Error opening port /dev/ttyusb*

Hi there,

I have a problem with RepRap host software (Windows Version), when I try to run the host software it keeps saying that "Error opening port: /dev/tty/usb3". Therefore, could I please have your suggestion? What should I do now?

Thank you very much

The problem is fixed!!!!


Thank you very much indeed

Same problem. Same solution.

Thanks

Same problem, solution not working for me - downloaded latest software/etc, using an Arduino Duemilanove as the interface.

Windows 7, 64bit, JRE6, quad monitors (may be related to graphics container error below)

I open the .bat file, and get:
Error opening port: /dev/ttyUSB0
and a pop-up:
"
Error in the main GUI: java.lang.IllegalArgumentException: adding a container to a container on a different GraphicDevice
[ok]
"
Clicking OK opens things up but obviously not working. I know, I know, you're already hitting yourself on the head and hammering out that I didn't change my port setting in the reprap.properties file (BTW, other complete noobies out there, you have to delete the *.dist from the end of the files!) - I did, have a look:

. . .
MovementSpeedZ(0..255)=240
MovementSpeedZ(0..255)=240
NumberOfExtruders=3
NumberOfExtruders=3
PathOptimise=true
PathOptimise=true
Port(name)=COM4
Port(name)=COM4
RadiusFactor=0.7
RadiusFactor=0.7
RememberWindowPosition=false
RememberWindowPosition=false
. . .

My USB converter is on COM4 according the the system, but the RepRap software doesn't appear to be reading this file for my com port. Any ideas? I was able to program the motherboard over my Arduino without issue and now have a very annoying bright red light :-) so that shouldn't be any issue
