This is the current situation
Well that didn’t worked out. Let’s try again
Wait until the images show up in the text box before you post
Take the reciever out of the uart port before you try motor detection again, that can mess with detection.

This is not a good fault to see.
I would do a hand test on the motor before attempting to drive it again.
Sometimes if you’re buying used, or troubleshooting, and need a quick way to see if anything might be wrong, you can test a BLDC motor with only your hands. It’s not the most accurate test in the world, but catches most problems.

Ensure motor phase wires are not connected to an ESC or anything else.
Verify the motor spins without grinding or rubbing. Put a tad of sideways stress on the shaft and push it and pull it (while turning) to veri…

Yup. What I have done a bunch of times in the past is set up a thread for someone, then unlist it so it doesn’t show up anywhere public.
Then you can work on it in private, get it just right, then ask me to list it again. Can also do it with a post that already exists if you have put work into it.

A search on that fault code yields
You probably got a bad solder joint or bridge on one of the ADC pins. Try adding some flux and heating the STM32 again. It could also be that one of the AD8418 is dead, but that is quite unlikely. Surprisingly, the DRV8301 has almost never died on me on the VESC6.

So I would inspect your ESC VERY VERY closely (like under magnification) and check for solder balls. It probably has a solder ball laying on it. Cut the heatshrink off and brush it with a clean, dry toothbrush if you can’t do that.
Here are some examples of what to look for

Is it possible that i killed my motor by not putting back the phase wires the way they where?
Sadly taking the reciever out and trying again didn’t solve anything

But then it wouldnt have worked in the first place right?

It’s extremely unlikely that reordering the phase wires would have any effect besides reversing the rotation direction.
It’s more likely that a physical movement of the ESC happened during that process which dislodged a solder ball and it landed on something bad.

I will get the transparent plastic wrap of the esc and make some really close up pictures

and there goes another 100bucks. Got any recommendations for a new vesc? 6.6 or 4.2 and if im planning on making a dual setup in the future can i also buy a dual en use it as a single until i decide to buy the second motor?

Whatever you do don’t buy flipsky. Roll of the dice on quality.
With that out of the way, a cheap esc that served me well is from maker-x.
Alternatively, the vesc is vesc 6 from trampa
