A few weeks ago, I replaced Ubuntu on my laptop with Linux Mint Debian Edition (LMDE).
During this time, I haven’t been doing much printing, just waiting for the geared stepper and other parts. This also meant that up to now, I haven’t attempted to connect to the Cupcake via LMDE.
When I attempted to connect to the printer, ReplicatorG 24 could not find the USB-serial port, but the FTDI drivers were installed, and it was listed as /dev/ttyUSB0. Running ReplicatorG as root worked however.
Basically, LMDE (and I’m guessing a few other distros do this as well) does not allow users to access the serial port by default. To change that, enter the following command in the terminal console:
sudo chmod a+rw /dev/ttyUSB0
A few caveats here. I added myself to the sudoers list (by default LMDE doesn’t do that and you’d have to su , then enter the above command). And I hate to mention the obvious, but this assumes that your USB-serial port is listed as ttyUSB0. If not, just replace it with whatever it’s listed as (doing a ls /dev/ttyUSB* should give you a list).
Anyway, I hope this is of help someone out there.
