Lately ive got the issue that the button sticks, wich causes the Z endstop being pressed all time,
I was already guessing this would happen due the hairspray,
Do you have any advice ?
I guess i will try and leave it like that unstucked, for 3 days and afterwards replace it if it didnt go away.

Wow! That is horrible! The only thing I can think of would be to soak the switch in acetone. But given how cheap those switches are, I don't think I would risk it. I suspect it would be safe to soak it in acetone but the problem is you can't see what is inside. I would be worried the opposite thing would happen. I would worry a thin film of plastic got deposited on the contacts and then everything would act flakey.
I kind of risk the same thing spraying hair spray on the bed with the probe measuring things. But the good news is I'm spraying down and the switch button is kind of shielded. But I'm going to be more careful going forward!

Just as an update, It kinda resolved now,
After a few clicks i gave it every few hours, it kinda became better and better.
I did have a few crashes tho, that it pressed once, went up, went back down and didnt stop immeaditly lol.. Hopefuly that doesnt happen anymore :P
/edit
Just had it again, weird it just goes to the platform, totaly pressed and just doesnt stop lol..
/edit
Well i guess i have found the problem, and a solution, I guess my glass was just to dirty of hairspray that it seem to have probems with it,
I cleaned it and it does it again just fine.Last edited by DrLuigi; 04-22-2014 at 01:35 PM.

I'm Jealous!!! That is amazing! You must have very good equipment!
You can try:
M48 x 100 y 48 V4 E L 8
To beat on the hardware a little bit harder. That will engage and retract the Z-Probe for each measurement and move the X & Y axis around between measurements. Probably, you will get similar results, but not as good as the one you just posted.Last edited by Roxy; 05-07-2014 at 11:00 AM.

I'll give it a try. I'm just using a cheap kw12 switch and a hitec HS65HB servo. This is my first printer (prusa i3 rework), so i'm still dialing it in and getting a feel for it. The bed is con-vexed in the center once it warms up. I was getting pretty inconsistent prints. Once I enabled auto bed leveling and used 25 probe points, everything magically started printing good.
I like your code, it'll at least give me a baseline to work off of to see if the switch might be failing.

A lot of people want to use a 3x3 grid. Probably because in the Configuration.h file it says there shouldn't be a need to go higher than that. But I know 4x4 works much better than 3x3 and 5x5 works a little bit better than 4x4.
How do you know there is a high spot in the center of your bed? (I'm guessing that is what you meant by 'convexed') Did you see that with the T option on the G29 with a 5x5 grid?

Yeah, I did. I tried shimming one corner to see if it'll help, but one washer was too much. It was worse before the shim. You can see the values increase around the center of the bed. Here's my current topography after the attempted shim in the back right corner.
