Toolboard LC1 - IO1 failed?

Marshal

Hi all,

i ran into issues today with the IO1 of a tool board
It is not working anymore.

IO1 was configured for an optical end stop

M574 X1 S1 P"20.io1.in"

and it was working for quite some time.

As off today the sensors is showing as triggered when it is not.
When connecting the sensor to IO2 and changing the configuration accordingly, the sensor is working fine.

I checked the supply voltage on IO1, it is 3.3 V.
The optical end stop has one led which is lit up when the sensor is not triggered.
I tried to only connect V+ and GND, in this case the led is lit and triggers when triggering the sensor.

Maybe there is a short on the signal line? Can i check this somehow?

Without power

IO1.in to V+ is shorted on the tool board
IO2.in to V+ is not shorted on the tool board

Thx in advance.

The inputs on the toolboard are "Pulled-up" to 3.3 Volts and that is why you are reading 3.3 Volts on the pin when it's disconnected.

Try using a jumper to connect the IO pin to a ground pin and see if you can configure and read the state of the pin changing.

Also, is there something going wrong with your toolboard? (I'm unfamiliar with these boards, sorry.)

Without power

IO1.in to V+ is shorted on the tool board

IO2.in to V+ is not shorted on the tool board

I also see that IO2 is NOT connected to 3.3 Volts, but rather connected to 5 Volts.

Do you have both power LEDs lit when the board is turned on?

@alankilian

THX for the input, especially jumping the connector.

With

M409 K"endstops.sensors"

I observed the input working.

I changed my config.g from

M574 X1 S1 P"20.io1.in" # old
M574 X1 S1 P"^20.io1.in" # new

to activate the pull up resistor.
Like this its back working.

Probably I have messed the line up, can't explain when or why though ...

Thx

GREAT!

I'm glad you're running again.
