How to use an Inductive Sensor with a MKS SBase/Ramps/All boards

Just as requested, here's how to set up an inductive sensor on just about any board.

Things to note:
Your sensor my work at 5v so check reviews before you buy.

remember there's 10k resistor in the probe so a single resistor is needed for a divider.

I'm using a NPN capacitive sensor straight into my Mks ( 12v and Z min pin) and having awesome results, both with aluminum and glass over it.

WOULD you be able to make a video ideally along the same overall formula but for a TWO wire nc proximity sensor please...?

thanks i didnt think it would be this easy, You rock man

Curious if you measured your logic hi when sensor is plugged into MKS Sbase. I'm seeing 3.7V high with a 10K from Signal to Gnd. I would expect 10K/(10K+10K) * 12V = 6V with an NPN inductive probe that has internal 10K pullup and is powered by 12V. I also measured 1.2 Kohm between signal and grnd of end limit connector on MKS Sbase board with no power and no switch or inductive probe attached. Was the same for all end limit connectors. 1.2K/(10K+1.2K) * 12V = 1.28V which is not 3.7V. This also has me confused. I'm aware 6V will damage the controller but since there is something pulling down to 3.7V as well as it functionally works I believe their might be some sort of protection circuitry on the MKS board that pulls on the logic level.

Thank you guy, you just saved me a lot of time

Thanks, many useful tips in your channel, keep this good work.

Hi i no this video is from a few year ago but how did you wire up the probe ie 12v + and - from power supply and signal to the board I am cunfused how you wired the probe up please help

[JustinJJHCS]

is that a PNP probe? I am having trouble getting it to work... is it because it is working off the 5V from the endstop plug or do you need to connect it to 12 VDC....

Could you help me understand?
The bltouch has 3 wires that go to the servo and 2 that go to the endstop -Z, where the inductive sensor uses only one signal wire that goes to the endstop -Z as well.
Why does the BLtouch need to power on the servo and the inductive does not?
You could also use the voltage regulator
7805.
Powering the sensor with 12 volts and the sensor only output entering a resistor in the regulator and use the regulator output as signal.

umm interesting, but can you sharew configurations for MKS Robin Nano with version 2.0.3.2 = thanks in advance !

[solidus]

Did you have to use a seperate endstop for homing the z axis just changed from a ramps and having trouble figuring out the smoothieware setup

Hello!

My sensor is an SN104-N. It is working with the original board.
On my MKS Gen L it doesn't trigger, but the LED is alight, when I put metal below.

I tried soldering this resistor, but it didn't help for me. I measured 50k Ohm from black to blue without any power connected, as I don't have tne cables or a power supply for doing this.
Do I need to have power supplied to the sensor when measuring this resistance?

[derivas]

you really do a tutto for endfilament sensor it will be great

look at aliexpress they sell some

[derivas]

great tutto
could you make an another for end filament sensor?

[ajc]

The same process for a capacitive sensor?

[aeroms]

hi Bryce, thanks for the video. I'm trying to make my Hypercube working with MKS Sbase + BLTouch, but not getting anywhere. I was thinking to give a it try and use inductive sensor I have. Can you please share with me your config file, either BLTouch or inductive configured one. Would really appreciate it. thanks

Hi Guy,

i need to use the smoothieboard v1 to control 3 steps motor, 3 endswitch and 3 servo motor. But i never used before. can you tell me please how to connect it to the computer or how to use it? Do i need another sofware or microcontroller to control the Board? what are the differents steps till i run the first programm please?

Kind regards

[derivas]

where we need to plug pt100 sensor on this board?

[lIPuntolI]

Any idea why my no matter doesnt work.
