For some reason Makibox moved the head all the way out, I had to kill the power manually. However, the real problem was when I tried homing all axis: it started homing X first hitting the screw on the further end with the hot-end. Luckily the damage was minimal or non-visible, seems to be functioning fine after recalibration.

Homing Y first would eliminate this issue.

In Linux (tested on Ubuntu 12.04) when the printer is plugged in and powered up 5DPrint fails to connect to the serial port /dev/ttyACM0. This is due to a permission issue if the user is not logged in as root.
The permissions for the port are:
crw-rw---- 1 root dialout 166, 0 Nov 14 2013 /dev/ttyACM0
It would be useful if the application reported that the port was there but could not connect.
The fix was to add the user to the 'dialout' group.

Update

Can confirm that this is an issue in Ubuntu (12.04), Debian (Wheezy) and Fedora (20 beta). Users will need to be added to the dialout group if they are to use a Makibox. The Fedora 3D printing feature also mentions this.

In Linux to add a user to the dialout group run the following as root usermod -a -G dialout <username>

Subsequent instructions are sent, before M109/M190 are completed, although they should wait.

While manually changing the temperature via 5Dprint interface during and ongoing print job the print has stopped and the 5Dprint application has froze.

While pressing the respective Extruder [+] button on the interface sometimes, instead of just feeding one discrete quantity of filament the extruder motor instead starts to feed continuously non-stop. The same can happen with retractions using the [-] interface button, and in this case the result is continuous retraction.

After cancelling an wayward going print I've used I tried to move the print head from atop the current aborted print. For that I clicked on an empty area of the grid representing the print bed on the 5Dprint app. However, instead of just moving to that position it tried to push the print head through the side wall of the makibox. (to which I responded with an emergency shutdown). As it seems after cancelling a print, wherever the print ends parked is considered to be the new (0,0) coordinates.

After print finishes pressing [+] on bed moves it up instead of down.

First time I stopped the print and wanted to lower the bed so I could remove unfinished print. Pressing [+] moved the bed up resulting in hot end smashing into the print, deforming bed and finally getting free when I managed to move the head to the side. This deformed rods a bit, but luckily seems that it did not affect the printing quality.

When resetting / abandoning a print, the UI doesn't quite appear to go back to a proper "pre-print" state

After running one of the macro's for loading filament, it would appear the E position isn't fully reset.

That's a very...short readme file, not explaining

• what 5dprint is!!!,
• what 3d printer it is used for (Makibox HT+LT only or also other printers?),
• how to build it
• how to install and use it (what is required? Chrome? Go? How to install?)
• where the rest of the documentation is (supported g-codes? serial protocol documentation?)
