Stay Familiar With Key Components

Before starting to tweak and adjust your ATOM 2 printer, you should be familiar with the names of all the components. If you have just followed the previous manual carefully while assembling your printer, then you are likely to be familiar with all the parts.

If you have received your printer pre-built or have forgotten many of the components, please take your time while following this site or yellow booklet to refer back to the part names, as following the manual step by step is critical to ensuring high quality performance.

Reminder On Techniques With Screws

Almost all the screws on the ATOM 2 are hex screws (fig.1). When turning a screw, remember to apply force into the screw in the direction parallel to it to avoid damaging the screw or the screwdriver. Also make sure the screw-driver or key is completely inserted into the drive before turning.

In the case of something preventing the hex key to be parallel to the screw, use the ball head tip (fig.2) and screw at an angle. However whenever possible, use the flathead tip of the hex key as it allows for more force and is less likely to strip than the ballhead.

Notes On Plastic Parts

Remember that plastic parts are less rigid and durable. When fastening screws into plastic parts, remember not to fasten too tightly as that will cause plastic parts to snap or crack. Adding a washer between the screw and the plastic surface will help distribute the force and reduce changes of permanent damage.

Molded plastic parts often do not have threaded holes, therefore require self-tapping screws or even a tapping process prior to screwing.

Be very careful not to over-turn screws into plastic parts, as that may strip the threads inside the plastic part. In the case of such an occurrence, an M3 screw hole for example can be replaced with a M4 screw.

If the screw hole is too small for the screw, use an electric hand drill or a blade just to chamfer the outer rim of the hole to make it easier to align the screw into the hole.

Notes On Metal Parts

Metal parts are stiffer than their plastic counterparts, therefore it is recommended to fasten screws into metal parts with more force. In the case of ATOM 2 metal parts, it is generally a good idea to make an extra 1/6th to 1/4th of a turn after the screw touches the surface of the object just to ensure proper fastening. If you prefer a more consistent approach or have it available, a torque wrench can limit how much tightly you fasten the screws.

Please keep in mind that there are still risks of damaging the parts by over-tightening.
A screw with a broken head can create a big hassle. If some of its shaft is still partially exposed, pliers can be used to help unscrew it.

The most important tip is to read and follow the manual carefully step for step. 90% of the problems we receive in customer support are caused by failure to follow the manual, and could have been easily remedied by reading over it again.

When assembling parts that have multiple screw holes across the same surface, never screw each screw to the end individually. Instead, distribute the force on the screws evenly and screw them in bit by bit together. We recommend first placing the screws into the holes, in a diagonal sequence, and screwing them in a moderate amount (fig.4), then starting to tighten them one by one in a clockwise or counterclockwise sequence (fig.5).
