Osets
Two extruders printing toggles either to press extruder based on G-Code T0 (0 tool) and T1. When the
rmware meets T0, using the main extruder (the right one), and when she meets T1 passes control to
the le of the extruder motor. Basically, apart from steering gear of the motor either extruder, rm-
ware continues to move the two print heads with the only trick to add an OFFSET to the coordinates
of the G-Code to overlay exactly the point of the original coordinates T1 extruder. The value of the o-
set is therefore crucial to have a perfectly aligned on the two extruded laments. Normally this value
hovers around-58.5 mm for X and Y to 0, but it can happen that we should make some readjustment.
To do this we need a le rst to enable us to alternate the two extruders on a design that easily allows
you to recognize the misalignment. In our site you can nd the SM_Test_Bicolor_NG le.Gcode that
has been developed exactly for this purpose.By opening the le with a text editor you can edit the
rst few lines of the le (around line 25), the value written thereupon M218, increasing or decreasing
it according to your needs. The syntax for the F-series is M218 T1 X 35.5-Y0 while the S series is M218
T1 X 58.5-Y0. Start printing with the current values and see how the rst layer is made: we start with
the perimeters that are alternated between the two extruders, so there is a large part of the border
rst, followed by the extruder with ll the second extruder. First carefully observed four: perimeters
are alternated correctly? Are oset only on an axis? Found the correct oset value, you can enter it in
the start g-code of your slic3r ShareBotDualstrusion’s prole.
