6.3.3 Increasing the adhesion
In some special occasions, like a tall object with a very small contact area with the print
surface, you might need to increase the adhesion. Fortunately PEI is a very chemically
resistant polymer and you can temporary apply other adhesion solutions without damaging
it.
This also applies to materials which would not stick to PEI otherwise, like Nylon etc.
Before applying anything to the bed, consider using
Brim option
in Slic3r which increases
the surface area of the first layer.
For PLA and Nylon blends a simple glue stick does the trick. Glue can be later easily
removed by window cleaner or dish soap water.
For ABS prints, ABS juice can be used and later cleaned with pure acetone. Be very gentle
when applying the juice and do so while the bed is cold. Prints will attach very strongly.
Prepared
juice
can be also purchased in our eshop. Unfortunately, UPS service
does not allow to deliver any acetonebased products due to shipping constraints. In
that case you get only the bottle and ABS from our eshop and you have to source
the acetone locally.
6.3.4 Selftest
(kit only)
The purpose of the selftest routine is to check most common errors when assembling and
connecting electronics and to help indicate any possible errors after assembly. You can run
the
Selftest
from
Calibration
menu on LCD panel. This should not be necessary on the
assembled printers as those are pretested.
Initiating this routine performs a series of tests. The progress and results of each step are
displayed on the LCD. In case of errors found, the selftest is interrupted and the reason for
error is shown to guide users in troubleshooting.
Test consists of
Heatbed
and
hotend
proper wiring
XYZ motors
proper wiring and functionality
XYZ endstop
mechanical settings and proper wiring.
