I've just set up an e3D v6 print head on my ultimaker original, using the same thermistor, heater cartridge as came with my UMO. I've wired up an always on fan to cool the heat sink, and two side fans that come on as usual when printing.
I'm starting to run a couple of test prints and have run into a couple of issues.
The temperature reaches 200 very quickly (about 1-2 minutes) however then takes about 10 minutes to reach 230 degrees. I'm trying to preheat to 250 but it then won't go any further past 230.
I'm not entirely sure what might be causing this but thought that it might be the always on cooling down the print head too much. I also read a post from someone having similar issues (https://forum.e3d-online.com/index.php?threads/hot-end-hovering-below-target-and-never-reaching.281/) however, it refers to a page on PID autotuning. I'm not entirely sure how to run this, and how to modify PID settings through Cura or any othet software.
Any help/ advice would be much appreciated.
Thank you!
