Incorrect Wiring Diagram #3

Open aTinyShellScript opened 2 years ago

aTinyShellScript commented 2 years ago

Unless I'm really bad at reading wiring diagrams, this one is wrong. I just smoked my parts fans with reverse voltage.

Please excuse my horrible paint skills but the below shows how it should be labeled.

Note where the nose of the connector on the backside silkscreen is - the connection should be correct, but the connector rotates over on the backside swapping VFP and FP.

The silkscreen shows it with the centering tab facing out, like it does in the diagram. I don't see a way to read this diagram without wiring it backwards. If it is to match how the stepper connector is shown, then the tabs on the diagram for the part fans should be on the inside, not the outside.

Just want to save other people the headache of replacing fans.

I also read this backwards when i wired mine up. fortunately i did all one color wire, and needed to go through and probe to id them, when i caught the reversed wires. it doesnt read well as illustrated. it should be drawn as seen from the same side of the board as the rest, or there should perhaps be a second illustration with the other side drawn out as seen. it would be less confusing. cool board though i love it!

Burning 2 fans due to wrong polarity brought me here . I'm not sure how I could've interpreted it any other way though...

I smoked my fans because of this when I installed this board a while back, then found this thread and fixed it. Now 8 months later I smoked 2 fans again rebuilding my toolhead because I forgot this was incorrect
