End stops not responding on UM1 - solved

Recommended Posts

I really doubt it. I would put the UM on it's side and uncover the bottom board. Disconnect one of the switch cables and hook up to a multimeter in ohms mode. Push the switch and verify the resistance goes to < 10 ohms when the switch is closed and infinite when switch open.

Probably the wire is bad at either the connector or right at the switch.

You actually only need 3 switches - the left one for X, the front one for Y and the top one for Z. Marlin comes with "software endstops" for the other ends of your axes. The UM2 only has 3 limit switches.

Thanks or the responses. I actually got it to print just fine without having to go through the wizard. Prints look great. The switches work fine, it homes perfectly ever time. I still don't know why the switches wouldn't work with he wizard. But fir now I'm good. Thanks again for all the responses. It's good to know I'm not in this all alone.

Hi Brainmaker!

I have the same Problem/Effect. The Cura First Run Wizard doesn't work. The first Test of the Limit switch failed. Cura doesn't discover the pushed switch. Not this one or another. And the switch is correctly connected and works fine, tested with an multimeter. I think, this is an Bug in Cura.

I say too: It's good to know I'm not in this all alone.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
