[Tip: Bed adhesion]

If you are confident that the printer is assembled as good as it can be, with all 3 axes at exactly 90° to each other then it's time to calibrate the E-steps.  That will insure that when the printer is asked to extrude 100mm of filament that exactly 100mm of filament comes out of the extruder.  When the ratio of "Volume of Filament In" is exactly equal to the "Volume of the Extrusion Out" then the flow is 100%.  There are lots of YouTube videos on how to do it.

The second thing is to measure the filament diameter.  Just because it says "1.75" on the package doesn't mean it's exactly 1.75.  Cura needs to know the exact diameter so it can do the calculations regarding Volume of Material.  The diameter cannot be changed on standard materials in Cura so you need to copy one and make a custom material.  Then you can change the diameter.  My Matter Hacker PLA is actually 1.72 diameter.  If I were to leave Cura at 1.75 then I would have a built in under-extrusion of 4%.

 

When those calibrations are done and the bed is leveled correctly then the material will have good squish to the bed and should stick.  If it doesn't then we can talk about other things like increasing the Initial Layer Flow in Cura.

That's great information, I will go and learn about all that before I come back. Thank you very much for your quick and accurate response, will report back later!

@javmaster - What did you use the "calibration cube" for?  Did it happen to be to calibrate flow?

Honestly, I was told it's what you need to "calibrate" the printer. I'm new and really learning as we speak, but thought it would show any issues with the settings, but it just printed perfectly, better than anything I've been able to do myself.

Hi, I'm new to 3D printing and been watching videos and reading forums, hope you can help me. I have an Ender 3 v2 with a  BLTouch sensor, have calibrated the bed and got better springs.
I'm using Cura to convert my STL files to gcode, and most of the time I get bad printing with the standard settings (bad adhesion, lines, etc) but if I print one of those calibration cubes it prints perfect!!
Is there a way I can extract the settings from the cube gcode to use in all my prints? It comes locked and can't see any.
Any advice will be greatly appreciated.
