Similar to printrbot´s version but this has a slot instead of a flat contact surface
Anyone tried this?
-
Try to put a box over the machine to keep the heat inside, it worked for me
-
I received a new replacement machine from 3D verkstan yesterday, excellent service !!
Loaded it with ABS and started to print. Really good flow trough nozzle before printing.
Not that good flow 8hours later before second print.
String length was aprox half
Problem or not, it just a observation for now
-
Thanks for reply!
1.First try and fail after nozzle change was at 245C
2.All prints was done at 40mm and 0.12mm
3.Temperature sensor is changed 2days ago
4.Isolator is changed and I tested to slide it on a piece of filament it was no problem
-
Last print failed..:-(
Suggestions?
-
Took head apart this morning without finding any oddities. .Spacer was well seated towards the nozzle with no gap.
Installed latest firmware.
Another issue is bad bonding between layers.
Doing another try now.
Nozzle temperature,now att 260C,looks stable when machine is running.
Feed motor is reversing with fast reverse and slow forward. Not retraction with fast revers and fast forward.
-
Where can I download newest firmware?
-
Thanks, lot of good input!
As I see it´s too mutch friction in the hotend. Tried to manually push filament through without the tube and is very hard. Have to check if there is a gap between nozzle and teflon that can cause this.
-
Now I have change coupler,hotend,tempsensor,filament. And it worked fine for the first 10hours, after 10hours it appears to be The same problem.

Not far from göteborg

Thanks, I will check the coupler.
Any other ABS suppliers ?
-
Thanks for answers,
My filament is between 2.8-2.9mm
I have about 200h of abs printing with 50% waste,.with worse result at the end
Problem is bad flow trough hotend.
Think I will try to change filament

Material get stuck in hot end or feeder dont feed enough or filament too soft, hard to tell what .
Maby a combination

I added 0.2mm to the rib and it went well :-) Tanks !
-
Thank´s, as I print in Abs it´s a little tricky to get it to stick and specially this little piece sticking out, thats why I addded these ribs. I tested with a flat 0.3mm surface under the piece sticking out but thats also not visible in layer display
-
Thanks for reply!
Option no 3 worked! , to have smaller wall thickness than the rib. But I want to have thicker walls..
I want to avoid more infill cause I will do a lot of this parts and as it is now it will take over 20hours
-
,
Beam in the middle of the part is missing when changed to layer display..? see picture.Some one knows about this?
-
How to change support fill amount at a specific height?
ex. to change from 30% to15% at 5mm from bottom..
is there a plugin for this?
Best regards Mats

I´ve only used Um2 for about 3 weeks now.
I think cura is a great program, easy to use/learn.
Some suggestions:
- implement auto off in cura when program is finish as an option
- Auto save position of part when reloading model
- Change the noisy fan
- 2 extruders, one for supportmaterial to get better support=flatter and smoother underside? just dreaming on last one but maby it is possible..
:-)
-
No filament for outdoor use developed? it´s common to mix in uv stabalizers in plastic industy..
-
Someone know if there are anyone selling UV resistant filament ?
Best regards
-
I use a 2 year old Dell workstation laptop with Intel I7, win7 pro and 16GB Ram. Cura slicer use only 3GB and about 10% cpu..
It´s not a big problem but I often wondered why
-
Ok, tried something like that yesterday, I have to try again.
Thanks a lot.
Why I've decided to ditch my UM2 (+)
