+Poor gantry squaring can cause a number of problems.\
 Notice that the idlers get "pinched" when moving the X extrusion back/forth (this is shown with loose Z joints).

 - First Layer issues
 - Z belts rubbing against the gantry's printed parts

 ## Method
 
 **1)** Modify the `timeout` setting your `[idle_timeout]` config section. Set it to an arbitrarily high value (in seconds).
-- This just gives us time to work. We need the motors to be energized and holding for the whole process.

 - This does two things:
  - Somewhat "locks in" your QGL at its state in full thermal expansion.
  - This has helped a number of people with their first layer issues.
  - **Stabilizes your gantry**. 
  - If you had it "tight but not too tight, so the Z joints can still articulate" (as is often recommended), you will notice that your gantry displaces back/forth while printing.
  - This can help with ringing and layer consistency.
