Getting great prints is hard work and a big part == Types of that is getting the print bed to be absolutely level. With the MatterControl and Part Bed Leveling we make it as simple as it should be. Following these step by step instructions you will have absolutely level prints, every time.After having worked with many different 3D printers, we are very aware of the fact that most printers are very hard to get calibrated. We are also aware that even when they are calibrated, they don't seem to stay that way.==
MatterControl* '''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.* '''s Print Probing / Automatic Firmware Leveling feature eliminates ''': 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 troublesmeasurements when executing moves. By figuring out The probing sequence is activated using the current tilt {{ic|G29}} command in your [[Start GCode]].**Mechanical Switch (Robo or Kossel Pro)**Conductive (Lulzbot Mini)**Inductive (Printrbot Simple)**Force Sensing Resistors* '''Manual Software Leveling''': Has the user measure the height of the bed, MatterControl actively works to maintain at various points using paper as a print's levelnessfeeler gauge. Measurements only need to be taken once. With Print Leveling is applied to the gcode before it is sent to the printer. MatterControl lets you can get leveled prints every timechoose between 3, 7 and 13 point leveling. The more points that are measured, the more accurate the leveling will be.**3 Point Plane: Assumes the bed is a planar surface. This is usually sufficient for cartesian printers, unless they have severely warped beds.**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.
== How Do I Enable It? ==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 ==
[[File:Autoprintleveling1Print Leveling allows MatterControl to figure out the tilt or angle of the bed.png|right|frame|Location Using this information when printing, MatterControl actively raises and lowers the Z axis to make that the printed part matches the tilt bed and will always remain correctly above it. This process ensures that the print remains level regardless of the unevenness of the bed. Long story short, no matter how tilted your bed is, Automatic Print Levelingwill ensure that your print will match it perfectly. <embedvideo service="youtube">https://www.youtube.]]com/watch?v=i5YRtPMwVdk</embedvideo> === How Do I Enable It? ===
Here is how you get to the Automatic access Software Print Leveling feature:
#Select your printer
#Connect to your printer
#Click 'Advanced FeaturesSettings & Controls'#Make Click the window big enough to see Print Leveling'Options' tab#Click To the right of 'Setup Software Print Leveling' select 'Configure'
#Follow the on screen instructions
A step-by-step instruction wizard will open and walk you through the calibration process with clear, easy-to-follow instructions. The only thing you will need is a sheet of standard paper. The software will ask you to help it measure three several points on your bed and when completed Print Leveling will automatically be turned on and ready to help. The whole process is very easy and will take about 3 to 5 minutes.

Long story short, no matter how tilted Print Leveling does not directly change anything about your printer or your print files. It simply allows for the correction of an uneven bed isto be compensated for during printing. If for some reason your bed gets uneven, Automatic Print Leveling will ensure can compensate for it by adjusting the Z axis as you print. This should work for all source files that your print will match it perfectlyprinter can use.

== What Happens If I Disable It? ==Delta printers are great, but they’ve been known to be a bit more difficult to calibrate and level. Our goal is to make MatterControl “just work” with every kind of printer. So, the new 7 and 13 point leveling options were designed specifically to address the calibration issues with deltas.
The Automatic Print Leveling Feature can be toggled on and off by clicking Essentially, the 'Enable' button7 and 13 point leveling options break your printer bed up into either 6 or 12 separate, smaller planes.
If you disable it, MatterControl will not do any work while printing[[File:13-point-leveling. It will not attempt to level the print at all. However if you ever want to turn it back on all your calibration settings are saved and waiting for you when you need them. But remember, when Print Leveling is disabled, you will have to go back to ye olden days of manually calibrating your print bed!png|none|frame|6 Places / 12 Planes]]
Because deltas have three independent towers, with three independent sets of delta arms, it’s possible for one area of the bed to be different than another. The area between the X tower and Y tower, for example, may be higher off the bed than the area between the X and Z towers, or the Y and Z towers. This can’t be properly accounted for with just one plane.
== Technical Notes ==The 7 and 13 point leveling allows MatterControl to account for this and provide a level printing surface through software. While the 3 point plane is generally adequate for Cartesian printers, there’s no reason you can’t use the 7 or 13 for added precision.
'''Mechanical Changes:'''==== Require Leveling To Print ====This is a safety feature that prevents MatterControl from starting a print unless software leveling is setup for your printer.
Automatic Print Leveling works better if your limit switch is on ==== Manual Probe Paper Width ====This allows you to define the top (Zmax). We’ve gotten it to work on printers with width of the z switch paper or other feeler gauge you are using when measuring points on the bottom (Zmin), but it’s a little trickybed.
'''G-Code Changes:'''==== Settings > Printer > Features > Has Hardware Leveling ====This check box tells MatterControl whether or not your printer has a probe or other means of doing leveling on its own. If this is the case, MatterControl will hide the option for running the software leveling wizard. Clicking this check box will *not* add a G29 command to your start gcode

It is also important that the ZJERK (at least in marline firmware) not be 0. If it is 0 it This code will cause help prevent the printer to have to come to a complete stop at every change in z, which will be every move.
