Hobby servo for probe shutting down duet.
-
@cj19944 that servo is rated 500-900mA current draw. How are you supplying 5V to the 6HC?

I get it of the main board. Is this wrong sorry im not an electronics person -
@arnold_r_clark
What temp will it work up to, maybe I need to change -

@cj19944 that should be correct,

@cj19944 drawing 900mA from the 5V rail of a 6HC is OK. But the servo may have a higher stall current. The maximum external 5V load supported by the 6HC is 3A.

@dc42 i have taken it from the 5v .i05 rail should i use another pin.
Thanks -
@cj19944 Hi guys fixed this problem by switching 5v pin to my 3.3v pin on my set up must of been something to do with stall current something I obviously don't understand to much, appreciate everyone's help.

@cj19944
All this did was just not shut the machine down. -

the servo you linked did not look like it would work properly run from 3.3V. can you send a picture of how it you have it wired?

This was my original setup, then i swapped 5v to the 3.3v power the machine did not shut down but the motor also did not move. I have ordered the Schottky diode and 220uF capacitor and an external 5v source for if that does not work. If you wouldn't mind if confirming i do have the wires wired up correctly that would be much appecitated thanks. -
@cj19944 Just used an external 5v power supply and all is working okay thanks again.

@cj19944 thanks for confirming it. Its interesting to see that that servo has a high enough stall current to drop the 5V supply on the 6HC.
