<p>I am converting an old Makerbot Replicator 2 to Marlin Firmware and everything works. The printer heats up, auto bed levels, and starts the print. However, after a couple minutes (usually after the 1st or 2nd layer), the printer crashes and stops. It does not continue printing and I have to restart it again. It crashed for every single print, I have not had any successful prints yet.</p>
<p>Here is a video showing the issue:</p>

            </div></div></p>
<p>The camera was started right when the print started. After about 1.5 minutes, the printer crashes, and the lcd screen freezes.</p>
<p>Here are photos of a couple of prints that crashed:

<p>I have all of my code here: <a href="https://github.com/RosalieWessels/Marlin_MakerbotReplicator2" rel="nofollow noreferrer">https://github.com/RosalieWessels/Marlin_MakerbotReplicator2</a></p>
<p>My models are sliced with Cura and printed in PLA.</p>
<p>I tried hotend temperatures of 200, 210, and 220 degrees. My print speed is around 50 or 60 mm/s.</p>
<p>Here is a sample sliced file that was used:

<p>Thank you!</p>

This will be a simple quick print to get a solid reference.</p>\n<p><strong>Voltages</strong> - Get a Multi-meter on the Regulated Voltage rails, 5V Rail, 12V rail / 24V rail. See if at the moment of crash a voltage rail collapse, the most likely one would be the microcontroller rail, but you may be able to see the problem somewhere else.</p>\n<p><strong>Current</strong> - If possible, measure the current draw of the printer either from the mains or after the AC/DC regulator. Its possible something is going horribly wrong and current limiting.</p>\n<p><strong>Serial Port</strong> - Possibly connect the printer to a PC via its serial port and open a com port. See if the printer spits out an error code at the time of crash?</p>\n<p><strong>End Stops</strong> - Double check that none of the End Stops are accidently being triggered (Although this should not crash the system, it might be part of the problem)</p>\n<p><strong>Verify Sensor Readings</strong> - Check all end stops, check the bed temperature readings, check the nozzle temperature reading. Maybe a sensor has failed and is causing the controller to crash out.</p>\n'}, {'answer_id': 14175, 'author': 'Trish', 'author_id': 8884, 'author_profile': 'https://3dprinting.stackexchange.com/users/8884', 'pm_score': 1, 'selected': False, 'text': '<p>I see a couple likely culprits for a hardcrash like this</p>\n<ul>\n<li>problems with the power supply.
