Constant Clogging

So I finally got my printer up and running again after disassembling hotend and cleaning out everything. I was able to successfully print an ABS fan shroud. With the shroud installed a switched back to PLA and made sure to keep the head at 230C durning the switch and then manually extruded a lot of PLA from the nozzle to clear out any remaining ABS. I got a really good 1 hour print after some minor bed leveling adjustments, but then my nozzle clogged again.

My PEEK and nozzle keep getting regularly clogged.

This is occurring frequently, is this a design flaw in the UIltimaker hotend or is this user error?

There are some simular post under the post "little issues after finishing prints"

These may help.

Depending on your quality of material you will be able to adjust the hot end temperature, Ive been using ColorFabb PLA with a range between 195 to 220 degrees C, I tried a test print and used the handy pause at Z height feature in Cura to alter the temperatures and ranged from 220C down to 202C, looking at stringing and bonding between layers and lines, and am printing at about 206C with both the Ultimaker supplied PLA and the ColorFabb ones.

Having said that I am still a newbie and still learning, I don't have any ABS to try at the moment nor the ninja flex but I do like the ColorFabb XT.

Hope you get your issue sorted soon.

Thanks for the reply Izzy, I will check that thread out that you mentioned. I've been using both the Ultimaker Brand PLA and Protoparadigm PLA, both are generally regarded as at least decent. I've found that around 230 seems to work best for them on my printer, though some prints I get stringing at that temp (indicating its too hot), but if I go much cooler I get underextrusion. My room temperature is 54-56 F, so that may also be playing a role.

I may try to add a filament sponge, dust may be contributing to the issue as may be my some component of my extruder driver (my primary extruder doesn't seem to have the extruder drive upgrade installed). I'm am bombarded with school work at the moment and may not be able to disassemble things for another 2 weeks, but I will definitely be compiling info and making a plan of action in the mean time.
