Why cant I write to the Z bed offset? It is set to zero after I flashed. Not a negative number as is has been before. So now it is not possible to set the true Z-axis? (this part: http://wiki.e3d-online.com/wiki/Printer_Commissioning#.284.3.29_Calibrating_Z_Offset) There is a Bed Z that is 0,000 and can go to -1.000 before it was like 2 digits in the end... and I think it was called Z offset... Hmm... this is not done with mesh leveling?
Somehow I bricked my BB where I couldn't flash it in avrdude. It just kept getting timeout errors. The solution was to reflash the bootloader. Generally a USBasp device is needed but if you have another Arduino around you can use that and load a program to act like one. I connected a spare Arduino Uno to the ISP pins on the Rumba and reflashed the bootloader then all was good. It just took me a few hours to figure out that's what I had to do. I used this guide as a good outline of what to do: https://www.nova-labs.org/wiki/3d_printer_build_group_7_instructions/flashing_rumba_bootloader
Hi all, I'm struggling a little with this initial setup. I'm not 100% sure what to do here: Copy the U8glib folder from Arduino_1.0.x\libraries\ and Arduino_1.6.x to the libraries folder in the location we installed Arduino IDE to. If you accepted the defaults and are running x64 Windows then it will be C:\Program Files (x86)\Arduino\libraries\. If you are running x86 Windows then it will be C:\Program Files\Arduino\libraries\. I've copied the U8glib folder no problem but what should I get from the 1.6.x folder? Should there be another U8glib folder or something else? I'm running Arduino 1.6.11 if that makes any difference. When I try to compile I get this: From the description, I'm not sure if it's worked or not?!?! Cheers Jason PS: I can upload using XLoader no problem, I'm just beginning to try through this route.
It's compiled. THey are warnings, not errors. You should have a .hex in the project folder. or it may have flashed it depending on the option chosen.
Built RC6 on OSX with Arduino-1.8.1 and found an easier way to flash than with a USB cable. Ok, easier if you're used to unix... 1) Verify (compile) the code 2) cd /private/var/folders 3) find ./ -name "Marlin.ino.hex" you'll see something like: .//03/0mt_n9lj4y56n6nld7dttyl00000gp/T/arduino_build_477962/Marlin.ino.hex (and a bunch of permissions errors) Copy that file back to your Marlin directory, then use octoprint to flash.
