Load cell z probe

[Pitsweer]

Ok so I've got the load cell and all that goes with it. I'll be using the adruino nano to send probing signal to the duet wifi. What I'm not sure about is if I can get 5v from the duet or duex5 so give power to the nano and where to connect what so I can send M42 to zero the load cell beforw every probing sequence. And how do I get the nano to tell the duet that a probe has been done.

@pitsweer it's likely that the chip used to read the load cell will have a response time that is too slow to make a good Z probe.

There's no need to zero the load cell if you monitor it for a sudden increase in load, rather than looking for an absolute value.

Your DueX5 provides 5V power on the 5 PWM/servo connectors. You can have the Arduino set a pin high when the load increases, and connect that to a spare endstop pin on the Duet.

@dc42 the chip I'm using can do 80hz. Normally they do 10.
