Temp Problem Hard to Fix
Posted: Wed Feb 20, 2019 3:11 am
Hi Everyone,
I know there are a ton of topics on this subject, but it's tough to piece them all together to see what actually worked and what didn't - so my apologies for creating another one.
Problem: Temperature fluctuation on the hotend +/- 7 degrees C when set in the controls. A little more extreme when printing (~+/- 15).
Model: Single extruder - not sure which revision (Purchased in Feb 2016).
Slicer: Simplify3D
What we've tried:
-Replacing thermistor
-Replacing V4 Heater Cartridge
-Removing the wire bundles from the harness, measured each temp related one back to the Rambo board (while moving it around) and they were all ~1 Ohm or less.
Not sure how to upload pics, but here are the links to the pics of the Consol and the printer - sort of taken apart..

You can see the fluctuation in the extruder temp. It's slight, but it won't allow a good first layer, causing the entire print to fail. You'll see in the 2nd pic we have the hot end out of the bracket, but that was just for testing purposes. New thermistor measures 130K Ohms.
We have successfully used these settings and made this print probably 500 times - so I don't think the settings are to blame. We just upgraded to the newest version of Simplify3D - but we were having some issues prior to that. We print via USB cord.
That's about all I can think of. Hoping someone can help. Thanks in advance for suggestions and assistance.
