A lot of times I’ll see someone asking for help online that goes something like this:

“I just changed the bed on my 3d printer to XYZ, bought a new extruder from LMNOP brand, updated my retraction, temperature, and speed settings, and now nothing works. How do I fix it?”

My advice to these folks is almost always to back it up a bit. What ends up happening is that they change so many things all at once that it’s impossible to tell which configuration change or setting change was the one that threw everything off.
