I have an he3d delta running marlin.
everything seems to work just fine, in that homing is good, and when i start a print the carriage moves down from home to the 'start position' of 5mm above the build plate perfectly.
the start of the print (raft and first layer) printer perfectly, but when it moves onto the second layer, it doesnt move up at all in the z axis. so it just starts to plow through plastic and make a mess.
any idea why? im fairly new to arduino and marlin too, and im pretty sure its a firmware thing..maybe slic3r issue? so if there are any variables anyone wants to see, or any settings. just let me know!
thanks in advance for the help guys!
