Touch the value to select the parameter. Use up and down arrows to alter the values.
Press the Function button to save the setting to the printer’s memory, which is retained when the power is turned off:
Incorrect values will severely affect print quality.

General settings
General settings are designed for advanced use. Defaults are shown below:
Ignore G92 Yes
Enable Hopping Yes
Touch the parameter to change its value
Incorrect general settings will severely affect the 3D-Touch print quality. Do not change any general settings without fully
understanding each setting first.
The following two sections for explain the general settings:
Ignore G92
The "ignore G92" setting is required because of the previous method of managing extruder offsets which involves using the Gcode G92 command.
The user was required to determine the extruder 2 offset value through printing the calibration print. The calculated offset value was then entered
into Axon. During Gcode generation, Axon inserts a G92 offset command to offset the carriage by the user calculated offset amount.
Therefore all Axon generated Gcode files that utilise two extruders contain G92 commands to apply the extruder 2 offsets. A drawback of this
approach is that the Gcode file is printer dependent because the Gcode file contains the unique extruder offsets for the printer that was calibrated.
In order to make the Gcode files portable between printers, the extruder offsets are entered directly into the printer memory with firmware V4.1.0
onwards. This achieves moving the extruder offsets from the Gcode file and into the printer. When the printer utilises extruder 2, it reads the offsets
from memory.
When the extruder offsets are loaded from memory, the Axon generated G92 commands in the Gcode file must be ignored by the printer. Otherwise
the Axon generated G92 extruder offsets will be applied in addition to the printer memory extruder offsets, resulting in print failure.
Typically the desired functionality will be to ignore the Axon generated G92 offsets so the printer memory extruder offsets are applied solely.
However an advanced user may want to use G92 to produce an offset for a number of reasons, in which case the "ignore G92" option is provided.
Hopping
By default this setting is enabled on the 3D-Touch and disabled on the RapMan. The setting is accessed via Settings Menu -> General Settings.
Hop causes the bed to lower 1mm during a non-extruding move, and raise 1mm when the destination position has been reached. This reduces the
