new retraction calibration
had to add an override from region to ~gcode writer (and gcode),
maybe I have to think about a better system that the current system that will began to transform into a spaghetti monster

+<p>it's preferable to have done the flow and temperature calibration.
 
+This calibration will help you to choose the right retraction legnth for your extrudr and the current filament.</p>
 
+<p>This test will print some retraction test patches</h2>
 
+<p>The goal is to choose the highest temperature possible that doesn't produce artifacts.</p>
 
+<p>First, you have to analyse the tower. Each floor has the according temperature written on it.</p>
 
+<h2>Notes</h2>
 
+<p>The retraction speed should be set to the maximum value your extruder/drivers/firmware can reliably support.</p>
