calibrate it,

When 3d touch performs a self-test,
Whether the probe will expand or contract.

You can remove the limit switch on the z axis,
Because 3d touch also functions as a limit switch.

Thank you for your response. I have removed the limit switch.

How can i calibrate 3d-touch?
Marlin offers me in the configuration section different options for that:
- Reset
- Self-test
- ...

After pressing the reset, the red light of the 3d touch gets off.
After doing the self-test the 3d-touch pin gets in and out and the red light beginns to flashing.

Afterwards i started "Probe UBL":
When i doing this, the printer stops after the first touch. The 3d-Touch-Pin stays inside and the LCD-Screen shows me "Homing Failed: Printer HALTED"

Hi, you can refer to this:
Repetier Host, input the following commends and send them to test it one by one:
M280 P0 S10; pushes the pin down
M280 P0 S90; pulls the pin-up
M280 P0 S120; Self-test – keeps going until you do pin up/down or release alarm
M280 P0 S160 ; Release alarm
