USB debugging Linux

MrMakerSteve

Hi,

I've got 2 Printrbots, both of which work fine on my Mac (just not at the same time...) I had a spare pc running linux (Lubuntu 15.10) so I thought I'd try to make it work...

-I installed RepetierHost v1.6.1. It launches fine from desktop or from terminal

-I connected Printrbot to pc via usb and plugged in power. The green light came on the printrbot board.

-I pressed "connect" in RepetierHost and I do not get a connection.

-- I am part of the dialout group

-- I get this error message:

steve@steve-desktop:~$ Opening serial failed on second try:System.IO.IOException: No such file or directory

I've been trying to read about this... Is it a "mono" issue? (mono v4.2.0)

I've tried different cables and usb ports.

The USB ports are individually tested with a mem stick - I can xfer data to/from stick on all ports.

Cables individually tested  and work for Printrbot/Mac connection.

How can I get rH to see my printrbot? 

Thank you

Steve

 Opening serial failed on second try:System.IO.IOException: No such file or directory

means the port is not available or written wrong. What did you use as port name? Must be something like /dev/..

SOLVED -

First, I verified new connection was dev/ttyACM0

Then, per suggestion from http://askubuntu.com/questions/58119/changing-permissions-on-serial-port:

Try going into System / Users and Groups and checking the box on your username in the TTY Group.

This allowed ttyACM0 to show in RepetierHost. Once this was selected, I was able to connect and control machine.

Thank you

Steve
