Wainlux K6.... IOException: Port in use: COM3 #638

Open schmiernippel opened 2 years ago

schmiernippel commented 2 years ago

On my Wainlux K6 Laser i get this Error:

IOException: Port in use: COM3

A lot of people also get this error....

Any help or workaround??

greets

t-oster commented 2 years ago

Can you screenshot your device manager to confirm the Lasercutter is present on COM 3?

t-oster commented 2 years ago

You could also try to run visicut as admin

Is there any other program opened which uses the com Port?

schmiernippel commented 2 years ago

No....and i also have tried an other PC....and a get the same error...

schmiernippel commented 2 years ago

This Error i also get:

“IOException: Underlying input stream returned zero bytes”.

I will try changing the port....

schmiernippel commented 2 years ago

Changing the port will not help...

t-oster commented 2 years ago

Does it work with any other Software?

schmiernippel commented 2 years ago

Yes...it works with original software....and also with differen versions of the software!

schmiernippel commented 2 years ago

Is there anything i can do for you that you know what is not working??

t-oster commented 2 years ago

Hmm. Okay. Are you able to set up a development environment so we can debug step by step?https://github.com/t-oster/VisiCut/wiki/Development:-Getting-started

mgmax commented 2 years ago

Can you connect to the serial port using other software (HyperTerminal, Putty or similar)?

Can you find out which program blocks the serial port? https://www.equisys.com/Support/technotes/howto-identifying-which-process-is-using-the-serial-port

yes i can access the port with other software, checked with "serial port monitor from eltima software" it works also with original laser software

When i open visicut and send the code to the engraver, a can not connect with other software to the Port, so visicut it is connected to the Port.

Same “IOException: Underlying input stream returned zero bytes” here (Wainlux K6, VisiCut for Windows | 1.9-139).

Also getting this. Windows and K6. Is there anything we can do to help debug? I do have a logic analyzer, if necessary, although I don't particularly want to pop the top off the unit if I don't have to.

edit: This is in regards to "Underlying input stream returned zero bytes" continuing discussion in the proper issue linked below

mgmax commented 1 year ago

I'm somewhat confused by the comments - the original poster says "IOException port in use", another one says "Underlying input stream returned zero bytes". Please only discuss the "Port in use" issue here.

For the "zero bytes issue", see https://github.com/t-oster/LibLaserCut/issues/170 .
