I'm so lost... I can't get over how difficult it is at times installing things on linux. Sorry this is just small vent.

I've tried everything to install this. I have install python, now I am currently installing numpy. It seems to be taking a while. All error messages that people were getting about command not found or directory not found is what I am experiencing. I almost need exactly what steps/to write out to get it to work.

When I looked for the mesh leveler on octoprint it doesn't appear to be there so I used the URL zip install. I found this (screen shot below)
When I look in the plug in's it telling me my python isn't right at 2.7. I've spent the last two hours tying to get this to work.

Is this the NEW version of the mesh leveler? It doesn't look the same at all with any of the pictures here. I'm just trying to level the bed better. I'm about 1mm off on the right side it seems? Not sure what to do.

Thanks for any help,

any way to get this working with Python 3?

Is the plugin under active development? I made a suggestion via a new issue on the GitHub site, but I found a fork by AndyQ that has more recent commits.

My bed leveling with springs: https://www.aliexpress.com/item/3D-printer-accessories-pressure-spring-hot-extruder-hot-bed-MK2B-MK3-MK2A-and-other-support-special/32849401447.html?spm=a2g0s.9042311.0.0.dad94c4dMQBzn0

Temperatures:
Pinda: 35°C
Extruder: 215°C
Bed: 60°C

Much better than without springs (0.250 - 0.350mm).

Metal changes shape when heated. Recommendation is to heat up bed to print temp, wait a few minutes (5?) and then do the bed leveling. Results might change. Filament inconsistencies is another variable to pay attention to. Filaments with +/- 0.05 have great variance. However, if you always see the same problem on the same side then low chances for filament being the cause. Yes. I think so. I will make a special printer profile to wait 15 minutes or so (G4 S900) before printing large parts.
I think also to take screenshot of different bed levelings at different time when warming up of the bed up to 90°C (my usual bed temp).

I've been reading through the thread trying to get an idea about what to do to get my bed more level. When I started out with the plugin I was at ~0.5 and since playing around it's now gone up to ~0.8 and I haven't been able to get back to anywhere near where I was. I've mostly been playing around with the y holders on the right side unscrewing and screwing back in and other that a tiny bit of variation haven't seen much improvement. Is there a specific technique I should be using? Could it be something else? I've taken the entire build platform off and re-tightened all the screws in the correct order again wondering if maybe that could have accounted for it but I saw almost no difference. Lost here trying to figure out what to do. It happens after time. The left and the right parts of the X axis are not at the same level. It may happens some step shifting or some other shiftings. The 2 Z motors doesn't produce the exact amount rotating. You can make a Z calibration but you won't get the result anymore.
What I have done is to hack the plugin to know if the bed is still flat despites the difference of high between the left and the right. You see your bed seems still flet but with a slope between the left and the right.
Bed levelling after Z calibration:

Corrected bed representation against the slope:

You see on the second picture, I still have a flat bed. It is the X axis which is not parallel to the flat bed.

Here is the cold leveling I was able to get, looks great and all but my first layer still sucks. It's too squished on the right and low on the right, even with adjusting 50um up/down on the mk3 it still is crap.
What factors play into this measurement?
I was under the impression a level bed = a perfect first layer (at least..).

Help!

Not sure if this was already in this thread, I found it somewhere, don't recall where. But just in case:

For anyone who is planning on using wave washers, getting screw, bed, standoff, washer, and carrier all lined up is a royal pita. The tweezer part of the item below looks like a great solution. Not tried it yet, but I need to rebuild my Y-axis (for other reasons), so will use it when putting bed back on.
