Small loop at end of job dissfigured

At the top of my marvin there is a loop for a keyring. But on every print it messes up.

I think either it is going too slow and melts it, or it stops at the end of the layer and melts it. There does not seem to be an option for "cool head lift".

Can anyone advise?

Check out the Cooling tab, "Speed Overrides".

You may be putting too much heat into that small area too rapidly. You can slow down the printing by setting the minimum time to print any layer, and/or you can speed up the fan for that small area.

The Speed override would not solve the Problem, as the hot nozzle pumps heat into the print. It is neccessary to move the nozzle away. Other slicer have the option to choose between slowing down or orbit the around the print. In fact this is a very important Feature that should be requested, especially when you are using warping materials as ABS where you must not use a fan to cool the print.

Old post, but 4.0 came out and I've been hoping for this...

I'd like to +1 for an option on the cooling tab to orbit or park for a minute to slow down.

As mentioned earlier, slowing down on its own pumps a lot of heat into small features like the tips of pyramids or narrow towers. Slowing it down doesn't do it- as it leaves the nozzle in contact for longer, just adding more heat to the print.

While an orbit or park can cause drip or stringing issues, this should be up to the user to determine if it an acceptable solution for a print.
