When I’m in the Makerverse program I can see the green “Sleep” button, the red “Reset” button, and the blue “Reset Chains” button but I don’t have the “Set Home” button and I can’t find it anywhere.
you are using makerverse. check out this post on the basics of makerverse. Essentially you zero the working axis relative position (right side) where you want the temporary home to be while the machine axis locations (left side) keep the absolute machine position. Right side and left side are the number columns in the location widget on the right side of the screen.
