[Ultimaker 2 bubbly extrusion]

If the filament absorbs water, it can go to steam during extrusion and cause this. What type if filament are you using, how old is it and how was it stored and for how long?

Do you have other filament you can try?

 

its color faab xt and i just took it out of the package it was stored in for 3 months

Ultimaker 2 problem:

[Ultimaker 2 over extrusion]

so when i print with my um2 it seems to slow down momentarily then spew out more plastic than normal.it causes bulges and unevenness any tip? also the plastic beads up and looks like little drip marks instead of one solid line. the extruder is not clicking or skipping.

 

[UM2 Extrusion problems (again ultimaker has the worst customer support ive ever dealt with)]

How did you unload the filament? If I use the change filament procedure it results in a very fine thread inside the Bowden tube as the unload is performed at a significantly too high temperature. This thread is hardly to not visible by eye but blocks the filament flow as the clearance between Bowden tube and filament is extremely small on the UM2. So, I recommend to clean the Bowden tube as you feel some resistance when inserting filament manually.

About UM support: I don't understand how they could keep customers waiting for an answer (not for a solution) for up to week. Something is still quite wrong there. I can only guess but I think it has something to do with their ticket system. It upgrades every ticket by two levels in urgency from day to day. I think there is something like 6 different levels which means that after three days latest every ticket has the highest priority. This must be very difficult to deal with for the support people. So, I recommend to UM to switch off this urgency upgrade and let the customer choose and eventually upgrade the urgency level.

 

ok. ill give it a try. any other ideas as to why its clicking?

 

[UM2 Extrusion problems (again ultimaker has the worst customer support ive ever dealt with)]

so since ultimaker isnt responding to my emails i thought instead of paying money for a new nozzle that id try to unclog mine. so i took it all apart and help a propane torch on it until and the pla had burned away. i looked through one end and could see light through the tiny little hole in the end of the nozzle. i put it back together and what do i get? under extrusion and the little click/skip on the bowden extruder. i took of the tube and tried to manually feed it and i felt the it wasn't going through with as much ease. i might not be hot enough or the nozzle is screwed. what weird is that it will print fine for a bit but then start clicking. and when i extrude filament it doesn't just string out of the nozzle, it beads up on the tip. PLEASE HELP!

 

[Hot end for ultimaker 2 (ultimaker wont respond to my emails, AGAIN!)]

This is in flux (this is changing).

This item was incorrectly priced around 95 euros but that includes a bunch of other parts like the heater I think. So there is now a newer price around 45 euros and this should be listed on the server as a purchasable item. Soon. Here:

https://www.ultimaker.com/t/spare-parts

But it's not there yet.

I recommend you fix it. I've had some very nasty clogs but almost everything burns at a lower temperature than brass melts. So take the nozzle completely off your printer (you have to anyway if you buy a new one) and put the whole thing in a gas flame for about 20 seconds at a time (don't want to melt it) until everything is burned to ash. Then soak it in acetone for an hour and then clean with the atomic method.

Did you try the atomic method by the way?

Meanwhile I'll PM someone who might be able to sell you the nozzle directly.

 

how do i take it off?

 

[Hot end for ultimaker 2 (ultimaker wont respond to my emails, AGAIN!)]

so i want to buy a new hot end for my ultimaker 2 because mine which i stupidly decided to print woodfill on is clogged and nothing is coming out of it no matter what i do. it took me 2 months for ultimaker to send me a quote for a new hot end. i replied asking if i could pay via PAYPAL but i still havent heard back from them. so does anyone know of any hotends that are compatible with my printer? i dont want to give money to a company that doesnt have time to respond to a dissatisfied customer's email.

im honestly thinking of tossing my UM2 off a bridge and getting a makerbot because i know anyone's customer service is better than the service i am getting now.

[Can't reach ultimaker support]

So I've emailed ultimaker 2 times over the last 3 weeks and havent heard from them I called but the operator said the number wasn't in service. I need legitimate help with your product that I spent money on and you aren't available to help me. What gives?

Please let me know if there is a reason I have to wait weeks on end get a response from you.

[UM2 Hot end temp is zero (manually increase)]

Are you sure?

When you first start a print, the 'Tune' menu is going to show the nozzle temp as 0, while it heats up the bed. Only when the bed is mostly heated does it turn on the nozzle heater. This is to avoid leaving the head sitting hot for a long time and cooking the filament inside.

well that explains it thanks ive been cranking it up as soon as it starts heating the bed. i hope i haven't ruined anything. thanks for the quick reply!

 

[UM2 Hot end temp is zero (manually increase)]

so whenever i need to print something i always have to manual enter the print temp by going into tune the temperature and turning it to 210 which is what i print pla at. the printer remembers all other settings like plate temp etc. but it wont remember the hot end temp. i always have to start the print then go in and increase it to my desired temperature. please help?
