Hi everyone. I had a couple of print fails where the printer just stopped. Then I noticed temperature fluctuations on the nozzle and bed. Now nothing is heating and the temperature is reading 0 for the current bed and nozzle temperature. Looks like something has failed can anyone point me in the right direction?

Or read the forum, try this that I write about, had the same problem and now is totally fixed https://www.forum.makertech3d.com/forum/general-discussion/fix-for-temperature-fluctuation-and-other-issues
Check that there's proper cable relief, so when the tool head is moving the thermistor at the contact point isn't and is fixed further up the cable. That should give a more reliable temp reading.
Also check that there's a gap between the heater block and heatsink, the hotend should easily be able to reach temps of up to around 250C.
Very likely an issue with the thermistor. Try removing it from the heated bed or hotend and reinsert. If that doesn't work the thermistor may need replacing. If you're still within the 1 year warranty we can get one out to you to, just email us at info@makertech3d.com.
Anyone? My first thought was a power issue but the 0 reading at room temperature makes my think it's some sort of control issue. Is it possible that there is a glitch in the firmware or is does the fact that it looks like a progressive failure point to a component going down, possibly on the control board? When you set it to print all the target temperatures come up on the screen OK but nothing heats up.
