After a long time, I have finally found the time to update my old fuelstation finder for GPL/CNG fuled cars to a current Maps API and current design language.
The buggy OpenStreetMap code had to go. For the time being there is only the Google Map now.
The overlays are completely redone,
the layout of cause uses proper fragements,
the geolocation API usage and settings handling is updated as well.
Due to Google Code shutting down,
I scheduled the OpenStreetMap Vespucci Map editor project for Android to be migrated tonight (all commits done).
However the migration tool offered seems to consistently fail. :/
And I'm not alone.
Github has identified files >100Mb to be the most prominent cause but since my and other people's entire repository is considerably smaller, that isn't the case here.
He seems to be using the same printer I am (Ultimaker II) in the same way (very high precision parts at maximum reliability).
Not just "buy a printer and print trinkets I found from Youmagine or Thingiverse"
I'm using my Ultimaker II a lot and I'm taking good care of a clean nozzle.
Now I'm starting to get underextrusion issues.
I cleaned the bed of any glue stick residue
leveled the bed
cleaned the nozzle using cold pull until I could see through
Extruder tension was at minimum, I tightened it until the indicator was in the center
The issue is still there. Just with a bit more skipping then before
It started last week with an object that requries lots of retraction and happened after hours of printing.
Usually my objects need no or nearly no retraction. So I didn't think much about it.
How it happens in a perfectly cleaned and recalibrated printer within the first layer.
I fear my PTFE liner may be completely used up.
I did order 2 new ones but since they get delivered with FedEx, they may not reach me.
(No delivery after work hours and no possibility for me to pick them up.)
I'll loosen the extruder tension again and redo the cleaning.
Maybe I just over-tightened the extruder.
The underextrusion returned within minutes in the first layer.
I lowered the extruder tension and set my first layer to run at 50% speed until my replacement parts arrive.
This helped a lot.
3D printer (Ultimaker II) working on another 26h build...
That's a small one by my standards. While I'm away for the weekend it will do another 3 day job and I have even run extremely detailed 40 and 100h jobs without any hickup.
...at 20 Micron, that's 0.02mm compared to 0.1 or 0.2 or 0.25mm in other printers.
...out of the box with good quality filament.
I just love the reliability. Never seen anything like it with RepMan 3.0/3.2, ThingOMatic (on the contrary), Makibox. For exactly that teason I'll never, ever again buy a Makerbox Industries product.
(Apart from "Takerbot")
I hope Makerbot will get a lot of competition, now that Ultimaker has extended from Europe to North America.
You should regularly
check extruder tension. The indicator on the side should not be in the upmost position. Insert an allen key/hex key in the top and turn left (out) to make it tighter, right (in) to make it loose
check bed leveling
clean your nozzle with a cold pull (manually push filament through, then cool to 70-90°C and pull it out). Don't pull or push too hard as the PTFE liner is only held down by a spring and downward filament movement. It's als called the "atomic method" but it was known long before there was a U2 forum.
clean the bed of residue glue stick with a wet paper towel, reapply a very thin layer of new glue
Maximum spool size
Given that reliability, it's printing A LOT. 750g spools are extremely inconvenient.
These 2.2Kg spools from Colorfabb from are great.
I'd have loved 5Kg or 20Kg spools (both sizes I used before, stored next to older printers using garden hose holders)
but 2.2Kg is the maximum the Ultimaker II can hold.
Everything else would be wider and lower then the body of the printer itself.
The Near Future
I can't wait for the Ultimaker II Extended, that I already preordered!
The increased hight combined with the reliability of an U2 is exactly what I need for my parts.
Spare parts and shipping
The only downside is that
is demanding steep prices for the wear parts (PTFE liner, nozzle, hot end pack),
dubling the price with their enourmous shipping fees and seems to use
(Of cause if this is a minor issue and if it's the only thing I can complain about, that says a lot about the quality and reliability. I'm using this printer nearly constantly day and night.)
Express meaning it takes twice as long and may not
reach you at all if you just so happen to work during the day. Curiers
don't have post offices everywhere where you can pick up your packages
They often don't have storage locations in the same city
reachable without a car and they don't deliver or offer pickup on
So for me they are evil as I work Monday to Friday in different cities.
Express curier services are for and ONLY for deliveries to businesses that have offices open 9-5.
NOT for delivering to private citizen who work in these offices 9-5 and are thus not at home.
They are NOT replacements for postal services. They where never intended to be.
the new Ulti-Quality setting the first layer needs a lot of attention
and benefits from reduced speed and increased filament flow.
that it's great. I don't mind that that it takes ages as it reduces the
time I spend in sanding and other post processing after the machine has
finished it's job.
Since Resolve (and the free Resolve Lite) doesn't support one OpenFX method,
the Openfx-Misc set of free plugins needed an update.
After a discussion in the Blackmagic forum, this has now happened. I was able to compile them without any issues and they do show up in my Resolve 11 Lite on MacOS.
a side node: openfx_yadif (for deinterlacing) is still crashing in export after 5-20
frames. It does work in the color tab. Even with playback running.
I'm thinking about a wide color gamut display for Color Grading in Blackmagic design - Davincy Resolve.
It will also be used in Final Cut Pro X.
...and VLC. ;)
The HP Dreamcolor Z27x (720eur 2048 x 1556)
sems to be more affordable compoared to
the EIZO ColorEdge CG247-BK (1500eur 1.920 x 1.200)
or EIZO ColorEdge CG277-BK (2000eur 2.560 x 1.440).
You save 100-200eur for the calibration device but both need the Ultrastudio Mini Monitor as an added cost factor.
100% sRGB Coverage
100% Adobe RGB Coverage
100% BT. 709 Color Coverage
99% of DCI-P3 Coverage
I'm planning to use the
Blackmagic Ultrastudio Mini Monitor
to output 10bit 4:2:2 YUV
since the newer Z27x supports the DreamColor Engine with YUV and not only RGB now and the Mini Monitor is limited to YUV only.
problem I have is that the cheapest, supported calibration device (HP
DreamColor Calibration Solution(B1F63AA)) for the Z27x seems to be half
the price of the entire monitor (200eur). :/
A Spider4Pro or
Spider4Elite that cold also calibrate my other displays and laptops
would not work with the internal LUT of this display. :/
On the other hand the B1F63AA is much more accurate then the Spider will ever be.
720eur + 100eur + 150eur = 720eur
less quality control
no sun shade
4K downscaling, 1:1 4 corners + center + dynamic panning
