Custom Reprap Sizing and Axis Questions
December 12, 2014 05:28PM
Hello RepRap Community!

I'm new to Reprap and am going to be building a custom Reprap, but I had some questions on sizing and the use of axi. To my knowledge RepRaps aren't limited to any particular build plate sizes, obviously if I want a heated bed, which I do, I am limited to rather standard sizes for a heated bed, but for different sized build plates apart from say the prusa, where would I tell the 3d printer that the build plate size is different? The arduino code? Slic3r? Also, does RepRap have to have the y axis moving back and forth as the build plate vs the carriage and extruder moving in the x and y, axi with a makerbot style z-axis? Are there any advantages or disadvantages with moving a build plate as the y-axis? Thanks a lot!

In your firmware you can set the max lengths like this in Repetier:
#define X_MAX_LENGTH 200
#define Y_MAX_LENGTH 200

In Slic3r you can also use a custom round or rectangular shape, or set a custom bed shape like I did by importing a STL. See attached.
