It was brought to my attention that there are still people trying to access my old TP, Xpresso presets and other example files.

Many of the files will not load correctly in current Cinema 4D versions since they are partly over ten years old and to much has changed since then.

Vacation on a beautiful island

Share on FacebookShare on Google+Tweet about this on Twitter

Our vacation in 2016 brought us to the Acores, more specifically to Terceira. Different to the largest island Sao Miguel Terceira has only very limited tourism. What we experienced is a lifely island with beautiful landscapes, coasts and buildings, as well as a lot of friendly people. Surprisingly many of whom spoke english, which easily made up for our total lack of portugese.

The Hotel

Terceira Mar Hotel was our first choice and it was a good choice. The room was clean, the view spectacular, the employees friendly and competent and the food good.

The huge salt water pool was a welcome refreshment after a day of touring.

Angra do Heroismo

Angra is the capital of the island and the largest city. The city center is in walking distance from the hotel, which made it easy to discover restaurants and shops before falling tired into our beds

The Coast

Since Terceira is a volcanic island there is little what you would call a sandy beach. There are a few smaller patches that are inviting for a swim though. The locals mostly make do with what is prepared for swimming by adding ramps, handrails or steps.

On the Island

I let the images speak for themselves, this is one of the places I really want to visit again.

Since agriculture is a primary part of the islands economy a lot of land is used for cattle and crop, however the efforts to conserve the islands beauty are paying off, you don’t see any massive scale fields or herds, on the contrary, what is there adds to the experience.

Volcanos

The main reason for the existence of the island is volcanism and it shows. Not only at the coast where the lava met the see, but also inland where most of the walls that seperate the fields are made of volcanic rocks.

The last erruptions happened only a few thousand years ago so there is still some activity left.

One of the volcanos can be visited and differently to most volcanos on the world you can visit this on the inside!

Misc

The highest point of the island is Serra de Santa Bárbara. On a clear day the view is phantastic and you can see some of the other islands of the acores

The Whale Dolphin watching tour was a failure success, we saw at least 20 dolphins.

Food

Last but certainly not least, the portugese like their food and here on Terceira that means either sweet, meat, cheese or fish. All are excellent and even the smallest food joint can cook up a mean burger. Don’t forget to try the icecream and don’t bother with Strawberry or Vanilla, go full hog 🙂

Books, books and more books

Regale01 Regale02

I have decided to get rid of a good portion of my printed books. An estimated 3000 books are up for graps, mostly german Science Fiction and Fantasy. I am still sorting out many english books where i haven’t decided yet what to keep and what not.

I just want to give them to a good home so they are not up for sale but i will simply give them away to anyone who is interested in reading them 🙂

If you are interested mail me at  books@bonkers.de

All books have to be collected here in Friedrichsdorf.

New GreenTec Filament from Extrudr

On the left printed @0.15mm Layer height with an 0.5mm nozzle on my DuoCore @210°C. On the right printed @0.2mm Layer height with an unknown nozzle @200°C on a friends i3. What is interesting are the differences in slicing, the left was sliced using S3D, the right one with Slic3r.

I was very positively surprised by the new GreenTec filament from Extrudr, that i ordered on a whim alongside a couple of kilos of my usual ABS.

Not only does it produce a nice matte finish, it prints without any hint of warp, the stability is excellent and it is a dream to postprocess with any kind of tool.

The only two drawbacks i found so far are that it sticks so strongly to the printplate (aluminum with 3Dlac @60°C) that damage to the part or printplate are a very real threat and the current price of €56 / Kg

I hope the price goes down over time, but even at the premium it might be worth it, especially considered that i don’t have to feel so bad about producing garbage prints since GreenTec decomposes neatly, different to PLA.

Thermal Runaway – Silicone cover to the rescue

Silicone Cover after Thermal Runaway

Silicone Cover after Thermal Runaway

As it turned out, it was a lot earlier than expected that the silicone sleaves from this posting

Silicone Sleave for Merlin made the trouble worthwhile. Some peculiar behavior of Marlin lead to a thermal runaway for a couple of seconds at full power. The silicone, that is rated for 450°C deteriorated, but the extruder remains unharmed and even the hotend survived thanks to the new cooling.

For those interested, what happened was that while homing Z Marlin stopped working completely. Everything was frozen including menu and the PID for the hotend, which got stuck with the heater switched on. I haven’t found the reason for the behavior yet, but i’ll do the homing before the heating in the foreseeable future.

Interesting differences in print quality

CloneProblem02 CloneProblem01

These two extruder bodies were printed in clone mode. The white one shows serious stribes that resemble Z wobble, but the blue one doesn’t. Since only X movement was different between the two it is either that, which i don’t believe due to the error existing on all sides, or it derives from the difference in the material. Interestingly the original setting was for the white material. If anything the blue one should show small signs of underextrusion since the filament diameter for that was smaller than for the white.

 

Edit:

This is the difference in stepping distance when doing 0.1mm steps. This is not simple z wobble but something different again since it occurs along the z axis, not perpendicular to it.

Interestingly the problem is uneven movement along z, not perpendicular to it.

Slot Cooler 03 Slot Cooler 02 Slot Cooler 01

On the RepRap forum the question came up how the Merlinb hotend is cooled when printing Polycarbonate @ 260°C
The design i currently use is rather simple, it focuses on cooling the lower part of the PEEK and guides the airflow as far around to the backside of the hotend as possible. Ultimately i would like to be able to press all air through a small gap at the lower end of the PEEK, but that is a tight fit given that the heater block needs to be insulated.

A few Hotends

Hotends

Here are a few hotends i have lying around,. While i obviously use the Merlin most, i also employ the Hexagon sometimes.

I haven’t come around to actually using the E3D yet, though i did some extruder designs for it. The Prusa hotend will very likely remain unused till the end of time 🙂
