I am trying to use the pearl laser and when i get to setting the z origin nothing is happening i followed the wiki like it says "set new origin, then press z but its not working for me does anyone have an idea what i might be doing wrong?

Push escape then Z and set focus. Sequence xy button, left arrow until reaches far left, reset xy answer yes, will ask if your sure say yes, escape, z button set focus, z button. On the second push of the z button should take the head to the far uppet right. Note: when you push z the first time you can move the head around with the arrow keys on the right side.

Is the Z stuck at the bottom of travel? This will happen if the prior user lowered it all the way down onto the homing/limit sensor and powered off there
The recovery procedure for that is on the wiki, takes like 2 minutes
