Hi ! I struggle with a failure with my toolchanger.
i use the latest carousel.comp.

the atc is controlled by 3 proximity sensors.
the proximity sensors are npn normaly open.
i connect them to my mesa 7i92t.
on the mesa 7i92t i have the pullup jumper selected.

If i connect the sensor to 24v,gnd from mesa (on the idc connector) together with gnd of the 24v supply and the signal cable to a input on the mesa i see the pin change the state if i hold the sensor to a screw or something metallic.


original on this machine the signal cable goes to a 22k ohm resistor which is connected to ground. Then it goes to another 22k resistor in series.. which haves a ceramic cap 1nf to gnd. and then to a 74c14 schmitttrigger.. from there it goes to the mcu.

i will draw a small sketch later.

in linuxcnc i debounce the pin with the value 3.
the sensor cables ate not shielded.. and are near to the main drive and maindrive cables.. main drive becomes a 280v pwm signal up to 5amps.

so sometimes the atc stops turning anywhere .. i think it get count signal.. but thete is no count signal.

should i clean the signals like original controller it do?

thanks

Ok, I will of course do so, but will take a bit until I have access to the machine.
Question: there is also a 7i37 connected to the 7i80-  has the 7i37 be disconnected also? Guess so.

Yes I have that.
