Changes

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.

<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:

#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'

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.

Print Leveling does not directly change anything about your printer or your print files. It simply allows MatterControl to figure out for the tilt or angle correction of the an uneven bedto be compensated for during printing. Using this information when printingIf for some reason your bed gets uneven, MatterControl actively raises and lowers Print Leveling can compensate for it by adjusting the Z axis to make that the printed part matches the tilt bed and will always remain correctly above itas you print. This process ensures should work for all source files that the print remains level regardless of the unevenness of the bedyour printer can use.

== How Will This Affect My Printer And Prints? =Settings ===Most of the print leveling settings can be found in Settings > Printer > Print Leveling

HereDelta printers are great, even with but they’ve been known to be a ridiculously uneven bedbit more difficult to calibrate and level. Our goal is to make MatterControl “just work” with every kind of printer. So, the Automatic Bed Leveling feature ensures that new 7 and 13 point leveling options were designed specifically to address the print will still be perfectly uprightcalibration issues with deltas.</center>

Print Leveling does not directly change anything about Essentially, the 7 and 13 point leveling options break your printer bed up into either 6 or your print files. It simply allows for the correction of an uneven bed to be compensated for during printing. If for some reason your bed gets uneven12 separate, Print Leveling can compensate for it by adjusting the Z axis as you print. This should work for all source files that your printer can usesmaller planes.

The Automatic Print Leveling Feature can Because deltas have three independent towers, with three independent sets of delta arms, it’s possible for one area of the bed to be toggled on different than another. The area between the X tower and Y tower, for example, may be higher off by clicking the 'Enable' buttonbed 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.

If you disable it, The 7 and 13 point leveling allows MatterControl will not do any work while to account for this and provide a level printingsurface through software. It will not attempt to level While the print at all. However if 3 point plane is generally adequate for Cartesian printers, there’s no reason you ever want to turn it back on all your calibration settings are saved and waiting can’t use the 7 or 13 for you when you need themadded precision. But remember, when Print Leveling is disabled, you will have to go back to ye olden days of manually calibrating your print bed!

== Technical Notes ==Manual Probe Paper Width ====This allows you to define the width of the paper or other feeler gauge you are using when measuring points on the bed.

'''==== G-Code Changes:'''====If the limit switch is on the bottom (printer homes to the bed). Add the following G-code after homing.

If the limit switch is on the bottom (printer homes to the bed). Add the following G-code after homing: <code>G1 Z1 ; raise the extruder to be 1 millimeters above the bed. </code>

'''==== 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.
