Bed wires dislodging

Is there a way to reattach the bed wires? I am using a crude method using kapton tape to keep the wires adhering to the bed. This is not a solution.

The wires are being held on with some red stuff. When applying slight pressure I get contact and the bed heats up.

My prints have been shutting down because the bed temp drops. It due to this loose connection

I also found that my old version of Repetier Host is printing but latest version of Cura will not. Strange.

I was able to set Repetier for PLA no heated bed and it worked. Cura, setting the bed temp to 0, still produced the error, mintemp

Repetier is going strong. I taped the wires down temporarily and my bed is heating. But I need to somehow affix them to the bed better.

Any ideas, solutions?

Yes it looks exactly like http://www.amazon.com/Permatex-Sili...0840804&sr=8-5&keywords=permatex+ultra+copper.

You are going to have to carefully scrape off the silicone and resolder. Then apply the Ultra Copper stuff. It is a bit difficult to solder to the flex PCB trace. If there is no metal trace exposed you will have to gently scrape the insulation layer off with an exacto knife.

 

You need a really powerful soldering gun to heat up the PCB enough to solder onto it. No matter what I did with my 900W pen iron it wouldn't stay soldered.

R3D might sell you a replacement if you ask nice

 

My Ultimaker is having temperature problems. I get a mintemp or maxtemp error.
If you get one of this error messages it means that your Ultimaker is not able to register the temperature properly. A ‘mintemp’ error means that the Ultimaker thinks the temperature is too low (< 5C) and a ‘maxtemp’ error means the temperature is too high (> 300C). In both cases this is most likely caused by a loose connection of one of the wires. Therefore, please check the connection of all the wires on top of the printhead and the connection of these wires on the electronics board. It is recommeded to disconnect them and plug them in again to be sure that there is a proper connection. After having turned your Ultimaker on again, check if the error message has disappeared. If not, you can get in touch with our Support team for further help.

I keep getting this error using CURA now. MC also stops during printing. Repetier seems to stop once in a while. I am able to get my bed heating up by putting a bed clip I found on Thingyverse. I wonder if it's a short in one of the connection wires and it is intermittent because it is not always shorting out. When it does short, the print stops with an error.

Where on the Extruder is the wires responsible for moving x, y, z, axis. When I do have an issue, I notice that I am able to HOME, but moving LEFT or RIGHT or UP and DOWN does not work. But manually moving it to the centre then homing. it goes HOME.
I cannot continue even if restarting the print program until I reboot.

What would cause that? I reboot and it goes back to normal. Printing away until I start another print and all hell breaks loose. It's like a virus, stricking once in a while. Fustrating. What happened? I was printing everyday no problem. Did a few updates and one day, it hit, and has been hitting since.

Could the USB cable be at fault?

Could it be the Adrino Software version? I have the latest. 1.7 or something.

Could it be a loose connection on the Extruder or RAMPS board? Which wires to test, thermister or other? I moved the wires around and did not notice any changes or even interruption. The wires seem sound.

 

Regarding replacing the thermister, is it a matter of just soldering the wires to the two end and your done? I can get a thermister near me. Are they all the same?

 

Did another print using an old version of Repetier host and this is what I saw during printing.

Strange rise and dip in the temp at one point. Your right, Seems as though the thermistor is going in the print head. Not dead yet but showing signs of anomalies.


So far it's still printing but after 6 months of use, things are starting to fail.

Oops, down spike
