if you are interested in 3D printing, you cannot afford to miss this post, today, i will show you a step by step instruction on how to print dual color models with geeetech prusa I3 pro C.

Before reading this text，please make sure you have already read the set up guide of the version of 13B single extruder and you can use it to print 3D models. If not, please learn how to operate the single extruder. Of course, you can take this one as the single extruder version to start.

First, you can adjust one extruder to make it parallel with the surface of the heated bed in (the same way you level for the single extruder) , click the button of Z home to adjust the distance between the nozzle and the heated bed, make sure the vertical distances of the nozzle to the four corners of the bed are the same.

Then, you can adjust the distance between the second extruder and heated bed by adjust the screws, as shown in the following picture:

Loose the screws, you can adjust the distance between two extruders and heated bed.
