Bill Tyler's Mosaic
Mosaic 3D printer, owned by Bill Tyler and hosted by him.
Used 3mm PLA or ABS. It has a heated bed.
The filament that is there can be used freely, as long as it is not labeled otherwise. You may bring your own, and you may have to when the donated and excess filament runs out.
More details will be added, but for now the basics of how to use it are:
1) You need a .stl file, or another of the format that Cura can import
2) Turn on the printer via the switch on the power strip it is plugged into.. Lights may come on from the USB power even though the power is off, so double check -- the LED lights that light the bed should come on if all power is there.
3) On the connected Windows computer, you can move the head and level the bed from the Pronterface software. Most of the time you do not need to adjust anything. You may need to use Pronterface to lift the head from your part (if you pause it) or the bed -- Cura doesn't have a way to simply move the head. Start pronterface by searching for "Pronterface" on the windows start menu and clicking on it. The come port for this printer should be COM6, select that and click "Connect".
4) You can change the filament if needed by removing it from the extruder driver at the back of the machine. Start pronterface, connect, heat the head, and retract filament to make it separate from the hot end. Then there is a little bolt you can unloosen if necessary. You should be able to back the filament out with Pronterface while pulling gently and remove it, and then push the new filament in while extruding.
5) The bed can be covered with blue masking tape from the desk drawer in the white desk behind you, this may be best if printing with PLA. You can also print directly on the aluminum, or use a glass bed which is in the box of filament behind the printer. Hairspray (Acquanet) may be necessary if you use the glass.
6) If you need to zero the Z axis, do it by pressing the Z Home button in Pronterface, then if it is not the right distance (a piece of paper has slight drag between the head and bed) lower the bed and adjust the white bolt/screw in the frame to the left of the bed, that pushes the limit switch at the bed's highes point. You will have to do this if the bed has been changed (glass switched for aluminum, for example). You should not expect to have to re-level the bed.
6) Disconnect Pronterface if you started it.
7) Start Cura from the Windows Start menu. Go to "Machine" and make sure COM6 is selected.
8) Load an STL file with the File -> Load Model File command.
9) Check the settings -- the defaults are a reasonable start, but you may have to adjust them for some prints.
10) File -> Print . The job may be left unattended, please leave a note with how to contact you however, in case someone wants to remove your finished part to use the printer before you return.
11) Turn off everything and clean up when you are done. If the tape tears when removing your part try to re-tape the bed. If you have problems and think the printer is not working, post on the mailing list.
