It has been done for the UM2, but I don't know how complex it would be to get it on UM3 as the "Brain" moved from the "main board" to the "linux board". But basically in the simplest form a filament Y/N would be enough to detect material from running out, and triggering a pause function. A material movement sensor would be nice to pause when filament stops due to grinding, but to be honest I can't recall the last time that happened to me., I find the new feeders very reliable... https://ultimaker.com/en/community/7436-more-information-during-print?page=10&sort=#reply-120082

this can be helpfull for manual swapping; https://www.youmagine.com/designs/wedgebot-for-ultimaker2

If you run out the machine will not notice and just continue printing air. If you notice yourself you can indeed pause and change the material. In theory the machine should be able to track the amount left on a spool when you use the tagged Ultimaker spools in combination with the material use data from CURA, but this would only work if you only use the material on an UM3, and stuff like failed prints might make it less reliable. I really don't know if this functionality is currently somewhere on Ultimakers to-do list, but it should be possible. Like @daid mentioned, see the UM3 like a Tesla, gradually more functionality will become available with software upgrades....

I just use a bit of diluted glue stick works fine for me...

pretty sure this is the "horizontal expansion" which is a good thing if it's helping the PVA to build from the bed iso the PLA part. If the structure is to small you can play with increasing the horizontal expansion.

I don't see in the picture where it wen't wrong...... In my experience the PVA sticks very well to the bed, but a lot less to PLA. This can lead to problems on the wipe tower and on other areas where the PVA has to start on top of PLA. In the last case increasing "support horizontal expansion" in Cura can sometimes solve this, as it may result in PVA starting partly on PVA

Ultimaker manual adviced to take out the glass and put it on top of the calibration card, in this case a cool down is needed. I just look at the calibrated print in the machine and have the card at hand to read of the numbers, it's pretty simple, but taking the glass out is probably more "monkey proof" Anyhow not a very important discussion as you hardly ever calibrate xy so I got the machine before the manual was there what i was expecting, and what I was thinking of, is to have a hole in the calibration sheet, so you can just lay the sheet over the glass plate. you don't have to take the glass plate out then.. you can just overlay it.. I actually already suggested that in the beta phase... hope someone will pick this idea up...

@leoddc man thats really grose..... but fantastic !!

If not you can always do it hardware wise, just switching 2 wires on the stepper i believe.....

It really is not. It's super simple and you hardly ever have to do it....

you have to do stuff, here's the manual; https://ultimaker.com/en/resources/23125-print-cores

well..... almost. the calibration is 'remembered' per set of core's in the correct order. if you use a set of core's that's already calibrated, but switch there position in the head (left/right) you need to re calibrate. So if you don't want to bother to keep a set in the same order you have to calibrate each set 2x (which is peanuts on the lifetime of a core.....)

No, I have no plans for that...

You guessed right, XY is using bushings because they need to rotate. For maintenance have a look here; https://fbrc8.zendesk.com/hc/en-us/articles/207988073-Greasing-and-Oiling-Your-Ultimaker

Just ordered the connector at Amazon.de, as farnell doesn't seem to ship to the Netherlands. >>manufacturer link; http://www.avx.com/products/connectors/specialty/standard-2-5mm-pitch-battery-9155-000/ >>3D file; select the 5 connector type, and the 2.3mm contact height http://www.avx.com/download/interconnect/avx-interconnect-models.php?link=http://www.3dcontentcentral.com/3DCONTENTCENTRAL/PremiumSSS-Download-Model.aspx?catalogId=10084%26name=00-9155-000

I'll try to keep as much of the build size as possible, for now it looks like I might loose a bit in X and gain a bit in Z. My main intent is to be able to get the CORE quality in terms of usable temperature range to the UM2, but the easy swapping is ofc also nice. Be aware it comes with a cost, pricewise nothing beats changing a nozzle on an olsonblock.

Checked the data sheet. It's the correct size. Thanks !!!

That should be perfectly possible I think

Can you try to explain a little bit more? I don't really understand what your problem is.

I think these are about 15.- each at your ultimaker reseller.

I love the new CORE, so I'm planning to make a head to use it also on Ultimaker2 I have a few questions I'm hoping somebody can help out with. And just in general, If you have any idea's on the best head design just let me know; 1st, To electrically connect the core I need the connector with the metal pins, @daid is calling them pogo pins, but the ones used on UM3 don't seem to be pogo pins. If anyone can give a hint towards a compatible supplier and part? ( I'm using compatible as I assume UM employees are not allowed to disclose the used suppliers ) 2th A close look at the board by @Gr5 seems to disclose the left two pads on the CORE board connect directly to the heater, the right to pads go to the temp sensor (PT100), the 2th pad from the right seems to be shared 'ground' to the chip on the core board. I'm still wondering if it's safe to use the heater and pt100 directly, and I won't damage the chip on the CORE? anybody any idea about this? * , thanks for the pics of the board

There are a few more settings than brim/skirt influencing the total available build size. Read more details here; https://ultimaker.com/en/community/23300-cura-23-not-using-full-print-area

I had no previous vpn experience but did setup a vpn on my home router (fritzbox) in a few minutes just following the manual and the um3 direct camera stream (and beta app) work with it without any issue.... very pleased with it !! I'm using it from my android phone.
