If I click the home button, my z axis lowers very slowly (it should be going up!!). This is all that happens. Any idea what’s going on? Even if I hit the limit switch by hand nothing happens, just continues to lower the Z. ---

Did you do the machine setup in Easel? ---

It’s nothing software related 🙂 ---

Machine setup establishes the correct firmware settings in Grbl to make your machine behave. ---

I understand 🙂 The firmware hasn’t been touched since my last calibration. I literally turned the machine back on and this problem happened. and unless the arduino re-flashed its firmware without the machine or pc even running, its settings are fine. ---

Ok, sorry. You didn’t make it clear that you had the machine working and this was a new problem. Since your Z homing switch didn’t affect the homing operation you could try this: > [@\[Guide\] Using Grbl to debug your homing switches](https://community.inventables.com/t/guide-using-grbl-to-debug-your-homing-switches/16588): > > If you are having difficulties with your homing switches you can do a quick test with Grbl to see what the state of the homing switches is from Grbl’s point of view. NOTE: In order to use this procedure you need to have grbl Version 0.9j or later installed on your Arduino. To do so, you use the Grbl status immediate command ? (question mark). This command asks Grbl for its current value of some of its state information. For the purpose of this article we are interested in the homing switch stat… ---

interesting stuff thanks! I didn’t know that was possible
