Manual bed level UI nozzle placement sub-optimal for larger bed sizes about klipperscreen HOT 7 CLOSED

In the log you should see one of two things

"Bed screw locations" will show up if it's using your configured values.
"Calculated screw locations" will show up if it isn't.

from klipperscreen.

You're correct in the calculation. I think there are some things I can do better in terms of getting it closer to the edge. I'll take a look at this, but please check out the bed_screws configuration in Klipper. If you have four "screw" locations defined there, the bed level panel should use those locations instead of calculated locations.

I added a section like this in my printer.cfg. Restarted klipper and confirmed it was loaded. I see a difference in the nozzle placement but it does not seem to align with my settings. I them modified it again and it is not changing the location of the nozzle. I don't see much in the KlipperScreen.log file to tell me what values it extracted from my printer config file.

Here is the current content of my settings.

[bed_screws]
screw1: 40,40
screw2: 410,40
screw3: 40,410
screw4: 410,410

I'll do more testing once this current print completed.

When I press a location the only log information I get is this:

This should be in the log when you first open the Bed level panel. If KlipperScreen has been running for a while and you've already been into the panel, you'll need to restart it for that message to appear

I redid my testing and found the screw information. The nozzle is not quite where I expect but it seems it's a problem with how I'm measuring the screw location. This works and I am sure I can finish getting it tuned. Thanks for the great support as usual.

I just realized what was probably happening here. My code was taking into account the bltouch/probe offset, so if you're running ABL it most likely was putting the probe over where you wanted the nozzle.

At any rate, I just made another change to the bed_level panel that allows it to support the SCREWS_TILT_CALCULATE command. Documentation on it is here: https://github.com/jordanruthe/KlipperScreen/blob/master/docs/panels.md#bed-level
If you haven't used the screws_tilt_calculate command, it's a pretty nice helper for manually leveling a bed.
