#first layer issues...

Hello. I got a CR-10S from a friend and I've been trying to use it. However, I am having trouble with the first layer. I used their e leveler device and then printed out the eleveler squares code (not a 3d model, just gcode) and it turned out wonderfully! The first picture I've posted is the squares print.

I had previously attempted to print a benchy and I noticed the first level was translucent and was too close, see the second picture.

After printing the squares gcode, I used a calibration file to generate gcode using Cura's default settings for the CR-10S (the same slicer settings I used for the benchy). However, the first layer refused to stick and the lines were too thin and stretchy. See the third picture. I had leveled the bed using the paper method where I should just feel a bit of resistance at every corner. The first picture shows that my bed is level and the second picture shows that the overall print settings are okay... so I'm at a loss of how to proceed.

It seems like you have done a great job troubleshooting so far. Here are a few additional steps you can try to improve your first layer adhesion:

  1. Make sure your bed is clean. Any dust or residue could prevent proper adhesion. You can use isopropyl alcohol to clean the bed before each print.
  2. Check your nozzle temperature. If the first layer is not sticking, the nozzle may not be hot enough. Try increasing the temperature by 5-10 degrees Celsius.
  3. Adjust your first layer height in your slicer settings. You can try increasing the first layer height slightly to improve adhesion.
  4. Check your filament diameter settings in the slicer. Make sure it matches the actual diameter of your filament.
  5. If the lines are too thin and stretchy, you may need to adjust your extrusion multiplier in the slicer settings.
    By trying these steps, you should be able to improve your first layer adhesion and achieve successful prints. Good luck!

This looks like a z offset issue. The bed could be leveled but if the nozzle is too far from the bed it’ll cause this. Have you tried lowering that at all?

Does increasing the z offset lower or raise the nozzle relative to the bed? I had increased z offsets because two of my leveling knobs couldn't go lower without losing grip on the spring. Since I couldn't bring the bed down any further, I increased the z offset by 0.2

Also, wouldn't setting my z axis to zero after homing my axis be the best place to level with? Or does homing not take z axis into account?

Is the z offset measured in millimeters? Also, I had my printer bed and nozzle heated during leveling with paper, does preheating make a difference?
