Any chance of an update that allows manual heating of buildplate?

@neuronex, I was wondering if there were any updates. How is the leveling going now?
Yeah it's all good now thanks.
I realized the problem was with the Print Core as I'd previously come in to find the print head packed full of ABS after a night of printing and material got stuck and ended up jamming and melting up into the print core. Something must've got damaged on the print core causing it to malfunction and gave me the issue I reported. Replaced the print core and it's all working fine now.

Mine is printing right now so I cannot check, but ti should always go through a leveling process on its own just before printing. If that is not happening, then something is really amiss as you cannot turn it off.
It is set to run that automatic leveling to compensate for such a large glass plate heating up and deforming, if only a tiny, tiny bit.
Strange - because when I first got the printer there was a menu option for auto leveling and I had it set to 'never' as I usually run the active leveling manually myself every few days rather than before each print. After the firmware update the Active Levelling option is no longer available.

Replaced left side Core AA with another unused Core AA, Core BB in the right.
After running bed leveling selected XY calibration.
For the first time it ran an active leveling test before the calibration and it seems to be fine now - core BB printing properly.
Not sure if replacing AA forced a reset, or there was an issue with AA core. Will see once XY calibration is complete if menu option for Active Leveling is still missing.

If it is passing a leveling (The automatic one before each print), and then crashing a nozzle into the buildplate, then something is amiss. It could also destroy a nozzle like that. That is why I suggest getting in contact with reseller.
Yeah oddly after updating firmware the automatic leveling is no longer available. Not even in the menu.

I mean that when you manually level the bed it levels to Core AA (on the left) then right at the end you do a single level adjustment for BB (Core on the right).
-
Have inserted another AA core (so both slots are now AA - AA) and still the second print core (the one on the right) presses into the buildplate when printing. Have levelled the bed again with no luck.

Hi,
Issue: Print Core BB presses into the buildplate when printing.
I've installed Print Core BB for a second material.
Did manual bed-leveling - both cores leveled properly.
When starting a print - Core AA prints fine, then BB prints but presses right into the build-plate by almost 1mm. Have leveled the bed again, ran the XY calibration setup, but that doesn't work because once AA has printed it's grid, BB comes and presses into the bed again. Any idea what the issue might be? It's like there's an offset somewhere that's putting the BB Core closer to the buildplate, however - it can't be in Cura / slicer because I had the same issue after leveling and running the XY calibration setup.
I'll also note here that auto-leveling has completely disappeared from menu since the latest 5.0.19.20180622 update.
Thanks.

Can't seem to find the Print Sequence in CURA 2.3 with the UM3 selected. Am I missing something? Have two small models loaded as per previous UM2+ builds.
-
No option to set LED brightness during print? Why take that away?
UM2+ I'd start print with light on the check quality but switch off if running overnight.
Also, on the XY offset chart...
16 comes AFTER 15, not before it. How do you get 16 between 15 and 10? How have these things not been checked before printing?
And also this is confusing at first:
That printout actually makes no sense until you read the manual and see that the glass plate needs to be removed.
-
Just to add to the thread - I'm not at all happy with the quality of the machined front panels. The quality isn't great at all. It's this rough all the way around.

to download my personal S3D fff profile. (click on the 3 dots on the top right and select download to grab it)
Good luck!
Thanks
.Your prints came out with a nice solid top layer.
Going to try it as soon as the machine is finished it's current print.
(I see you've set your build volume / table size larger. Any reason for that?)
-
Sure...Can you post the stl of this, so we can try and see what results we get??If an improvement could then upload our profiles

Adjust the nozzle extrusion width to 0.35 like cura does. Sorry really busy week I can't check your fff yet
It's been at 0.35 all along. I'm trying another process now with it at 0.4 as well as increasing the outline overlap. Will see what happens.
-
Increased extrusion multiplier to 1.05 but still get a problematic top layer.
Also tried increasing # of top layers to 10.
-
So I've have had some nice prints from S3D, however I still get some top layer issues not being 100% solid, especially around the holes.
CURA print is almost solid:
S3D print has gaps around the holes:
Both printed with 100% infill.
Have tried slight adjustments to extrusion multiplier without any luck.

Auto' doesn't do anything auto, it could be nice if it where a real auto settting, but isnt.
Strange how on AUTO it seems to make the line width more than the nozzle size (about 1.2x), whereas CURA typically sets it just below the nozzle diameter:
CURA:
Will play around with it.

Thanks for the detailed reply - much appreciated.
Unfortunately the machine has been printing non-stop since we bought it & I haven't had the kind of time I'd like with a few calibration blocks trying different settings. I was admittedly in a bit of a rush to use S3D
.Will report back once I've had a chance to go through everything and run a few tests.

Hi,
[Machine: UM2+]
[MATERIAL: PLA]
So I switched over to Simplify3d (V. 3.1) in order to get more control over support structures, process settings etc. The biggest problem I'm having is the Top Layer quality is usually quite bad. I've tried:
Adding more/less Top Layers
Reducing print speed for the top layers
Some slight temperature adjustments
All my prints with S3D thus far have had an infill of 60-90% and always come out bad. CURA prints quality prints every time.
CURA PRINT:
S3D PRINT:
The S3D print hardly has the hole features which are clearly visible in the CURA print, S3D Top Layer print is also not as smooth as the CURA print - there's often visible layers. Anyone else had these problems?

If you have selected "print one at a time", Cura will show the low box to tell you what you can print "one at a time" (i.e this is what fits under the gantry height)
Ah - that's it.
Thanks.

Hi,
Since downloading CURA 2.1.3 it displays the incorrect height (the blue wireframe box) for the Ultimaker 2+. I don't have the UM2+ attached via USB so this is a software issue. The only workaround is to add a new UM2+ machine each time I start CURA which then gives me the correct height, but it defaults to the incorrect height the next time I use CURA.
This happens regardless of the part I'm printing.
Anyone else having the same issue?
Windows 7.
CURA defaults to incorrect height:
If I add a new machine & select UM2+ it temporarily shows the correct height:

S5 - Pause at layer height forgets where to stop
in UltiMaker 3D printers
Posted · Edited by neuronex
I've had two similar issues with the S5 using Cura's Pause At Height script.
For example I've set two pauses: one at 5mm height, the second at 10mm height.
Example 1:
S5 pauses at 5mm - all good. Then I resume but the next pause isn't at 10mm, it occurs at 7 or 8mm.
Example 2:
Before reaching the first pause at 5mm, core BB requires a filament change which pauses the print and prompts for new material. I change material in core BB and resume print. The subsequent pause at 5mm occurs instead at some random value like 3 or 4mm.
In neither case does there appear to be an absolute value that's adhered to. Machines are using latest firmware with latest Cura (I had the same issue in previous versions). Anyone else having this or found a fix?
Thanks,
