Hi!
I am building an Lasercut Mendel with E3Dv6 hotend and the frame from Think3dPrint3d. I did print all .stl with my 2013 Mendel. Most parts I bought from various sellers, also the GT2 pulley(16 tooth) and a Gt2 belt. Please where (in the config_h ??) I have to modify the values. I have downloaded the Marlin version Form github of T3P3, for Ramps 1.4 with arduino mega.
