Hello everyone.
This is the first 3D printer I'm building and I've done a quick set up of Marlin on Arduino IDE,
I just need a little help, nothing has blasted on fire at the first start (which is very good), I've encountered the following issue,
None of the steppers, after moving them via the "move axis" cmd, will go back, they only go forward.
I'm using a RAMPS 1.4 over an Arduino Mega2560.
is there any command I've forgot to define in Arduino?
thanks for the reply.
