After a long couple days of trial and error of errors I have now been stumped. I have every thing working correctly but one thing...printing. Upon starting a print, the print will home, heat extruder and then begin to print. It will start to print the skirt around the object and then freezes. Some times repitier hose will freeze. When the printer freezes I can not take control of it from rep host unless I restart host. I am using ramps 1.4 with A4988 step motor drivers. voltages are about 0.46 each motor. I have small heat sinks on them with a bit of thermal paste as I figured it maybe over heating but it made no difference. Extruder heats up fine, thermostat reads extruder temp fine and bot homes all of its axis perfect, I do not understand why it keeps quitting at begging of printing. Any insight would be grateful.
