marlin 1.1.0 rc7 and inductor sensor 12vdc
May 09, 2017 04:00PM
hello , i just finished my 3d printer MPCNC version and since i have a large hot bed i need it a sensor to auto level the platform. well i can't figure out what i am doing wrong with Marlin firmware. try different version with same problem. i use repetier-host and on command M119 i see :
probe plug it to S+ of Z_min
x_min y_min Triggered at home position
z_min triggered
z probe open , i try to manualy trigger the probe led turn on but the repetier-host say still open ??? so if i try to send home the hot-end will crash on the platform bed.
i also now i get an error A probe needs a pin (Z_min_probe_uses_Z_min_endstop_pin || has_Z_probe
i will add the config.h
thank you for all the help

Need a bit more info pls
what controller board ?
what probe ?
how is the probe connected ?

looking at your endstop settings above, you have all endstop pullup resistors disabled ?

hi Obewan, sorry i forgot , its a ramps1.4 i use pololu 8825 driver and inductive sensor its a LJ12A3-4-Z/BX 6-36v NPN , use two resistor to 10k 20k to lower voltage to 5v signal from sensor connected to the z_min (S+) of the Ramps1.4
sensor works when i get a peace metal close and voltage change from low to high 5v.
do i need to turn all on the pullup resistor ??

[drive.google.com] the green wire to the Z-min its from the probe
[drive.google.com]


finally got internet service, all mooring out-order till now

Your connections look good and using the resistor devider,you dont need the Z endstop resistor enabled but you will need to enable the X and Y min endstop pullups.

This is acting as a NC probe, so try setting
#define Z_MIN_PROBE_ENDSTOP_INVERTING false

ok, sorry for the mix up firmware with rc5 to rc 7, i post the wrong version of config.

the lcd screen its went blank, light up, wont show anything , i can move the axis with repetier-host, i press home-z and ther axis goes up and then down but it won't stop when i trigger with a metal plate to stop it.
The Arduino Mega256 board got bad or over heat ??? will test l8r , need to take apart to test voltage regulator on board.
i attach the right version of configuration.h version rc7

ok , i am back on. lcd works. i setup the wrong board on config.h i setup ramp_14EFB , i also setup the pin z_probe_pin to 18 pin18 its the z_min_pin do i need to disable the z_min_pin or not.

the z axis works when i press home but if i hit home all axis the X Y axis reset to 0 and then moves to center plate and z axis goes down with out stopping.
one more thing after the 2 and 3 time i try to home z now it wont stop anymore but the probe light its on when i get a metal close. i am lost whats wrong ???

ok, update firmware to 1.1.0.1 and works it. i try the old version rc 5 and rc 7 and work too. here my mistake i did.
my sensor its npn no 6v-36v and a ramps 1.4 board.
first mix up firmware board from 13efb to 14efb
powering the sensor with a separate power supply.
i use a 1n4001 diode to send signal to the arduino, the resistor didn't not work , i use the wrong K-hom my reading was 3.9v high to 0 low
what i changed on the firmware: this its firmware 1.1.0.1 below
