Yes the machines had marlin since day one.

the settings in config.h are identical to the old values; I manually edited them of course, like accels, offsets, servo angles etc... All of those values are copied over into the new marlin firmware I downloaded.


I will try to figure it out and monitor it for the next few days before I go ahead and get you the files to debug. It might be something so stupid and I will be embarrassed :P
