Thanks!  It is a firmware problem. I had the extruder at 250c and bumped it up to 260c. It must have thought something was wrong and it set the temp to 0c. Unfortunately, it keeps printing. I made a quick and dirty enclosure with a few pieces of cardboard and then was able to get up to 110C for the bed and 255c for the extruder. So I guess I'm building an enclosure and will also upgrade the firmware to Marlin.

be very careful to maintain proper temperature inside the box as that could lead to elephant foot artifact (melted object at the hotbed).

<p>I have the Monoprice Select 3D Printer (i3 clone). I'm trying to print ABS. I set the temperature to 230°C for the extruder and 110°C for the bed. I can see the printer warming up to those temperatures and then when it gets there the bed and extruder set temperatures reset to 0, and the print does not start.</p>

<p>I pulled the ABS out and went back to PLA and printed a part without any issues. </p>

<p>Any thoughts on what the issue might be?</p>

Does it shut down the temperatures before reaching the demanded values? Or close to these values? Not many heat beds reach 110°C due to bad connectors/connections, thin wires or lack of insulation at the bottom side.

It looks like the problem is that it shuts down before reaching the 110c.

I was playing with the extruder temperatures. I was at 250c and bumped it up to 260c. It must have thought something was wrong and it set the temp to 0c. Unfortunately, it keeps printing.

I made a quick and dirty enclosure with a few pieces of cardboard and then was able to get up to 110C for the bed and 255c for the extruder.

So I guess I'm building an enclosure :)

Most firmwares requires a decent increase in temperature every few seconds.

if you use Marlin then in the source code you can extend thermal shutdown timings.

what to check:
**check every single connector to eliminate any fiddling or play - risk of fire !!!**

**if any of wires goes hot - double check connections, replace wires/connectors**

1. note temperature change (how many seconds/degree) on the hotbead
2. then increase voltage on psu (probably you have a led psu - so there is a small regulator next to the connectors)
3. validate if that help
