<p>I’ve got this proximity sensor which is a 5 V, it doesn’t say it can be used over 5 V. Can I use a buck converter or is it possible to wire it up direct to a 5 V source on the Ender 3 V2?</p>
<p>What I don’t understand is where to wire it direct to 5 V on the printer or if I use a buck converter then where does the 3rd wire go to on the printer?
If it goes to the signal wire on the Z endstop then which one is the signal wire?</p>

Although there are differences in quality between brands, PLA shouldn't need a raft to be printed. Hatchbox filament is not considered as a low quality type of filament; it is economical and has been around since 2013. A raft is a structured platform that is specifically used for high temperature and or high shrinkage types of filament, PLA is not such a filament and shouldn't need a raft. This implies that something is wrong with getting the filament sticking to the plate. Good adhesion requires a levelled bed, a correct initial nozzle to build plate distance (e.g. paper thickness) and possibly an adhesive like a glue stick, special adhesion spray, a textured bed or blue tape, etc.</p>\n"}, {'answer_id': 16243, 'author': 'Greenreader9', 'author_id': 28179, 'author_profile': 'https://3dprinting.stackexchange.com/users/28179', 'pm_score': 0, 'selected': False, 'text': "<p>Please try one (or more) of the following:</p>\n<ol>\n<li><p>Change the temperature of your heated bed (50 - 60\xa0°C)</p>\n</li>\n<li><p>Check your nozzle height (0.15 - 0.25\xa0mm is what I use)</p>\n</li>\n<li><p>Make sure your bed is level (Maybe use a leaving stick (or whatever those bubble things are called))</p>\n</li>\n<li><p>Use adhesion.
