Understanding the Custom Button Functions
Button Name
Function
Set Home
This sets a new home (0,0,0) position for your r3bEL mini printer. This
function serves as a manual override to the default setting, such as for
adjusting the home position based on differences in needle tip heights. Note
that once you turn off the printer or use the Home All function, the home
position will restore to the factory default.
Set Z0
The Set Z0 button adjusts the Z-height home position only but is similar to
the Set Home button in that it serves as a manual override. Note that once
you turn off the printer or use the Home All function, the Z0 position will
restore to the factory default.
Get Position
This button provides the exact x, y and z position of your printer. The readout
will appear in the command window.
Move to Front
This button moves the extruder to (0,52) along the xy plane.
P0, P1, P2 and P3 These buttons move the extruder to each of the 4 calibration points on the
printer at the respective corner x-y positions. P0 is at (-48,-52), P1 is at (-
48,52), P2 is at (48,52) and P3 is at (48,-52).
Extrude 150 mm
This button moves the extruder plunger down by 150 mm in distance,
extruding whatever liquid or material is in the syringe.
Extrude 50 mm
This button moves the extruder plunger down by 50 mm in distance,
extruding whatever liquid or material is in the syringe.
Extrude 5 mm
This button moves the extruder plunger down by 5 mm in distance, extruding
whatever liquid or material is in the syringe. This is useful for priming the
needle when the extruder plunger is already in contact with your syringe
plunger.
Extrude 1 mm
This button moves the extruder plunger down by 1 mm and is useful for very
small increments of extrusion.
Retract 150 mm
This button moves the extruder plunger up by 150 mm. This is often used
when you want to unload a syringe.
Retract 50 mm
This button moves the extruder plunger up by 50 mm.
Retract 5 mm
This button moves the extruder plunger up by 5 mm. This is useful for
alleviating pressure buildup in the syringe needle tip (for small needle tips).
After a print, retracting by 5 mm can prevent material from dripping or oozing
from the needle tip.
Retract 1 mm
This button moves the extruder plunger up by 1 mm for very small
increments of motion.
