Dual Extruder Calibration

thingiverse

Here's a print for calibrating dual extrusion alignment. I set the bottom part to the primary extruder and the top part to the secondary extruder to be offset calibrated. The top part is elevated from the platform so that if the secondary extruder offset is too low, there is some margin so that it won't crash into the build platform. The hole aligns with the "top" of the build platform to clock how it was printed on the build platform and identify which axis and direction is which on the print. My printer uses specific lines added to the GCODE to set the second extruder offset and store in flash: M218 T1 X439.68 Y-0.43 Z-0.38 M500 The numbers for X, Y, Z (in mm) are adjusted to get the proper offset.
