Long story short...had an accident/issue and noticed Z sensor is no longer working. No matter the direction it is connected, the light doesn't turn on anymore when near metal. Accident definitely caused huge pulling on the probe to where the tension was so high it actually disconnected *sad face* I didn't notice it until I had recovered (or so I thought) from the issue, and the print head slammed into the print bed and kept going lol.
So I've done some reading on this website to know that likely, the conductor snapped on the inside when it was pulled under high tension.
So I did more reading on this website and found that I need to be careful and determine if that transistor has been fried as well. I went to this site for a schematic and found the ground pin. http://www.makersbox.us/2015/04/ken-ver ... -stop.html
Then I tried to measure PIN2 vs GND and I didn't get 5V.
Is something wrong? When it comes to micro-controllers, I don't want to assume because I know that maybe the voltage isn't even turned on. Can I try anything else - I can't easily hookup to the transistor to force a 12V connection to then see if there is 5V (did I just answer my own question?) that is opened. I just assumed that I should be able to probe the voltage as long as I use a common ground. the 12V connection is only needed to open the gate so current will flow.
What can I do to see if the transistor is working? I mostly don't want to order another induction probe to have it break, and, if i need to order a new printrbot board (I have rev F4 which looks like it doesn't have a current limiting resistor to prevent a short), I do it now vs in the future. FYI I have SOME electronics knowledge, but assume that I don't if any response becomes complicated
EDIT before I even press "POST":
I restarted the system, and now I get 5V. So its just a probe? Geez 25 bucks, any drop in replacements from amazon? I saw other posts, but I'm not looking to upgrade or enhance, I just want a drop in replacement and don't need extra distance because I print directly to an aluminum bed.
NM i found it on amazon, but can anyone tell me what size pin connectors these are so I can rebuild it myself? The part comes with frayed wires and I want to match the connectors from the PB Board (assuming that the board itself is perfectly fine)
