<p>I just set up a refurbished <a href="https://www.monoprice.com/product?p_id=29417" rel="nofollow noreferrer">MP Select Mini V2</a> and tried to print the test file included by the manufacturer, <code>cat.gcode</code>, from the included SD card. I printed in PLA (I think; the unlabeled sample included with the printer) at the default extruder temperature, 190&nbsp;°C. The print bed was set to 50&nbsp;°C.</p>

<p>It appeared to print the raft fine, and then a couple of layers of the cat. At this point I walked away, and when I came back a few minutes later here's what I found:</p>

<p>The raft is still stuck to the bed, but the layers of cat that were printed fell off the base and onto the floor. Here's what I picked up off the floor, (next to the detached raft):</p>

<p>The raft was stuck on the bed just fine, so I don't think it's an adhesion issue. The bed and the desk the printer is sitting on are both very close to level (things don't slide or roll off). There's no breeze and I'm certain nothing bumped or touched the printer while it was running.</p>

<p>This is my first attempt at a print so I obviously have no idea what I'm doing. I'm planning to set up a camera to record the next attempt. What other troubleshooting can I do? What is the likely cause of this problem?</p>
