Need help with LaserWeb on Ubuntu. Can’t get pass com port errors.

Did you install it like this:

Scroll down the readme until you get to the ubuntu install instructions

Also, what type of controller card is you machine running?

I used that exact guide. While not a Linux person, I’m pretty confident in dealing with Arduino COM port issues on Windows. I have it installed and running. I can load the interface in the web browser and it seems to at least see that the port active and let’s me select it, but as soon as I go to control, I get a communications error. As for the Controller Card, I’m running an Arduino Mega running Marlin. The Controller setup seems to be working. I can load a Gcode file from SD card and it seems to process it.

When I get home, I’ll plug it back in and get the exact error. I thought I had it saved on my phone, but can’t find it. Thanks for your assistance

I went to get the exact error message to post here. When i did that I realized that I had not tried to run the Server as the “root” user. When I switched the Terminal to root and started the server, it seems to be working. I guess only the user I was running under does not have permission to access the USB/COM ports. I currently have the Ramps controller spinning some spare Stepper Motors and it appears to be turning them correctly and I can see Position indicators on the LCD screen changing.

Thanks for the responses
