D3D Product Testing
Prusa i3 Build
Software
This is the 3D printer of the first iteration of OSE's workshop.
- Testing the Live ISO downlaod from D3D Live ISO - I downloaded from the Dropbox since the first link failed to do complete downloads - it would quit about half way.
- Creating live USB as in D3D Live ISO. Formatted to EXT4 using Gparted, and opened ISO in Archive Manager. Extracting does not work:
Suggestions
Wow, that USB stick had a long name. You change owner with chown. Try: sudo chown -R marcin /media/marcin/24667c8b-dd03-4286-b350-7d35edd72f63
The -R gives you ownership of the USB and everything inside it.
The group owner is changed with chgrp. Try: sudo chgrp -R marcin /media/marcin/24667c8b-dd03-4286-b350-7d35edd72f63
This will hopefully solve the write permissions problem once. To solve it permanently, it looks like you have to alter some file in /etc/udev/rules.d. See https://askubuntu.com/questions/17540/how-do-i-set-executable-permissions-on-a-removable-drive and https://stackoverflow.com/questions/1736942/auto-permissions-on-udevd-device-files
Alternatively, get around permissions-stuff by doing it all with sudo: sudo apt-get install p7zip-full sudo 7z x Porteus-D3D-Workshop-x86_64-v2.iso -o/media/marcin/24667c8b-dd03-4286-b350-7d35edd72f63
Hopes this extracts the iso for you. Very irritating bug in your operating system that gives the wrong permissions to USB drives...
Hardware
- First calibration cube worked well the first time around, with Folgertech_Kit#Build_Instructions. Power supply blew the second time it was turned on - the ground wire was connected to the neutral terminal on the power supply, and the neutral wire was connected to the ground terminal on the power supply. Note: this is interesting in that it worked the first time around - it shouldn't have.
