does tightining your heatbed ruin your calibration results?
Hi
I redid the whole calibration process of my printer yesterday and performed a successful print of Prusa badge. Today I tightened two bolts on the heated bed then proceeded to print Prusa buddy but it was complete hell as layers where not sticking to heated bed even when printing the same Prusa badge which I printed very well Yesterday!!!
That's why I want to ask if tightening the heated bed will miss up your calibration results??
I'm thankful for any assistance.

Adjusting the tension of those screws is actually a manual form of calibrating, so, yes.

So I believe I should redo XYZ calibration sequence followed by first layer calibration?

I would just do the Z calibration and make sure your first layer / live adjust Z is good. There's no need to rerun the tedious whole XYZ calibration if you've done it already.
For an ISO M3 coarse pitch thread a used on these screws, it will tighten down 500 microns for each turn of the screw. In my experience, 50 micron changes are noticable in first layer quality, so probably if you turned it more than a 1/10th of a turn, you have significantly affected things 🙂
