Spent the last two days trying to adjust the settings in Matter Control. No problem extruding, but it's like the arduino board that controls this thing is one that flew over the cuckoo's nest. This image shows sticking issues, but that is mainly out of I've-been-trying-to-print-this-circle-for-two-days laziness. It won't even repeat its designs. What occurs when I print: loud grinding sounds from the y-axis, but no contact with the extruder to cause that sound. The z-axis is level. Similar results with slow or fast speeds. The printer begins each time by drawing shaky horizontal lines for the first 5 minutes of 15 minute print before making about 2-3 lines of circle shapes, each on a different portion of the y-axis. It looks like this is a connection issue with the y-axis, but I don't know where to start to fix it. I am a novice on the most basic level, so this is beyond me. PLEASE HELP!
