Your First First Layer
You might not know it yet but the first layer of a 3d print is the absolute most important aspect of getting a successful and beautiful 3d print.
Are you having bed adhesion issues? Well folks look no further because we have the magic cure for many of your 3d printing ailments.
Getting that perfect “squish”
To begin this journey There is at least one pre-requisite. First you must have leveled your bed. I’ll say it again, you must have a level bed before you can print successfully. Getting an even squish isn’t possible without first grading your lot.
Okay so you have a level bed. Can I just hit print and go? Nope. Sorry. You now have to adjust your Z end stop to make sure your extruder and specifically your nozzle is in the “Goldie locks zone”. So how do you do that? First off you need an idea of what a good squish looks like. There are two extremes that you will see in this process. 1. When you are too high if the filament is even sticking to your bed it will look like thin pieces of hair coming out and if you look really close it will look pretty round. 2. When you are too low the filament will squish so much into your print surface that your extruded filament will be very wide and sometimes uneven. Being too low will often result in your extruder not being able to push the filament through the nozzle as fast at it wants and you might hear clicking coming from the extruder stepper motor. Okay so now you know what not to do, next let’s look at the good stuff. This image shows a nice “squish” notice how the extrusion isn’t perfectly round but is squished down a bit.
