The PEI sheet doesn't work for shit. It works beautifully on my other printers but on this one I genuinely can't get anything to stick to it. I'm certain it's either a bed leveling or Z offset issue, but the crappy sheet that came with the machine, all scratched to shit, works much, much better.
## Problems?
###Non-functional/detrimental bed meshes
### Non-functional/detrimental bed meshes
Bed meshes don't seem to work properly. I can get wildly different bed meshes without ever moving or adjusting anything on the machine, leading me to believe that the BL-Touch probe might have some issues (or may not be a genuine part, I'm not certain.) It might be worth looking into something else for Z probing.
### Bad PEI plate, maybe
I can't get anything to stick to the PEI plate I bought, which sucks because it's the ONLY build plate I bother using on other builds.
### No webcam
For whatever reason, I curently cannot get the webcam working.

The printer is running Klipper ([GitHub repo](https://github.com/Klipper3d/klipper)). There is a host component (setup on the Pi) and the firmware component - it does not work independtly, as a lot of the tuning and tweaking is stored on the host computer.
## Management
You can browse to the IP address of the printer in a web browser to get to the Fluidd interface - all management is done through there, including updates to Klipper and installed plugins. Any commands that are listed below need to be entered into the Console in the Fluidd interface - there's a small one on the main screen or a larger console window if you click it on the left-hand side of the window.
## Tuning
### Z Offset
[Official documentation link](https://www.klipper3d.org/Probe_Calibrate.html)
**NOTE:** I've hda to re-adjust the Z offset fairly frequently, sometimes between each print. It's not a large task, but I'm unsure if there's an issue with either the probe or the bed screws or the bed itself - just do not rely on this to be accurate over a large amount of time!
Home all axes and then enter <code>PROBE_CALIBRATE</code> into the command line. From there, adjust the Z offset in small increments using the on-screen arrows until it is close enough to the bed that you feel resistance when you drag a sheet of paper below it. You just need to feel enough drag to be noticable - it doesn't need to put up resistance
### Bed Leveling
[Official documentation link](https://www.klipper3d.org/Manual_Level.html)
Once the Z offset is set, you can now manually level the be by entering <code>BED_SCREWS_ADJUST</code> into the command line. The machine will then go to each corner one-by-one while you adjust the screw knobs and repeat the paper test, like in the Z offset section. If you need to make an adjustment to the screw (more than 1/8 of a turn), click "Adjustment", if the setting is fine, click "Accept" - once you accept all four corners in a row, the bed is leveled.
## Bed Mesh Calibration
[Official documentation link](https://www.klipper3d.org/Bed_Mesh.html)
**NOTE:** I'm not certain this is 100% necessary as this unit appears to have a pretty dang flat bed; my results have not been much different when using a bed mesh. I feel that the BL Touch probe installed is either wonky or inaccurate. If and when I switch this machine over to hard mounts, this may be a more important set.
