PRINT HEAD OBSTRUCTION
The Head Obstruction firmware error displays when the metal nozzle movement does not correspond to the
motion commands. This can be caused by an obstruction between the metal nozzle and the part. In order to
avoid this error, please make sure to do the following:
●
Keep the wiping station brushes clean and empty the wiping station regularly. If the station is not clean,
material may build up on your metal nozzle and hit the part on the print bed. This is more likely to be a
problem during longer prints. For more information, please review the
Wiping Station
subsection of
Cleaning Your Metal X Printer
, below.
●
Only use each print sheet once.
Reusing sheets may cause issues with the vacuum seal causing
prints to fail.
●
Finally, try to include fewer distinct parts in your builds. This will improve part quality and make print head
obstructions less likely as the head transitions from part to part.
If the Head Obstruction error message appears, the print run will terminate automatically—you will not be able
to complete the print. Instead, you will need to clear the print bed, clear the firmware errors, and install a new
print sheet for the next print.
