So, I’ve got a 3D printer and for at least two months since a fresh install I’ve done the thing that we’ve all done when we can’t be arsed to sort out permissions – IE; run the app as sudo. That’s precisely what I’ve been doing to have Pronterface ‘see’ the 3D printer and thus be able to control it.
Well, I got tired of doing that yesterday and dragged up a memory from when – I think – I needed to get VirtualBox talking to USB to see my Garmin device for map updates. It’s pretty simple. Just add yourself to the ‘dialout’ group.
AND FOR THE LOVE OF ALL THAT IS HOLY; LOG OUT AND LOG BACK IN AGAIN FOR THE PERMISSIONS TO TAKE. (Otherwise it won’t work; and will mysteriously spring back in to life the next time you reboot your machine and you’ll have forgotten what you did and it’ll appear like magic)
