Max Temp Error with 3D solex Hard Core [solved]

Posted (edited) · Max Temp Error with 3D solex Hard Core [solved]

Hey Guys,

Just bought my first Hard core from 3D Solex, but when I install it in my UM3E , I get the Max temp error every time.

I've tried, the normal method to change cores, and I've tried doing it when the printer was off. None worked....

HELP?

If the originals PrintCores are working, and the ones from 3D Solex aren't, it seems to be a problem with the 3D Solex cores.

If you use a meter to measure the resistance of the PT100 should be slightly above 100Ohm (100Ohm @ 0 degrees C). The pins to measure are the 2 right pins on the print core.

A value of infinite will cause the problem with the MAX_TEMP_ERROR, and might be just because of a broken cable.

I measured 110 Ohm on the gold pads so it's not a cable problem it seems, and yes the original core works fine.

That's weird then. The only one thing I can think of right now is cleaning the pads with a little bit of alcohol because of grease or other stuff preventing the pads from making a good contact.

Found out! There was a short circuit between the PT100 Contacts and the small connector (some solder) that is present on Solex only. I don't know why they put this connector but, they had to put the wire too close to each other... not a good design (layout speaking). Anyway, it's working now. :)
