I currently have the issue that the top left corner of the bed is further away from the bed than the bottom right corner. I'm pretty sure I didn't have this issue after the first bed levelling. Is there some recommendation as to how often the bed should be levelled? Once a week, after a few days of not turning the printer on, or every time I turn the printer on?
As far as I understand it... Only when you change some hardware thing..... like apply glue to the bed and the last leveling was done without it, the clear glass reflect different than with a glue file = different z end-stop height or changing the nozzle..... but keep in mind every time you level the bed you have to do a "Stor in Memory" (LCD option) to save it.
Ah, that may be it. I have to clean my bed frequently because it gets dusty rather quickly. I'll try to remember levelling it afterwards and see how that goes. Thanks. Wouldn't have thought of the glass reflectivity changing due to the cleaning.
