Luckily i'm a tinkerer and don't mind getting my hands dirty!
just didn't expect my first problem would be forcefully break open my new 700 dollar machine.

But a first for every thing, right!

Super happy you guys helped me!

LOL, 3d-printing and fix 3D printer are totally different thing.

The people who are trying to profit off those that dive in without research.

Really anyone who has been printing will tell you it is touchy and not for those who just want to things to work.

I heated the first nozzle to 240C and let it heat as must as it could.
Then pushed a peace of filament in and removed the blocking.

The second nozzle is a little bit a casualty of war.
The temp sensor connector broke off i first have to fix that before unclogging it.

what a trip to fix this mess!!!! How said 3d-printing is easy LOL

[UPDATE]
Looks like the second one is clear to.
Bit need to make a better fix to the temp sensor connector.
I "Soldered" the wire to the connector, but the contact is now touch sensitive.
I will re-build the printer tomorrow and do a test run to see if it works again.

What upgrade do you guys recommend for this **** printer?

Check Carl's instruction on #17 above. After remove the thermistor and heating element, I usually bake it in oven at 392F (200C), use tools to handle hot item and avoid get burned. The printer came with a metal stick that can push into the throat, you can push the melted filament out with that.

Okey finally got it out.
I've cut the filament just above the nozzle start but still i could not move it.
Finally wedged a screwdriver behind it and pride it open.

My happy feelings of owning a 3d printer where melting away by this problem.

Now the cleaning begins.
anyone some pro tips?
The filament is sitting in the nozzle "neck" tunnel(second pic)

The filament in the white PFTE tube on the top of the cartige is preventing the drop-in cartige to tilt out. and you can not get the filament out because the bottom of the filament is stucked. If you can cut the filament in the middle though the opening after remove the fan, you can take out the top half of the filament from the top of PFTE tube. then you can tilt out the drop-in cartige and take it out. You can then clean the rest after you take out the dropin cartige.

I know it has to tilt out when holding the black handle.
But i've even used a screwdriver to try to move the assembly.
But i will not move.
It's stuck in there and i'm afraid i'll break something.

If you cut all the tie wraps holding the wires to the extruder frame you just have to press down on that spring loaded black handle and the entire hotend assembly will tilt out towards the handle and fans. Leaving just the motor still mounted. You don't even need to remove the fans as they are part of the hotend assembly.

Once it is tilted out and removed you can see ho to remove the actual heated part by just removing the nut that secure the feed throat to the heat break. then the hotend and feed throat slip out of the heat break and you just need to remove the thermistor and heater core. Then you can use a torch to head the metal parts enough to burn out the filament.

Once you use the release handle that is black with the springs under it in your picture the image below is what you should have except with two hotends in one heat break and no broken heater wire. The feed throat and the nut holding it in the aluminum heat break are just behind that finned heat sink in the image. Take that nut off and the feed throat attached to the brass heat block will slide out of the aluminum heat break.

Another stolen image from another thread.

all you need to do is to cut the filament so that you can take it out from the top. you can clean the rest after you take out the dropin cartige.

I got of the fans. But i can not reach the filament because of the pcb.
But there must be a way so i can lift the handle and remove the block?
Why can i not move it?
I heated up the nozzle to push the filament as far as i can. But still the block stays in place!!!
I will not move and i cannot get to the filament to remove it...GRRR (i'm starting to turn grey)
ps i also already removed the fanbracket

Take out the screw that mount the fan, and remove the fan, you will see what's going on inside your hotend (Actually the extruder gear), you might be able to cut the filament or pull out the filament from the small opening. (See the attached picture that I steal from another post in this forum)

As long as the filament is broken right at the top of the throat then you just press down the black release handle and the entire hotend fan assembly pops out. Then you can look at it to see what needs to be removed to make it heat safe.

I no longer have an XYZ machine so I can't supply a picture of what I mean. Post an image of you hotend from over head and I will mark what I mean.

but how do i take it a part?
the heating box/assembly will not come out of it's cradle.

is there a hidden screw or something?

As a last resort you could take the hot end apart. So you only have the brass heat block and steel feed tube. Remove the thermistor and heater as well. Then using a torch you can heat the metal parts and burn the filament out several have done it here in the past.
