The button connect to printer does not work

Tiki812

Hello,

I have already checked othe discussions in the forum but no problem seems to be similar to myne

I am trying to connect my 3D printer My Creator 2 to the program Repetier-Host version 2.2.4

I am using an AppImage running only once, i.e. by the SW Repetier-Host-x86_64-2.2.4.AppImage.

The button "connect to printer" does not work, I have tried to change some com parameters, but no change.

The USB is connected to the printer by /dev/ttyUSB0, bit rate 250000 and so on.

All other commands of the GUI work well, only this button shows some problem

Do I have to install the AppImage SW definetely on PC or something else?

In the past I had no problem to connect the Repetier-Host to the printer, I used the version 2.0.5 but not the AppImage version...

many thanks in advance for some feddback

C# on linux has issues with non ansi baud rates. So to select 250000 we connect then call an external c++ software and that normally works. But maybe it has a problem on your linux, e.g. a library missing or your linux is 32 bit. You can check it probably if you start it from terminal so you see error messages in the terminal what might give a hint.

You can also try to switch printer to 115200 so it uses a ansi baud rate that c# can handle it self.

Other solution which is also better is to install Repetier-Server and connect printer over that. In host you then use Repetier-Server Connector instead of serial connector to connect. The server also has no issues with 250000 baud and you can even close host while printing and printing still continues.

Hello,

thanks for the prompt reply.

My linux is of course 64bits, furthermore I had no problem with an old version of Repetier-Host :-(

I will check it and then I wil inform you if that works

Hello again,

first, I changed bit rate, e.g. 115200 or other but no improvement noted.

Then, I tsarted the AppImage program from the terminal and attached the messages generated after running the program:

Can these messages help solve this matter?

The serial ports belog to group dialout, but apperently the user running the host does not. So that is a simple issue as it seems. You need to add group "dialout" to your user.

Hello,

now it is works.

By the command :~$ sudo adduser <user> dialout then with restart it was possible to connect finally the program Repetier-Host to the 3D printer

Again many thanks for the support
