Endstops not stopping x/y carriage

Recommended Posts

Hello,

I just finished assembling my ultimaker original and I am having an issue homing. Using the ulticontroller, I went to auto home and it went to the front left corner(as it should) but then the motors continued moving. The endstops click and are wired properly. I updated the firmware through Cura but still no change. I have narrowed it down to the red front left endstop(#4 in the board).

Thanks,

Tyler

It could be a bad endstop. Find someone with a multimeter and measure the resitance when the endstop hasn't triggered - it should be an open (infinite ohms or certainly > 100k ohms) then the more likely problem - close the switch with your finger and measure again and it should be 0 ohms ( < 10 ohms is good enough). It's probably a bad wire. If this test fails then check again where the wire connects to the switch.

if this all passes you could have a faulty board (most likely missing a resistor) or it's plugged in the wrong place (check instructions). You can also install pronterface on a PC and connect it through USB and it will tell you which switches are closed and you can test them all by pushing on them.
