Edited: I no longer have a cooling issue…
Also, here’s an update on the upgrades I have done. I would recommend that you print the long channel and 15 of the connector links for the X-axis. In the photo, I have fishing weights holding the assembly down while it prints, in an attempt to break-in the links so they lay flatter over time.
Which Cura version and what do you set in the cooling config?
It’s Cura 14.07 (came with the printer). And the current settings: Advanced/Cool 10 sec, Enable cooling fan, … and im an idiot…
Looking through the settings, and opening Expert config, i see all the other cooling options. They include fan speed min and max settings.
