Topic: Temperature is Reset error

Hi Everyone,
I just installed the E3D with the MK5. I also uploaded the new firmware with the .22 Arduino version (couldn't get the newer prepackaged version to upload). Did an 8 hour print yesterday with no clogs which is fantastic. Today is another matter. If I print for about 5 minutes, it will stop in mid print and both the bed and the E3D begin dropping in temp. The light on the Repetier software buttons are still on which makes me think the software isn't automatically shutting it off. Then it starts to spit out the error "Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)" and it just keeps repeating that until I close out of the program.

Could it possibly be a power supply or wiring problem? I installed a new power supply (SUPERNIGHT 12v 30a Dc Universal Regulated Switching Power Supply 360w). However instead of the lights flickering every so often like they did with the old power supply, they flicker very fast when the E3D heats up. I also think the stock bed takes longer to heat up then before. Since I did such a long print yesterday, I figured it was fine, but maybe not.

I'm not sure if it matters, but here is my setup:
SD3 with ATMega 644P
Cannibalize AWG connectors from an old Solidoodle extruder
Supernight Power Supply
MK5
Stock bed heater
Plexiglass enclosure
Mac Repetier/Slic3r


Any help would be greatly appreciated and thanks in advance.

Re: Temperature is Reset error

Check your connections for the hot end and thermistor, especially if you cannibalized the connectors.  I had this issue, so I just replaced the old ones with new JSTs and it's flawless now.

Re: Temperature is Reset error

I don't think it is due to the power supply at all. The lights would continue flickering if that were the case. If you have temp drops, here are some basic troublshooting tips:
-verify the firmware change stuck. If it did not, the max temp would shut it down shortly after the job begins. I ran into this personally when I dragged my feet on the firmware. But I do not think this is the case since the bed temp drops as well.
-trace the wires to the board...they may be loose.
-if you have not yet, add a fan onto your board. Those steppers can get really hot...I would recommend this wether it is the culprit or not

Re: Temperature is Reset error

Thanks for your help. I believe the firmware must have stuck since I can now heat my hot end over 200. I run it at 245 for ABS. The lights do constantly flicker as long as the E3D is on so that's why I thought that maybe something is failing because the power supply is working too hard.

Are you recommending a fan on the actual board itself or the stepper motors? I've seen mods for both. I was hoping to use the old extruder as a backup but the connections do seem a bit flakey. I had to re-crimp one of them. I guess I will have to make a solid commitment to the E3D. It's just strange that I went all day yesterday without any problems.

The Supernight PSU has a vref you can adjust...it's right next to the green led. I had to turn mine up by a 1/32 of a turn. Another thing is to daisy chain all possitives together and all negatives together...this will give you a constant and steady flow of power...http://i.imgur.com/c2cN81u.jpg
Sorry to all for the oversized pic.
I suppose it is a possibility that you are not giving it enough power and the printer shuts the heaters off as a failsafe (?)...maybe someone can confirm or correct that, though.

I have a 40mm fan blowing directly onto my board about 1 1/4" away. That way it is directly on it and all airflow hits the entire board. Some use 50mm fans, but I stopped having layer shifts after installing it.

I saved my old hotend and crap acrylic extruder as well for the same reason. But after a week, I noticed the E3D truly is a superior design.

Re: Temperature is Reset error

Azerate, I'm assuming you took the acrylic cover off the top of the board so there is nothing blocking the board, right? I will try the fan first before I swap the connectors. Since I don't claim to be a wiring genius, I'd rather not open it up if I don't have to. Your theory about the printer shutting down actually sounds consistent with the symptoms. Is that possible?

Re: Temperature is Reset error

Ok, so I turned my printer on this morning and the first thing it does is heat up the hot end all by itself to the point where plastic is smoking out the hot end. I didn't even turn it on so I'm thinking it's a wiring problem. Does that sound right? If so, I'll have to rewire everything and get rid of the old connectors.

That does not sound right.  I can't even think of a scenario where that is possible.

Re: Temperature is Reset error

Only thing I can think of is the thermistor slipped out of the groove.

Re: Temperature is Reset error

He would have had to at least call for heat on the hot end.  It doesn't sound like that is the case if all he did was turn it on.  I presume that to mean plugged it (the printer) in.  If indeed it overheated after turning the heat on to the hot end then yes it's a thermistor issue.

Re: Temperature is Reset error

Yes all I did was plug the power supply into the power strip to turn on the printer and the hot end uncontrollably heats up to the point where it is burning the plastic. So it doesn't even stop at the set firmware temp. In fact, the computer with repetier is not even turned on. Just to see if it was the wiring in the E3D, I swapped in the stock hot end and it too heats up uncontrollably. That would only mean that the problem exists from the original wiring to the board, the board, or the power supply. The only thing I did to the original wiring was splice in the E3d fan into the original fan on heat sync of the stepper motor which I read was what you should do to keep it on all the time. Does this mean my board overheated and the heater is stuck in the always on position? I did an 8 hour print with no problems the day before so maybe I burned some it out? That's really the only thing I can think of. I did not have a fan on the back of the board as the soliwiki for the E3D did not mention this was a necessity.

I'm kind of at loss now so any help would be greatly appreciated.  I think my next move would be to replace the board. Any suggestions for minimal wiring?

Re: Temperature is Reset error

Check then double check that you don't have something touching any part of the board that could be causing a short.  I doubt your long print job is to blame.  Make sure it is plugged into the correct pins and that you didn't mix it up with pins that are always on such as fan or LED pins.

Re: Temperature is Reset error

Thanks everyone! That was definitely it. The two problems together were causing the extruder to freeze and overheat uncontrollably. Not having a fan on the board would cause it to freeze mid print. When I took the stock acrylic plate off the board, one of the small metal spacers fell perfectly out of site causing a short in the heater. I found and removed the spacer and set up a table fan to blow directly onto the board and now it prints perfectly.

I will make the fan situation more permanent now. Thank you all very much for your help. I couldn't have solve this without you.

That's what we're here for.  Glad you figured it out.

Re: Temperature is Reset error

Hey gang, I am getting the same error but on a day old, un-modified SD4. I ran one 30 minute print just fine and dandy and then, after about 30 minutes of down time set up to run another but got this issue. I have noticed that there is a fan on the left side of the extruder assembly that never seems to be running- could that be related somehow?
