The issue is that the Xbox power supply only gives you 12 volts at 19 amps max. That is not enough for a printer in regards to current. Most printers use a 25 to 30 amp supply. I even went overboard on my Delta and put a 90 amp supply. You can never supply too much current. The system will only use what it needs. Nut you need to have some over head as well.

You need a better poser supply for sure. An XBOX supply does work, but only so well and for so long. I think this will solve your problems

At the 12v terminals of the a.c. adapter?

So it v sits at around 11.87 and varies. When trying to hit 70 and keep the hotend hot while printing it dropped to 11.8 and triggered thermal runaway.

So have you measured your voltage at the point the problem happens to see if it is dropping?

I've ran my heated bed for a while without issues. Now out of nowhere when it gets to over 65 while printing it will throw a error and pause. I tried lid tuning with no luck. I'm using a Xbox 360 a.c. adapter and this has been the setup for a while with no issues. I believe both the hotend and bed can get up to temp but as soon as it tries to print a error is thrown. The board I'm using is mks 1.3 I believe.
