[UM3 fw update without lan (with usb)]

First i tried withouth extracting, then i tried with extracted files.

My usb stich is used to print all my Gcode files. I tried with all situations, formated disk, only the 2 files on it, booting with and withouth usb stick.

... Fw version i will look into tomorrow (i thought something like 3.6....)

 

 

[UM3 fw update without lan (with usb)]

Strange, doesn't work, the 2 files copied on the root of my USB stick, are not found bij the printer. Not in stable or testing version. Also tried to unzip them, but same problem.

Thanks, will try this out next monday ;-)

Same over here, Fusion 360 user, when i use the normal xyz planes in Fusion, the 3d generated files are always 90% rotated.

[UM3 fw update without lan (with usb)]

Hello,

What is the procedure to upgrade the FW on my UM3? I don't use wireless, so it must be done with USB.

Can't find the solution.

Many thanks,

Rudy

I also had this issue again some weeks ago, after it was gone for a couple of months.  I analysed my G-code, everything was perfectly straight! Did the print several times,  slanted!

Next time i encounter this, i think i will try to calibrate the offset thrue the slices settings.

 

 

[Cura Performance on Mac]

Strange, i use a old (ancient mid 2012) macbook air, I5 1.8Ghz with 4Gb ram, and the speed is acceptable. 

Can we do some kind of benchmark? Slicing same object with same settings and time this?

I've tested both versions of Cura now. 3.2 Release and 3.2 Beta and it looks different in the Release Version but it works as intended in the Beta Version. I'm gonna use the Beta for now, because the profiles work and the start script.

Same over here !!

 

[Printing with Polysmooth?]

On my UM3 and UM2+ mk2 dual extrusion,  i print at 220 degrees, my support material is polysupport, at 230 degrees.

Ok, but I use the Mark2 printer definition together with the printing profiles in Cura without problems. I was not sure, if we are speaking about the same things, that's why i ask....
Can you shine some light on what precisely does not work?

(perhaps better in a new thread)

 

@RudydG

Edit: I think, i know now what i made different, the root cause seems to be the link to the quality profiles of the UM2+. I made a new version for Cura 3.2.

Can you try the following printer definition with Cura 3.2 BETA?

 

Mark2_for_Ultimaker2.def.json

 

(right click and "Save target as...")

Wonderfull

Just tested it, it works!!!

3.2 beta with mk2, now i can choose profiles and materials.

This gives so much more "ease of work"

 

Many thanks, and hope support will continue as the next Cura versions are on the way ;-)

Try changing X and Y start at 40,40, helped in my case (um2 mk2)

What's the problem with the profiles? Are you talking about the printing profiles (Fine, draft, Coarse...) and why can't you use them?

Creating (and update) of custom profiles works fine for me too in Cura 3.1 and 3.2 BETA.

Or did i missed something different?

 

Sorry, i was't clear! It is the combination of the MK2 with Cura wich does not work with profiles. With my UM2 and UM3 no problems.

 

[Cura variable layer heigth]

Just changed to beta 3.2.

Will test this. But to be honest, the mark2 hardware upgrade is wonderfull!! Works like a charm!

But on the (cura) software side, it just sucks in my opinion. The fact that you can't use profiles in Cura, like with my UM2, and UM3, just makes it so difficult to change something (and remember all these settings)

Isn't it possible to use the um3 profile so we can keep all the advantages of the Cura software? The only diffence i see between the mk2 and the 3 is the way it changes heads / nozzles?

I run 3.1 with the Mark2 without problems. Maybe you should cleanout the Cura folder and do a clean reinstall? maybe you've had the Cura beta installed before and thats causing an issue.

If you decide to "clean out the cura folder" make sure you delete everything in %appdata%/cura/3.1/

 

Guys, i swiped my complete harddrive, every ultimaker or cura related thing, hidden or not hidden, was deleted. (the first crashing version of cura 3.1 never even made it to my computer)

Really sad, as Cura is the easy way to use an ultimaker (my UM3 at my office is 100% supported by Cura, wonderfull), but with my UM2+ MK2 i am really struggling.

 

[UM3 Dual Extrusion with 2 Different Size Nozzles]

I use the 0.8 pla laft + 0.4 polysupport right, works fine, just remember that layer height range is limited.

[Ultimaker Mark2 - The Smart Dual-Extrusion Upgrade]

I am still struggling with Cura 3.1, crashes all the time when loading someting, so went back to 3.04.

But there is still the problem with the quality definitions / can not save one, or load one. I know there is the solution in saving the project, but i have a feeling the 3.1 problem is related.

Does anyone has a solution? is it possible to get an updated "cura resourses" on Github?

Many thanks!

Hi Rudy, I managed to borrow a Polysher from 3DFilaPrint to do some more realistic models from the one that were used in the advitising to do a field test report on, I have attached the link to the file on their web site

For the Braq dragons we printed we found that they had to be left for a week to air dry and harden before being assembled otherwise they would stick together. Fine detail would be lost during the treatment and depending on the surface finish etc we could be using a 50 minute cycle time for some parts. Thin wall parts including the vase could collapse and if a filagree type print was too fine it would basically desolve away.

 

Thanks, will read this article, and see if i can get some benefits out of it.

Anyone using one of these?

I bought one, but until now the results are not what i expected.

Printing with the polysmooth is easy, but once polyshed, the results are not so good.

My parts are either not polyshed enough, or stay tacky even after several days. bottom of the polished part are also to "wet"

I tried several settings, but until now nothing satisfying.

My isopropanol is 99%

Any tips?

I have been playing with one too, what kind of settings are you applying?

 

I found that polishing for 30 35 minutes gave good results, im printing with .15 layers and it needs at least two walls and infill not to deform 

 

I tried a spiralize print but after polyshing it got very soft

Hey,

For printing i use .15mm, 3 shells, 225 degrees. Prints superb.

For Polyshing, i used several timings, between 10 minutes and 30 minutes. Tried to polish in 1 or 2 passes, in several positions.

What kind of isopropanol do you use?

Marco,

 

No problem, i will try your latest FFF files, and see what comes out of it.

Greetings and merry Christmas! (frohliche weinachten?)

Here is the complete FFF

Hello Marco,

I have the UM2+ dual head (magnetic toolchanger)

A lot of problems with Cura (which seems to be the thing to use with my UM3, but the support for a custom machine is problematic)

I see these FFF files. This is the way to go now with S3D?

Many thanks,

Rudy

I think, it's not related to Cura 3.1, you can (re-)enable it in the machine definition file, if you want ("Mark2_for_Ultimaker2.def.json").

Near the end of the file:

        "layer_start_x":
        {
            "default_value": 105.0,
            "enabled": false
        },
        "layer_start_y":
        {
            "default_value": 27.0,
            "enabled": false
        },

 

Thanks, a lot of settings i missed are in there ;-)

I have problems with cura 3.1, several settings are hidden, like travel > x start layer and y start layer, someone noticed this? ( the are hidden by the current machine??)

I always set them to 40,40 the avoid the unwanted moves and crashes from the heads.

 

Nobody? Anyone on 3.1 on a mac?

Thnx for your fast replay, I will check the forum how this works hopefully I get it fixed ;-)

Beside the problem with the power supply, i encountered 2 other issues that caused crashes.

1: when using the old printhead from the um2 (not+), the gap between the 2 nozzles is to big (Z offset), and you have to print a spacer.

2: put some x and y start figures (mine are at 40), to avoid unwanted head moves, outside the printarea, with fysical crashes as result.
