I b...Hi Don, just wanna take the time to thank you! I busted the Y axis optical switch while I was servicing the machine, so I replaced it with a new one, but like you said, it wouldn't work! I had no idea what it was, Checked every cable, I clean the board, nothing worked, thanks to your post I realize I had to change the resistor, worked like a charm!! Now it's working just fine! I might make a video for YouTube, because I notice a lot of people having the same issue but I couldn't find an answer on any video, I will give you the prompts of course, and send them here to your blog, thank you again, people like you inspire me to keep learning.

If so replace it and the resistor.<br />You should not have to change the resistor unless you have just changed the sensor component. That said if nothing else work replace the sensor component and resistor.DonKJrhttps://www.blogger.com/profile/14497402158163702122noreply@blogger.comtag:blogger.com,1999:blog-247130680149573043.post-58177840433733436042020-02-10T07:26:36.301-08:002020-02-10T07:26:36.301-08:00Hi Don, my K40 suddenly after one month of good us...Hi Don, my K40 suddenly after one month of good use is behaving erraticaly. Once turned on it tries to home away from the Y endstop. X carriage also does weird things. Its strange because yesterday it was working nicely. Should i replace both 1k resistors for 100ohm ones in both endstops?
