→The Slice Engine list only shows MatterSlice. Where are CuraEngine and Slic3r?
Your printer has hardware leveling which allows it to probe the height of the bed before each print. Other printers don't have this feature, so for them MatterControl has the option to use [[Options/Software_Print_Leveling|automatic software leveling]]. This is where you measure the height of 3 points on the bed using the piece of paper.
If you try to use both types of leveling at once, they will conflict with each other and cause problems. This is why the option for software leveling is now hidden if you have a Robo or any other type of printer with a probe. For more information on the various types of leveling, and how to configure them, look at our article on [[Automatic Print Leveling]]. If your Robo is having issues with leveling, check out [http://forums.matterhackers.com/topic/9/what-to-do-if-your-robo-keeps-trying-to-print-up-in-the-air this post on our forums].
== Does MatterControl work on Windows XP? ==
== How do I clear the application data? ==
If you are having a problem with MatterControl that is not fixed by re-installing, you may need to delete some of the data that MatterControl saves on your computer. This data will persist, even if MatterControl is uninstalled so remove that folder if you want to completely reset MatterControl to a clean slate. You can also temporarily rename the SQLite database file ({{ic|MatterControl.db}}) to see if your settings are the cause of a problem.
'''Windows''' On Windows, MatterControl keeps the user's library and settings in {{ic|C:\Users\{user}\AppData\Local\MatterControl}}. '''Mac/Linux''' On Mac and Linux it is the user's data library and settings are in {{ic|~/.local/share/MatterControl}}. This data will persist, even after MatterControl is uninstalled. Remove that a hidden folder if you want to completely reset in your user's home folder. '''MatterControl Touch T10 or T7''' Follow these steps: #Swipe down from the top right of the screen twice to a clean slatebring up the Quick Settings menu. You can also temporarily rename #Choose 'Settings'.#Navigate to 'Apps'.#Choose 'MatterControl'.#Hit 'Clear data'. !Do not click 'Uninstall'!#Re-launch MatterControl. If you do not have sensitive data in MatterControl, sending the SQLite database file ({{ic|MatterControl.db}}) to see if your settings are the cause of or a problemzip of the MatterControl folder to support@matterhackers.com can help us track down bugs and is appreciated.
== MatterControl Touch will not download an update and Cloud services do not work ==
== When I restart my printer, values of Steps per mm return to the firmware's default value. How can I change this? ==
It is likely your printer's firmware does not allow EEPROM to be saved.
In order to apply your settings, you can either update your firmware to allow for EEPROM changes or you can add custom G-Code to the "On Connect G-Code" section in MatterControl. Updating firmware requires a fair bit of effort, so it's probably easier to update the custom G-Code. Here's how:
== "Slicing Error" When using Slic3r ==
You may be able to determine what is going wrong by running Slic3r independently. For every print, MatterControl generates a config.ini file that it provides to the Slic3r executable. This is in {{ic|~/.local/share/MatterControl/data/gcode/}}on Mac/Linux and {{ic|C:\Users\{user}\AppData\Local\MatterControl}} on Windows. Run Slic3rindependently, import this config file, and slice your STL. You will then be able to see if Slic3r gives any error messages. On Windows, the Slic3r executable provided with MatterControl is in {{ic|C:\Program Files (x86)\MatterControl\Slic3r\bin}}.

== The [[OPTIONS/Slice Engine|Slice Engine]] list only shows MatterSlice. Where are CuraEngine and Slic3r? ==
Either you have a [[MatterControl_Touch|MatterControl Touch/T10]] tablet (which do not have any third-party slicers included) or the printer profile you're using has more than one extruder configured. [[Multi-Extrusion]] is not supported for any third-party slicers.
