Fixed it, thanks!
Tho I remove the second extruder, as I havent used dual printing. Less weight to drag around
Didn't want to hassle with positioning the extruders, seems like it's difficult to get perfect height on both.

yup!
Also after around 500 hours printing the PTFE tube was very bad. Actually had the shape of the nozzle, and was black...

I went from smooth to fully threaded having failed completely to get the non-threaded part out of the aluminium bar. The threaded ones do not stick.

that's a really clean heat block :-)
Mine tend to have bits of plastic all over them.

I found that when the extruder Temp was too High the filament could Boil
and get on outside of nozzle and block.
That's when I discovered that nozzles were getting Hotter than indicated at printer's display.
And used digital thermometer to get Actual Temps at nozzles.
(averaged about 15 C error)
Then lowered setting for correct temp.
I'm not saying you are having same problem but someone out there may have that problem ?
It seems that many people set and leave the temp Way too High anyway !Last edited by EagleSeven; 10-13-2015 at 02:40 PM.

I had this same problem with mine when I pulled the extruder tip to clear a clog. The whole block shifted and because loose on the shaft it was screwed in to and returning it to its normal position didnt tighten it any.
So right or wrong, I removed the set screw and pulled the whole shaft out and tightened that into the heating block all the way using a pair of needle nose pliers. From there, I used an adjustable wrench to hold the block while I used a socket to reinstall the extruder tip.
Then I put shaft/heater block back to where I thought it was and tightened the set screw. Then I just re-leveled the bed and it prints good now.
I also pulled my 2nd stepper motor off mine, too. I left the extruder and heat block installed because I was too lazy to pull the wires out of the loom. I also redirected the other fan to blow on the working extruder, too.
Like you, I figured less weight would lead to longer lifetimes on the belts and wearable parts.

Less weight also means prettier prints. Less moving mass means less backlash around the corners. So you can go faster (and turn up your acceleration) and still get a smooth finish. Or so I've heard.
