Trouble configuring 3d touch z probe
December 15, 2018 08:02PM
G'day everyone,
first of all great forums, lots of good information around here. Plenty of which has come in handy in the past.

Im having some trouble trying to setup my new z probe.
I have purchased a 3d touch z probe and have plugged the 2 pin connector into the zmin, and the 3 pin connector into the zmax.
The trouble i have is when i try and configure marlin.

under z probe options in configuration.h i have
#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN

then if i enable either bltouch or both of
//#define Z_PROBE_SERVO_NR 0 // Defaults to SERVO 0 connector.
//#define Z_SERVO_ANGLES {70,0} // Z Servo Deploy and Stow angles

when i try to verify i recieve the same error:
"servo0_pin must be defined for your servo or bltouch"

however i cannot find where to define the pin for servo 0.
cannot find anything to do with servo in pins.h or pins_minirambo.h.

i have enabled num_servos 1 in configuration.h but this is the only servo related line i can find.
when i go onto the 3d touch wiki page, i still cannot find the specific lines they are after anywhere in my marlin config.

I am fairly new with marlin but hoping someone could lend a hand,

Thanks.

Jim.

Thank you very much mate,
good to see a guide on someone else using the same board.
Im still having trouble with one thing:

// Faux Servo for BLTouch
//
#define SERVO0_PIN 10 // ZMin pin used as PWM pin for BLTouch. Only MinEndstop pins can be used for PWM. - JWG

i am unable to find that define servo line anywhere...
i have searched for "servo" in configuration, pins, pin_minirambo
but still cannot find anything similar ?

I have now added the define servo line myself, and it compiled. so step closer thank you very much

After a bit of fiddling around i have got the probe to go in and out 3 times on startup, it also follows commands such as, retract, extend, reset fault mode. however the zmin endstop shows as open, and also shows as open after i touch the probe when extended. also when i home z the carriage moves up slightly and then down, however when i operate the probe with my finger it does not stop moving ? 2 pin wires from probe are connected to ground and signal of zmax

You have to connect the 2 pins of 3d touch to GND and Sig on Zmin...
