Hi, RepG doesn't work out of the box with Sprinter firmware. I suggest you use pronterface which is available at:
pronterface is [
github.com] and precompiled for windows (without sfact) at [
koti.kapsi.fi] & precompiled for OSX (without sfact) at [
koti.kapsi.fi]
However, you can get RepG to work if you follow this link:
