Yes I am using Slic3r. Not sure what you are talking about by Reaction amount but I will look in the software and see if I can find it. I do know that my next thing to work towards is printing solid walls but the windows and doors will need to be open. I want to get his figured out as the next test, although requiring some more modeling (I have stairs to do) it will be its final test as the output is what I got this printer for. Thank you for the help.
