Was kann/muss ich tun, damit ALLE Cura Einstellungen greifen?
Für alle älteren Cura-Versionen bis (einschließlich) 15.04 kannst Du in den Maschinen-Settings einfach den GCode-Flavor auf "RepRap (Marlin/Sprinter)" umstellen.
Die neue Cura-Version 15.06.xx ist in dieser Hinsicht (noch?) etwas verkrüppelt - genaugenommen nicht nur in dieser Hinsicht... :angry:
Damit hast Du nur die Möglichkeit, als Druckerprofil den "Ultimaker Original+" auszuwählen,
oder im Installations-Verzeichnis die Datei ".../resources/settings/ultimaker2.json" von Hand zu ändern. Relevant sind (mindestens) die Einstellungen "machine_gcode_flavor", "machine_start_gcode" und "machine_end_gcode" - aber das wäre dann schon sehr "experimentell"...
Am Ultimaker2 bekommst Du in beiden Fällen nach Auswahl der Druckdatei die "Classic Warning" - und das bedeutet, das die Material-Einstellungen vom Drucker nicht benutzt werden. Also genau das, was Du erreichen willst.
-
Then the question is - why Ultimaker does not support STEP? We send our files to machine shops here in the US, and to China - all CNC shops understand that format.
It seems to me that supporting STEP files is on the wishlist for a long time. Perhaps it's worth to reopen this old discussion about Stepfiles and G02/G03 arc gcodes?

in order to disabled sensor_2 but apparently, it's not the right way...I'm not sure sensor_2 is the sensor of the second head !
As you mentioned - it isn't... TEMP_SENSOR_2 is not relevant (not used at all for the UM2 AFAIK). The counting begins at 0 (TEMP_SENSOR_0 for the first etc.)
Only two different defines are needed to compile the stock firmware either for one or for two extruders. And this should work similarly for the tinker version:
Single Extruder:
TEMP_SENSOR_1=0EXTRUDERS=1
Dual Extruder:
TEMP_SENSOR_1=20EXTRUDERS=2
I've just added the (compiled) dual version to the recent tinker release.
I'm afraid that you will have to make some other changes - but this depends on the type of your hardware modifications.
Just be aware that you probably have to struggle with the compilation anyway (sooner or later)...

On the UM2 card, I can see 3 connectors:
Temp3 with heater of head 1
Temp2 : free
Temps1 with PT100 of head1
How do you control the second head?
This is only almost correct...
Temp3 should be connected to the temperature sensor of the heated bed.
Temp2 is intended for the PT100 sensor of a second nozzle.
The nozzle heater is connected to the screw connector marked with "heater1" - "heater2" is apparently intended for the second heater (consider the provided voltage (24V AFAIK).
If you're in doubt - take a look at the board description or at the assembly manual

Why did you go with a 60 y/o one?
@SandervG: don't you know the latest photos showing the 3dsolex workshop? Can you imagine a machine that outperforms the precision of this one:

Looks like it's printed without support... which slicer (and which printer) do you use?
BTW: could you add your printer (and location) in your user profile please?
An advice is: print it with support...
If you model this piece by yourself, you can even make your own support structure. A narrow frame below the edges of the cuts (to support the perimeters) is sufficient. Leave a gap of about 0.15mm at the top of the support structure.
The rest of the surface can be bridged then very nicely.
Do you know the designing guide of the famous |Robert|?

i mixed in the quote from the other thread:
I am trying to set up my ultimaker 2 with the dual extruders. I can put anything together but I am not a programmer by any means. any advice?
...
Who can point me in the correct direction of the firmware i need.
Sorry, but it highly depends on what you put together...
(i think you don't explained this yet?)
There is a dual extruder version of the UM2 firmware from stock - included in all recent versions of Cura.
You know your hardware setup - you have to decide if it is sufficient for you.
Edit:
Perhaps you could also explain how this topic is related to Simplify3D? Any firmware runs on its own, there should be no dependency on a specific slicer....?
-
So which way gives you the bumps? checked or unchecked?
Well, "unchecked" is the default for all recent Cura versions since 2015 (15.01 and newer), "checked" was the default for all older versions.
But it exists as an (switchable) option only in 15.04 (AFAIK).
As a reference:
The differences were first discussed in this thread.

Hi @Kermit65,
if i were you..., i would... (in ascending order)
- add a small chamfer to the edges where the small parts are attached to the base
- printing with zero infill but a larger shell width instead (try 1.2mm - 3 shells)
- increase the layer height to (at least) 0.1 and increase the bottom/top thickness to (at least) 1.0mm - i even think there will be no drawbacks if you use a combination of 0.12 / 1.2
- consider to split the parts in a different way (to make it printable without support)
Edit:
...and don't use the default speed settings - the default infill speed (80 mm/s) is way too fast IMHO. Set all speeds to the same value (or the advanced speed settings all to zero) - and choose 40mm/s as the basic print speed.
- add a small chamfer to the edges where the small parts are attached to the base
-
while you're at it... The suspicious behavior is switchable in Cura 15.04 - so you can make a direct comparison if you like...

You can take a look at the assembly manual (page 65) - but as gr5 said: be aware that the recent changes (from 2015) are probably not included yet.
The side 2 fans take 24V in series so they get 12V each. To turn them to 100% is tricky:
@gr5: you really should accept that there is a menu option for this since firmware V14.10
"Maintenance -> Advanced -> Set fan speed"

Something else, there is an lowest temp limmit build in the printer to prevent it from printing with a cold nozzle, not sure whats the default lowest temp (probably much lower than 150) , but as the UM2 is open source any setting can be changed easily.
To prevent cold extrusions the minimum extrusion temperature is 170°C by default. That's a common Marlin feature and not special to Ultimaker.
The default of 170°C is set after power on and after leaving the "Move material" menu, but can be changed by executing a M302 gcode command.
In case of an Ultimaker2 one could even prepare an autostart gcode-file on the sdcard with this command.
As a conclusion: no need to fiddle with the firmware, just do it - we're curious!

Cheers I had a look at that, but i'm using cura and just for now want to manually add the code with retraction, that the bit i'm super struggers with.
Wait a minute... if i get you right, this is just a test for your tool changer.
You want to achieve a tool change on every layer (independent of any toolchange command).
And you're looking for an easy way to integrate a retraction (without the need to struggle with the current E-position), right?
My suggestions are:
- you definitly don't want to zero the e-position between layers... - remove the "G92 E0" lines - that's the main source of your problem
- if possible - remove the "G1 E..." commands too and use firmware retractions instead "G10" resp. "G11"
- or switch on (temporary) relative positioning ("G91 G1 E-2.5 G90" resp. "G91 G1 E2.5 G90")
This should do the trick.

This is still a VERY requested feature from us at Stockholm Makerspace
Hi Erik,
there is hope...
You could make a test with the latest version of the tinker firmware and/or discuss and endorse this pull request.
Greetings to Stockholm from the tinker cave...

@tinkergnome: I guess I have to change the 282, right ?
i think so... usually the order of the array elements is X, Y, Z, E
-
does anyone have the same problem?
Yep. Welcome to the club...
The issue is reported on Github, you can join the discussion, if you like.
-
Where can I find this setting ? In the Configuration.h ? What is it called ?
Yep.. :
#define DEFAULT_AXIS_STEPS_PER_UNIT
... but usually you don't need this.
One can set the steps per mm for each axis with gcode command M92 (and store the settings with M500 to EEPROM)
This applies to the UMO and to the UM2 as well.
-
Could you also post this on github? Makes it easier to keep of track of things. I don't see anything in the log file that would explain the crash.
-
Calum Douglas made this for the UMO
Perhaps you can seize his suggestion....?
Or, you could place one printer on top of the other. I'm sure Ultimaker would give you the laser cutting files for the spacer they have if you ask nicely. It's basically a small open box that you place on top of one machine so that another one can stand on top of it without crushing the bowden. Not sure if that would become too high to work with in your setup though.
@IRobertI - i can not believe that you missed the "The Ultimaker Spacer" resp. "The Ultimaker Table" (Adobe Inventor and dxf files included).... until now...
Should be easy to adapt for the Ultimaker2 - if needed?
-
Is it a bug or is there a better way of aborting a print and starting a new one?
Probably you are running into this similar bug now?
As a workaround you can prime the nozzle manually with the "Move material" function (as needed).

Is there a logfile on windows too?
If you Run as Admin there is.
Ok, i tried it with "Run as Administrator" - same behavior. And now?
You may agree that such a start is not very promising...
It's a german Windows 7 and the very first dialog leads to this:

Unfortunately, 15.06.1 doesn't work for me on Windows 7.
The first dialog appears, i select Ultimaker 2 - click on 'Next' and Cura crashes after a few seconds... :(
Is it a known problem? Is there a logfile on windows too?
I'm afraid the whole thing is just another public beta test at the moment...
and only good for scaring new customers... :(
-
Ah! This must be it then!
@gr5 - you are very beady-eyed...
I think it's worth to put this under a microscope...

or add an M302 gcode command somewhere to allow cold extrusions
