[Ultimaker Mark2 - The Smart Dual-Extrusion Upgrade]

 

I had sort of the same issue, it was with the first github versions. And with a to big difference between the 2 nozzles in the Z axe.

 

Similar to mine after I held the 2nd head out off the way until it was needed to measure distances.

Have entered my calibration readings in a previous post which should be a good start

 

Maybe you can try to change to the second head and then set the extruder offset.

About S3D, I've tried with it but I had some problems with infill and top layers so I stopped the prints, nice result but it take some time to heat up, and the tool change retraction is not always clean.

I post here my wip fff profile for the mark2

Noob question about Cura..

Someone could explain me how can I select a custom profiles for mark 2? I changed some settings from a protected profile, I saved it as a custom but I can not activate it

[Ultimaker Mark2 - The Smart Dual-Extrusion Upgrade]

HELP!!!

I have built The Smart Dual-Extrusion Upgrade and have run into a problem trying to run the gcode calibration set up.

When the heads go to the central prime position it causes my heads to crash against the front of the UM which then makes the print fail, and pick up/replace the second head fail as well.

I took the second head off when it did its prime (just the main head used) and measured the distance from the head to the front of the UM cabinet as 2.7mm, whereas the size of the 2nd head when attached is 3.0mm (ish).

Is there anyway I can alter the gcode to stop this happening - and of course change any Cura settings to stop this happening for later prints??

Any assistance much appreciated.

Andy

Check two things:

Make sure you got the latest version of the Cura definition files? There was an error with the initial start / prime positions in the first github version.

Second, in the firmware check Dual extrusion - > wiping position and set the y value to something like 40 mm.

I'm not sure that is the same problem but if it is, it also happened to me, I solved by setting the extruder offset to X {+18} Y {-22} before run the calibration gcode.

It worked for me.

Edit_

No, I was wrong, that movement is a G28 at finished print.

The printer is running the last gcode and everything goes alright

[Ultimaker Mark2 - The Smart Dual-Extrusion Upgrade]

Did you try

With either

In Cura check: Travel->layer start x/y and set it to something like 100.0/50.0

or

Then you could activate the Mart2Tweaks Plugin

or both

you should be fine (up to my experience)

Yes, I have set the layer start and I activated the plug in

I don't know how but now I repeated the slice with the same settings and the travel movements are reduced, there is only one, I think it is start movement after a G28

Hi to all,

Yesterday I installed all the different parts of the mark 2.

I have to congratulate you for the great work you have done.

After setting the various parameters, now I would like to make some tests to verify the extruder offset, but i noticed these movement to the front-left corner

Are these movement an error or are they generated from the swap script?

[Ultimaker Mark2 - The Smart Dual-Extrusion Upgrade]

...but when i print, as soon as the print starts, it goes to 250mm/s and 6 or 7mm. Is there some preset or setting i miss?

Many thanks!!

 

The gcode sliced from cura contains a lot of acceleration/jerk command to get better quality.

If you read the gcode you will find a lot of M204/M205 commands.

[Ultimaker Mark2 - The Smart Dual-Extrusion Upgrade]

First of all, you've done impressive work.

I've a question about gcode/firmware.

Are the tool change movement script, swap retraction managed by the firmware or by the gcode?

I read a dual print gcode generated in cura and i see T0/T1, M104/M109 command for the standby-heat up temperature, and a simple retraction (5.1mm@F1500) in relative E distance.

I ask you this because I don't have a lot of familiarity with cura and I would like to ask if it is possible to run a simplify3D's gcode, i know there is a possible collision with the 2nd head if the object is in the wrong position.

I also noticed that PVA is not present in the list of materials, but this is not a real problem.

Thanks,

/Marco

Ciao Manu,

Dato che nessuno ti ha ancora postato il suo profilo ti allego il mio.

Nota peró che non é ancora definitivo, ma ancora piú importante é che é scritto per la versione da me modificata di una UM2 con doppio estrusore.

[Problema stampa ultimaker 2+]

Ciao, premetto che non ho mai stampato in nylon e non conosco il materiale.

Tuttavia da come hai descritto il problema, suppongo che la deformazione sia causata dal raffreddamento, mano a mano che il materiale stampato si raffredda si ritrae e si deforma. inoltre essendo cavo non c'é nulla che lo mantenga ortogonale.

Ho avuto un problema simile stampando in PLA/PHA.

i layer sono ben allineati sull'orizzontale o seguono la deformazione eccentuandola?

[Ulticreatr 2X: Dual extrusion for Ultimaker 2 and Ultimaker 2+]

I have some info and details.

 

How do you level the nozzle to each other?

 

The nozzles are leveled with steel's insulator which is screwed or unscrewed.

[Esperienza acquisto Creatr]

Ho acquistato una UM2 Ext ad ottobre circa, e anche io confermo l'eccellente servizio offerto da Sam di CREATR.

Sempre disponibili per assistenza e chiarimenti tecnici, anche quando si sono rotte delle componenti mi hanno fornito un'ottimo ed immediato servizio per i pezzi di ricambio.
