Mars Pro WILL NOT ZERO - HELP !

[k.i.a.]

I still can't print properly.... the print grows all distorted... I think the plate doesn't align properly... when I turn the screws to set Z=0 it moves as I turn them.. there's no way the plate stay still... and when I attempt a print I have to move manually the plate a tiny bit in order to avoid the grinding sound.. it's ridiculous... and I am sure I am not expert.. but this printer is not user friendly and it's really annoying losing days trying thousand times to set the plate with a paper sheet.. two sheet.. maybe 3... it's honestly very frustrating
I tried to set my room temperature to 25 degrees in order to avoid the resin to be too dense.... but I failed all my prints and the grow deformed even if they have tons of supports...

more the plate is closer to one of the anchor points for the resin tank.... so I'm starting thinking my printer is not ok... and could be assembled badly...

at the moment... only the the test print worked.... every other... no way....
