[patrick-van-der-blij 0]

i have a 4mm glas plate on my heatbed so that is flat.

can somebody help me?

What is preventing you from raising the last corner 0.5mm? Is the screw running out of threads? If that's the case, have you tried tightening every other corner a little bit more?

if rais that the oposite corner lowers 0,5mm.

i think the problem lays in the bearings in one corner.

How are you leveling it? are you using piece of paper to gauge the nozzle height? are you making sure that at one of the bed screws is raised above the bed to prevent fouling and are setting that one last? are you checking that the bed is free to float on the springs and is not binding/fouling? are you going around the bed at least twice as any adjustment on one screw affects the setting on every corner. without being there to see ,its difficult to know for sure.

I had a similar problem, the (wooden) bed was a little warped, so one (front) side was lower.

Because of this, the tension of the spring at this lowest corner was minimal compared to the other corners.

To solve this, I added 2 washers between the spring / Plexiglas printing bed, so the spring gets more compressed.

Now there is more spring-tension pushing against this corner of the bed, so it levels upwards.

Hope this solves your problem.

you can also globally bring all 4 screws down by 4-6-8 turns (2-4mm) to regain some spring tension, and then also lower tee z end switch. or if you have short and flimsy bed springs, replace them with better and stronger and longer ones.

thanks for the reply,i have solved the problem by lowering one bearing at the front ,i measured the axes heiths and saw that one bearing was a half mm-one mm off position after corection the problem is soved
