 Prepare the print surface – Keep the surface free of grease. Otherwise, your first layer
will have a difficulty sticking to the print bed. Before starting any of your prints from
ABS, PLA and many other materials, simply wipe the print surface clean with IPA
90%+. Also, you should use Acetone from time to time, when prints stop sticking – but
do not use it on daily basis. PETG is an exception, so do not use IPA
90%+ and Acetone when you are printing with this material. For PETG, we
recommend using a separating agent (e.g. a glue stick). A complete guide how to
prepare the print surface can be found at PEI print surface preparation
 Use proper printing temperatures – Make sure to use the proper nozzle and especially
the correct heatbed temperatures. If you are experimenting with new materials that
don’t adhere well, you can try to bump up the heatbed temperature by 5-10°C. This
way the plastic will stick a bit better.
 Decrease the printing speed – If everything above failed, then try decreasing the
printing speed. The easiest way how to do it is by rotating the knob during the printing
process. Anti-clockwise = decrease speed, Clockwise = increase speed. We suggest
decreasing the speed to about 75% for first three layers, then return it to normal
② nozzle scraping to the hot bed：
When the nozzle is scraped to the hot bed, the material cannot be smoothly
extruded from the nozzle, resulting in no filament come out. At the same time,
the extruder gear will also make a "squeaky" sound because of the
resistance.
