Scroll Wheel/Encoder
In earlier generations of Palette v1.0 and , the scroll wheel/
encoder was a separate assembly between Palette and the printer.
With Palette 2 and 3, the scroll wheel/encoder is actually built into the
unit, so there's no need to attach this to your printer physically.
The Scroll Wheel/Encoder uses its filament-measuring capabilities to
record
Pings
.
Pinging (extrusion based in accessory mode,
digital pinging in connected)
A
Ping
is a checkpoint in a print. Palette knows how much filament a
printer uses over time, but Palette needs clear checkpoints to
understand how much filament the printer
was supposed
to use during
this time. Pings are how a printer says: "
Palette, I'm 3% of the way
through the print. Now I'm at 7.5%. Now I'm at 11%.
" Every time a ping
occurs, Palette compares how much filament has been used with how
much the printer
was supposed to use
(in the GCode): "
The printer sent
us a Ping, which means we're 10% of the way through the print. We have
used 5m of filament, but according to the SEEM file (.maf, .mafx, .mcfx)
from Canvas, we should have used 5.2m by now.
" Palette then uses this
information to adjust future filament segment lengths.
If you are printing with accessory mode, you may find yourself wondering
"why does the printer pause over the transition tower?"
, these are Pings.
Pings (and transition/purge towers) are added to the GCode when the file
is processed by Canvas. The
Ping Signature
is a set of unique and
recognizable GCode commands that Palette identifies as a ping (using
the Scroll Wheel/Encoder). Currently, the Ping Signature is a 13-second
pause, 20mm of extrusion, and then another 7-second pause, after which
the print resumes.
