First Layer Not Sticking / Parts Coming Loose; Grinding - Intamsys FUNMAT PRO User Manual

First layer not sticking / Parts coming
loose
The most common cause of this problem is
improper leveling of the build plate. It is very
important that the build plate is perfectly leveled in
relation to the movement of the print head and that
the distance between the nozzle and the plate is as
close to perfect as possible.

Grinding

Grinding happens when the motor tries to push
filament through the nozzle but, for various reasons,
it starts to slip on the filament and instead grinds
the plastic down. The more it grinds the filament,
the less grip it is able to get and eventually it is not
able to move the filament in or out.
One source of this issue may be the refraction speed
being too fast. Try reducing retraction speed by 50%.
Another solution may be to increase extruder
temperature by 5-10℃. Finally, you can try reducing
the printing speed to solve this issue.
