No more abs-juice or kapton – printing on glass + hairspray
As the quality or brand of the kapton tape we have too many rolls of is not too good and whilst the print does stick well on kapton+abs-juice the kapton does not stay on...

Paristokäyttöinen WiFi lämpötilasensori testissä – Testing WiFi temperaturesensor with batteries
Update: 2015-04-20. Batteries lasted for about 11 days before the voltage was presumed to be to low as there were gaps in data (around 2.6V). Now it is hooked to a tiny solar panel...
Kokeiltua: 3D-tulosteen pintakäsittely asetonihöyryllä
Parista ohjepostauksesta ja Youtube-videosta inspiroiduin testaamaan ABS-muovista 3D-tulostetun kappaleen pintakäsittelyä laittamalla ne samaan tilaan höyrystetyn asetonihöyryn kanssa. ABS-muovi liukenee asetoniin ja höyrystettynä muovikappale imee sitä tasoittaen pinnan.
Printer up and running and calibrated
The service was pretty easy to finalize and z-calibration is not that far off. At the moment it is fixed in the 3d-printing workstation slic3r with “z-offset: -0.08 mm”. The former was -0.17. Might...
Mendel90 design improvements (aka fixing broken parts)
For some time the quality of prints has been varying. Occasionally pretty nice prints and on other takes something straight to trash. One time upon inspecting the matter I realized the x belt is...
