Auto Bed Leveling

First, Marlin is not working with auto bed leveling - axes are reversed. To change this, line 320-3 in configuration.h:

1. define INVERT_X_DIR true // for Mendel set to false, for Orca set to true
2. define INVERT_Y_DIR true // for Mendel set to true, for Orca set to false
3. define INVERT_Z_DIR true // for Mendel set to false, for Orca set to true
4. define INVERT_E0_DIR true // for direct drive extruder v9 set to true, for geared extruder set to false

Software

This is the 3D printer of the first iteration of OSE's workshop.

1. 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.
2. 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.
