What does a good first layer look like on the 300x 3D Printer?

When printing, you want the filament to come out at about a 90 degree angle like this example from Matter:

If the build surface is bulging up in the spot you're printing, then the nozzle will print too close over that spot and be difficult to remove.

The BLTouch helps to keep the consistent layer height between the nozzle and the build plate for printing.

If your print doesn’t match the test print in the box below, your BLTouch is not calibrated correctly. On your printer, go to the menu > tutorials > BLTouch calibration to raise or lower the nozzle for printing. Once it's calibrated, you won't have to calibrate it again very often!

This is what the test print should look like when finished. Notice the 90° angle of the square and the consistent layer lines. 

If the nozzle is not close enough, the layers will not stack correctly.  Here is an example print from a nozzle that is too far away. If model comes loose while printing, the nozzle should be lowered.

If the nozzle is too close, your print will look smashed like this example. The  nozzle can also be so close that it drags into the build filament didn’t extrude. In this case, it should be raised.
