Topic: Help me please, Over extrusion?

I apologize for double posting but no one was replying in the other area. Hey everyone so I've spent about a week correcting the tension of belts, aligning pulleys, leveling the bed, and making slight tweaks to the firmware settings and everything is going well, well almost everything. I cant seem to find what this is called but when I print some small thin tall objects this occurs(see pic) you can notice the one in the back printed fine because I printed two on the bed simultaneously which allowed it to take a break after each layer to print the other cylinder. But when I printed just this one it basically mashed the plastic of the cylinder down. everything else prints great and I am almost positive the layer height is exactly .2 mm, as it should be, when measured. Any help is appreciated.

Have you tried reducing the speed of small perimeters in slicer?  If not , you might try that.

Re: Help me please, Over extrusion?

Rather than over extrusion it looks to be too hot to me. You need to slow down to maybe 15mm/s and if possible print more than one of these at a time or add other prints to the job as well. The Extruder is staying on that small portion too long and not allowing it to cool enough for the next layer. So it is moving the previous layer around as it lays the next layer.

Printing since 2009 and still love it!

Thanks guys! I usually have no problem printing multiple I just wanted to figure it out for the future if I print any large objects with thin structures like this. So you're thinking I need to slow it down for prints like this, got it.

Cura Host works great just like it's slicer. You might have to play with your Z offset a bit though.
