| - Home the machine on the Manual Controls tab and make sure that works okay. Check the z-axis homing to make sure that looks right while we continue to work on getting that dialed in and consistent. If it does not look okay, you can turn off the motors using the button just to the left of the button with a P on it and then manually turn the z-axis rod to get the z-axis set where it should be. Report any problems to a board member so we are aware of them and can keep refining this process. | - Home the machine on the Manual Controls tab and make sure that works okay.

| - | - Load an .stl file using the Load button. An image of your piece should appear in the 3D View tab. IMPORTANT: If your piece is not symmetrical, it will print inverted on the x-axis even though it looks correct in the 3D View tab. To correct this, click the Mirror Object button on the Object Placement tab. Your object will now appear to be inverted, but should print correctly. | + | - Load an .stl file using the Load button. An image of your piece should appear in the 3D View tab. **__IMPORTANT__:** If your piece is not symmetrical, it will print inverted on the y-axis even though it looks correct in the 3D View tab. To correct this, click the Mirror Object button on the Object Placement tab. Your object will now appear to be inverted, but should print correctly. (This happens because the axes on this machine are set up so that x increases to the right and y increases to the front. If you think about it, you'll realize that this is not the way a standard coordinate system works. And it's not the way the Repetier coordinate system works either... If you're interested in trying to fix this, please let me know and we can discuss!) |
| - On the right side of the screen, select the slicer tab. The slicer should be CuraEngine, the Print_Configuration should be Slower_Speeds, the Speed slider should be set to Slow, and the Filment Setting for Extruder 1 should be PLA. As ew use the printer and get other types of filament, some of these may change, but initially, these setting seem to give fairly good results. | - On the right side of the screen, select the slicer tab.
