First layer calibration?
Printing looks good. But general question:
When printing first layer calibration, can;t really tell by the pictures and joe prusa youtube on this.
Should the zigzag square or even the Z calibration my way square be solid after printing? Or still can pull somewhat apart?
At the end of the calibration you are aiming to print a single layer *sheet*. It should be possible to peel it off in one and fold it without the threads seperating. If it breaks into lines it is too high, not squished enough. If it is a single sheet but with wavy lines or drag marks on it you are too low.
For most people it pays to use 7x7 mesh bed levelling.
Many beginners have problems with the built-in first layer calibration routine. There are alternatives, see this page by a regular poster here: http://www.muppetlabs.co/3dprinting_mk3_live_z_calibration.html
