I've noticed that the Bowden tube is also jumping and separating from the hot end isolator coupler.
...
This should definitely not happen and is an explanation for the extrusion problems...
You can try to cut off a few millimeters of the bowden tube (with a sharp knife) - so that the bite marks 'move' to another position.
The bowden tube has to be firmly attached before you go on with further investigations... (IMHO)

Mit verkabselt meinte ich nur, das auch in einer Schicht verschiedene Filamente verwendet werden können. Muss man sich Vorstellen wie wenn das Leitende Material wie eine Verkabelung im Druck integriert wird.
...
Mit ein bisschen Software-"Tweaking" (z.B. ein Cura-Plugin) wäre so etwas wahrscheinlich auch mit nur einem Extruder möglich - aber das wäre mindestens ein Materialwechsel für jeden Layer, in dem die "Verkabelung" enthalten ist.
Ich kann mir nicht so recht vorstellen, dass das Spass machen würde...
Mein persönliches Fazit: Ein Ultimaker 2 ist für so einen Anwendungsfall leider nicht geeignet.
Für einen Dual-Extruder Drucker wäre das aber bestimmt ein interessantes Forschungsprojekt...

the professional thing would have been to send out an e-mail to all of your customers and tell them what has happened as i explained above and have something ready in advance.
...
Unfortunately such an e-mail would only reach customers who have bought directly from Ultimaker.
There are plenty of resellers out there selling Ultimakers. I'm pretty sure that the Ultimaker store itself has never heard of me or my e-mail address...
For sure - one could inform the resellers and requesting a forwarding of informations - but that would be a request...not more...
Instead - customers (at least that one who care about...) _will_ ask support for the second extruder kit. Offering a modified fan shroud (as apology) in these cases is a reasonable idea (i think...)
...just my 2 cents...

I've just uploaded the "Tinker"-Version of the 15.01 Release.
You can download it from GitHub if you want to take a look.
This is the first attempt of the two-page printing screen (suggested by rigs).
Have a good time!

Will this avoid the head collision? How?
No no, this was the wrong answer - respectively the wrong thread....
Just ignore me...

...
This was suggested in there and it looks like the next step that TinkerGnome has in mind (or maybe not the next but in the list)
Well..., not exactly this way...
The originally idea was to add some sort of "shift" value to the printing coordinates to make the recovering easier. But this would still need a reslicing...
The suggestion of Chris would be much more convenient, wouldn't it?
Let's decorate the dream a bit...
One could use the (still experimental) move axis menu to determine the correct z-coordinate and then just say "print the next file from here"...
...and the firmware would start a normal print but just ignores all moves until the specified z-height is reached...
...then initializes the stepper positions to the correct values... ...and starts printing the remaining part of the file... -_-
I guess that all these "dangerous" options will probably never find there way into the standard firmware - it's simply too far from "foolproof", but we are allowed to tinker with the idea of doing it ourselves... :roll:
It's a challenge - but maybe worth the efforts.... .... at least much more convenient than manual editing of gcode....
(i think i said this already....
)What did i miss?

Also fixed that the abort now almost instantly aborts instead of executing 16 more moves (think Tinkergnome managed to trigger me on how to do this)
...
Really? I swear - this was a simple misunderstanding... :huh:
(damn - i hate these annoying merging sessions every evening...)
-
...
The buffer need to be finished before getting the abort command
...
I think, this is the main issue - it should not be necessary to complete all the buffered commands - because we want to abort anyway...
David has commented this long ago:
...
I tried clearing the buffer, however, I ran into odd synchronization bugs. So I opted to leave the buffer alone on abort.
...
Perhaps the firmware runs into problems because the printer is not longer aware of its current position after a "quickstop" (which clears the buffer).
Someone ( :rolleyes:) should investigate this a bit further....
Another quote :cool: :

Are there any detailed guides on what the various settings/gaps should be on re assembly of the hot end?
...
First choice should be the Assembly manual.
The interesting part begins on page 55/56:
turn the hot-end isolater until the teflon isolator part creates a gap of at least 1 mm and the bottom of the hot-end isolater is just not touching the messing part -
The visible changes are small this weekend.
Instead i refactored a lot behind the scenes (although it was working well - dynamic memory allocation is not the best choice for such a project).
The "Move axis" menu has the new home icon from rigs - and it has a new home at all. I moved it down into the "Expert settings" - i think it is better to group such things together (at the moment).
The binary files on GitHub are refreshed (although there's no need for an immediate update).
Alongside i try to prepare one ore more pull requests for the master branch.
Let's just go step by step through the todo list...
I think the "Shift axis position during print" is the next task.
See you!
-
Ok ok, i agree - "tune" would be obsolete.
...
Of course tinkergnome,this is not a race ! You have alllllllllll the time, until the next idea...
...
Yeah... - that's already clear - there's no innovation without a bit of pressure....(i will need some holidays soon...
)...
I hope not to be too boring.
...
Is this a translation issue...?
(or do i confuse "ennuyeuse" with "insistante"...?)
:lol:
-
I see - you're probably never running out of ideas....
I would like to replace the "ABORT" function with "PAUSE" - and integrate the abort function in the pause menu. I often use at first the pause function and decide later, if i want to abort... what do you mean...?
And there is no need to hide the "TUNE" button, there is still room for a third button in the bottom line. So would the tune menu be still accessible for evereone who likes it...?
...
2# screen
Retraction option
For Acceleration and x/y jerk, I do not think this is possible ?
Led adjust.
So, you suggest a second level of "instant tuning" options...
Why not...? .... if you don't expect it for tomorrow... :roll:
There are gcodes for acceleration and jerk already - so it should also possible to change it manually during print.
I should better avoid to bring in new ideas.... but here are some examples...:
* M200 - Set filament diameter
* M201 - Set max acceleration in units/s^2 for print moves (M201 X1000 Y1000)
* M202 - Set max acceleration in units/s^2 for travel moves (M202 X1000 Y1000) Unused in Marlin!!
* M203 - Set maximum feedrate that your machine can sustain (M203 X200 Y200 Z300 E10000) in mm/sec
* M204 - Set default acceleration: S normal moves T filament only moves (M204 S3000 T7000) im mm/sec^2 also sets minimum segment time in ms (B20000) to prevent buffer underruns and M20 minimum feedrate
* M205 - advanced settings: minimum travel speed S=while printing T=travel only, B=minimum segment time X= maximum xy jerk, Z=maximum Z jerk, E=maximum E jerk
* M206 - set additional homeing offset
...
* M928 - Start SD logging (M928 filename.g) - ended by M29
* M999 - Restart after being stopped by errorYou will design some nice arrows, right...?
We should stay at 7 pixels in height and as wide as necessary for a smart look...?
Stay tuned...

Ahhh.... is the UM2s X-Y origin (0,0) the top left hand front part of the build plate?...
Short answer: yes

Hi,
sorry für die dumme Frage aber wo liegt der Vorteil gegenüber dieser Platte hier?
(evtl ergibt sich hier auch eine Ersparnis bei Abnahme von mehreren?)
Mir wären die 2mm mehr und die 4 Bohrungen keine 20€ mehr wert..oder übersehe ich etwas?
Mal sehen...
- es ist nicht angegeben, womit genau die Platte beschichtet ist (gut, das könnte man evtl. nachfragen)
- die 2mm mehr machen eine Menge aus - zu dünnes Alu verzieht sich leicht - und auch hier: keine Angaben (oder gar Garantien), wie eben die Platte ist
- die Gewindelöcher haben ja den Sinn, auf Klammern oder ähnliches verzichten zu können (aber Du kannst sie natürlich auch selbst anbringen)
Ob es seinen Preis wert ist, muss eh jeder selbst entscheiden...
(nur meine 2ct.)

Why is a house icon for the bed temp "intuitive"? I'd call it misleading.
As rigs said: this are two different topics. We want to use the house for the (recently added) "Move axis" menu.
And the bed temp icon is intended for the "Heatup screen" (== priming screen) - this weird thing that you probably rarely take notice of - because it's shown only for UltiGCode during the heatup stage.... :wink:
Till later!

I thought you had done a pull request but didn't.
...
Correct, there is no pull request for this topic yet.
I think this were too many little changes in a lot of files for a single pull request (at the moment).
I consider to make several step by step suggestions (via pull request) instead. This will take some time and effort, but is probably a better approach.
(and as a side effect: one can notice earlier wrong directions - and if the master it likes or not... :roll: )
We will see...

Do you know what is Daid's position regarding your dev?
...
There is no explicit pushing from my side - i'm too prejudiced...
David made a statement in this thread. That's not a categorically reject - i think.
...and the pm_dude seems to have more "insider" knowledge ... ?
...
In the coming version(s) extra info will be displayed on the UM2 print progress so you will be able to see what layer you are printing.
-
Cool, seven at one blow... B)
I think the little house is the most intuitive and deserves closer attention, would you agree?
...
You can replace the icon bed temperature in the priming screen by the adrien's icon ?
...
A trick question this is...isn't it...? :rolleyes:
(you are right - let's put it on the virtual todo list)
...
I have a question,it is possible to start printing with a specific Z ?
...
I hope so... - that would be the next logical step. :arrow: :arrow: :arrow: todo list...
Something like the X/Y/Z Shift plugin * - but not restricted to Cura.
* - This plugin is fairly old (that means... older than the Ultimkaer 2) - but with a small modification it could still do it's job - even for recent Cura versions.

...
I encountered a min temp once when I came in from the cold and wanted to start printing. After it was warmed up to like 10-15 degrees it worked fine again.
...
Well, there are minimal temperatures defined in the firmware - could this be related to this...? Seems to be another security feature...
From Configure.h:
// The minimal temperature defines the temperature below which the heater will not be enabled It is used
// to check that the wiring to the thermistor is not broken.
// Otherwise this would lead to the heater being powered on all the time.
#define HEATER_0_MINTEMP 5
#define HEATER_1_MINTEMP 5
#define HEATER_2_MINTEMP 5
#define BED_MINTEMP 5
If the printer works fine after it is "warmed up" this could be an explanation...

You are talking about the small 25mm fan behind the extruder? Then you should follow http://umforum.ultimaker.com/index.php?/topic/5442-feature-request-allow-to-turn-off-fan-behind-extruder/
There are some recommendations for a replacement.
Yeah... - that's already clear - there's no innovation without a bit of pressure....

Perhaps i missed this... but... have you beared in mind that not every fan is pwm-controllable..?
(i can not find this information on the product page...?)
