Something is wrong … and I do not know what it is
-
hi…
i have tested with another wires, checked wires in motors.... and dont works, similar behavoir.....
:C
-
What can I do?

Hi,
i replaced BlTouch witj Mini IR Sensor… and until yesterday works fine, but this morning think something is wrong.
Why say this?
A- Because before, when i power on printer flashes, and now, no flashes at start
B- Because before, when i head is near bed, a light power on, and now nothing.
C- And the last... in webcontrol when head was near bead, in Z-probe, marked arround 500, and now marks 700 with grey background.Some idea?
Thanks
The most likely cause is that there is a bad connection between the IR sensor and the Duet, most likely in the crimp connection at one end of the cable, and probably in the ground wire. If you have a multimeter, please measure the voltage between the VCC and GND pins on the sensor. It should be 3.3V.

hi,
i have do some test:
1- I have dismount Mini Ir Sensor from Nozzle, and put him near board, with short wires, tested.
2- I have measure voltage between VCC and GND, 2,84 V.
3- I have put close a surface… some photos, the same yesterday...FIRST TEST - ON A METAL SURFACE
SECOND TEST - SEPARATED 2 MM METAL SURFACE
the lights do not turn on …..

It's strange that it is only getting 2.84V and not 3.3v Please measure the voltage between the +3.3V and GND pins on the Z probe connector, to see whether the Duet is providing insufficient voltage or the problem lies in the cable.

hi,
now different measures, now 3,24
Duet Shocket
Ir Probe Entrance

Thanks. If the sensor is getting 3.26V but the red LED doesn't light up when you put a piece of paper below the sensitive area, then it has developed a fault. I will send you a replacement.

PS can you confirm that your address for delivery of the sensor is the same as it was when I shipped the original one on 30 October?
-
Yes.. The same.
Thanks -
Hi,
confirm has arrived 1 hour ago….
thanks
