Posted · Upgraded 2 to 2+

I have a 3 and a half year old  Ultimaker 2...    in the last few months I was having more and more trouble with under extrusion, layer adhesion (on ABS), and nozzle clogging..

 

It was the nozzle clogging that finished it.    Usually I could clear things with the atomic method.. but I finally got to a clog that would not clear.

 

So I disassembled the print head and found that it was  so burnt inside the nozzle that it explained why I could not clear it.

 

Unfortunately I broke the temperature sensor while taking things apart.. and since I figured it would take about as much effort to replace that than to do the extrusion upgrade, I went with doing the upgrade.  Figuring I'd get extra benefits from having a 2+

 

Wow.   The upgrade was easy -- took about 2 hours... and the first print off of it was perfect...    It's like a brand new printer now.

 

I also like the firmware on the 2+ -- especially that it asks for the material type before you insert the material in a material change..

 

And I can't wait to try out the different nozzle sizes.

 

I'm also thinking I should never again get into a situation with an un-clearable nozzle because I could always just remove the nozzle and clean it chemically.
