The green bars scrolling across the screen are "ticks". These options are used to adjust the metronome, to make it better fit the song that is playing. Lastly, enabling Double tick will halve the amount of time between ticks on the metronome, making it faster. Enabling Tick on other beat will keep the time between metronome ticks the same as on Half tick, but on a different beat. This will also display the Tick on other beat option. Enabling Half tick will double the amount of time between ticks on the metronome, making it slower. Underneath the universal offset value display are three options that change the speed of the metronome. It can be changed by pressing the Up arrow and Down arrow, or by using the mouse scroll wheel. The current universal offset will be displayed at the top left corner of the screen. The song that was last selected will begin playing, although this can be changed via the jukebox at the top right corner of the screen. Upon opening the Offset Wizard, the user is greeted with a metronome ticking, and vertical green bars scrolling across the screen repeatedly. To access the Offset Wizard, open the Options menu and type offset into the quick-search. For more information on how to do this, see How to use the Offset Wizard. This is necessary when the hitsounds feel out of sync with the music, across every beatmap you play. The Offset Wizard is a built-in tool that assists the user in calibrating the universal offset to the correct value for their device. Now, with Z-offset functionalities like baby-stepping you are essentially telling the 3D printer to add "0.05mm" to where it thinks Z0, instantly adjusting the print head to bring it closer or further from the print bed for a better first layer.See also: How to use the Offset Wizard and Universal offset If you got good at it you could adjust it while the printer is busy printing the skirt, but often it meant canceling the print, making adjustments, and trying again. After that if you started your print and it was too far or even too close, you would have to adjust each of those screws to bring your bed into alignment. You would then adjust the bed (usually with wingnuts or thumbscrews below each of the four corners) to raise or lower the bed so it is uniformly the same distance from the nozzle everywhere across the build plate. Originally, when your 3D printer would "home" it would move to Z0, the theoretical height that the printer's bed is at. Now, when you start your 3D print, you will often have the ability to "baby-step" the first layer, that is "adjust the first layer, during a running print job, to bring the nozzle as close or as far from the bed as necessary." Overall the 3D printing user experience, along with the technology, has made major improvements. The print job was started, the printer was homed (send to the minimum or maximum of each axis), and then got to printing the supplied gcode. In the far off year of 2016, 3D printers didn't really use Z-offsets. Don't apply the adhesive too thick! On any surface you want just enough to keep your 3D prints in place and not so much that it adds considerable thickness or that it's nearly impossible to remove a 3D print, completed or otherwise. Printing PETG and its derivatives on LayerLock Powder-coated PEI doesn't require any adhesive, but printing PLA will necessitate a thin layer of PVA glue stick to keep everything locked down. Be sure to follow the recommendations for each material because you wouldn't want to use sandpaper on a glass bed, but it is recommended to use 220 grit on a LayerLock Garolite bed.ĭepending on the surface, you may even need to use an adhesive as well in order to get the 3D print to stick. Some bed surfaces can get more extreme and require you to scuff it with sandpaper or more lightly with steel wool. Generally, a little rub down of the highest strength isoproyl alcohol (99% is best) will help remove any old residue or oils left by your fingers that would hinder the ability of the freshly laid filament from sticking to the bed. Once you know that the bed surface material and printing material will work together, you are ready to clean and prepare the bed for maximum adhesion. Take a look at our articles about how to succeed with any 3D printing material to gain the knowledge you need for the 3D printing filament you are struggling with and see a deep dive of the bed surface materials that are compatible. There isn't a universal bed surface material that every 3D printing filament will work with some can handle most filaments, but others are targeted for the success of specific filaments. The first layer of any 3D print is the foundation all subsequent layers are built on, which makes it important - it is also critical to remember that bed surface and material compatibility play a role in the outcome of the first layer.
