== Types of Bed Leveling ==
* '''None''': The print bed is leveled physically/mechanically. Most printers are capable of using this method as a fallback. Usually there are adjustment screws under the bed.
* '''Probing / Automatic Firmware Leveling''': In this case the printer is equipped with some kind of probe or sensor for measuring the height of the bed. The firmware then takes into account these measurements when executing moves. The probing sequence is activated using the {{ic|G29 }} command in your start gcode[[Start GCode]].
**Mechanical Switch (Robo or Kossel Pro)
**Conductive (Lulzbot Mini)
**7 Point Disk: Approximates the shape of the bed as a cone. This is good for small or well calibrated delta printers.
**13 Point Disk: Approximates the shape of the bed as a bowl. This is the best solutions for larger delta printers with severe calibration issues.
Probing and software leveling should not be used at the same time, since they will conflict with each other. If MatterControl 1.5 sees that you have software leveling enabled and there is still a {{ic|G29}} in your start gcode, it will be ignored. In future versions there will be a warning to let you know this is going on.
== Software Leveling ==
==== Firmware Changes: ====
It is also important that the `ZJERK` (at least in marline Marlin firmware) not be 0. If it is 0 it will cause the printer to have to come to a complete stop at every change in z, which will be every move. In Marlin firmware you can find this in Configuration.h line 195 (or there about). We set it to .2.
<code>#define DEFAULT_ZJERK 0.2 // (mm/sec) can't be set to 0 for bed leveling to work.</code>
Or add the following to your [[Settings/Printer/Custom G-Code/Start G-Code|start G-codeCode]]:
<code> M205 Z.2</code>
