Can you explain what you are trying to accomplish?
I think what I would do is change the home() routine to not go so far below the bed while searching for the home position. But the switch should get pressed even if there is plastic on the nozzle. ...
The BeckDac fork is very old. But it is very stable. There are a couple of bugs, like you can't do 3-point leveling because of a small syntax problem. The BeckDac fork will work fine for you...
This is a problem with the GCode protocol. You can't send a capital N because that says what line of GCode was transferred. That is why a lower case 'n' is used. But because it was causing so...
The default number of points (if you don't specify a number) is 3. You should be able to say: G29 n 2 to get 4 points (2x2) probed. Please be aware that it would be: G29 P 2 in the GitHub code. ...
It is difficult to predict. The problem is free time that can be allocated to it. But I'm hoping it will be available for download in a couple of months.
The default is a 3x3 grid if you don't specify the number of points. So you would want G29 u4 T V4 or G29 P4 T V4 depending on where you got your code from.
You might want to try the RCBugFix...
I'm working on an Automatic version with easy adjustments... In 5 or 6 weeks it should be available.
Yes, and in fact, ConfigurationStore.cpp is much altered from that example. But you should be able to figure out where to splice in. And if you can't, you can switch to Mesh Bed Leveling which...
Yes. You would just change the M500 and the M502 code in Configuration_Store.cpp to save and restore it. It should only be a few lines of code to do that . You would probably want to delete the...
I don't think you want to skip the bump. The fact is that it is there. It is going to affect the print. My vote would be to look for a flatter piece of glass.
But with that said... The...
I've been driving all day. I just got a chance to hop on the internet. Your bed looks very level. But with that said, the from right corner is a little bit low and the back left is a little bit...
Do it with a 5 x 5 grid and post that topographical map. That will tell us a lot more.

I don't know what is going on with .STL file downloads. But the source code is in the post. You can cut and past that into OpenScad and generate the .STL file yourself.
That is strange... You have two places where the Standard Deviation jumped up to .01mm That should still be fine, even if you are printing at .2mm layers. But it is strange it jumped up.
It...
I don't know what is going on with .STL files. But here is the source code. Install OpenScad and Compile and Render this. (And Export as an .STL file) A picture of what happens when you print it...
The M48 Z-Probe Repeatability numbers look good. And your bed has a slight tilt to it but nothing too extreme. The Auto Bed Leveling should work. You can try adding a few more points by doing...
Yes. For the 3 Point leveling, the equation (and correction matrix) are set by this code. It is pretty straight forward:
static void set_bed_level_equation_3pts(float z_at_pt_1, float...
No. What you say is not correct. 3 non-linear points define a plane. Not 4. If you are set up for Grid based Auto Bed Leveling, it doesn't matter if it is a 2x2, a 3x3 or a 4x4 grid. The code...
It should not. But if you home towards minimum, that will be the origin. Unless you have set your bed dimensions to have negative numbers. Some people do that to put the origin at the center.
...
Yes, but that assumes you have the orientation set correctly. The default is to have the origin at the front left. But depending upon where you have the origin, you might have to change the...
Yes, your bed is very not level. The Auto Bed Leveling can still print on that but as you move too far from the center the error starts to compound. It should be worth your time to get that much...
Yes, those numbers look OK. The problem is some where else. Let's do a G29 T V4 n5 and see what the bed's topology looks like.
Can you run the M48 command positioned over both the 'tight' area and the 'loose' area. It would be helpful to know those numbers.
I think that is true.
Not if the EEPROM is turned off. And if the EEPROM is turned on, doing a M502 followed by a M500 should clear any bad values from the EEPROM.
The G29...
