Anet A8 printer does not connect to cura

[Ian64 0]

I can not connect to my anet a8 pritner. In Ponterface the pritner connects but in cura it does not.

With Cura running, select "Market Place" at the upper right of the screen.  When the dialog comes up (it can take a bit of time to load) select "Installed" and scroll down to "USB Printing" and make sure it is checked.

You can also do a search around here for the same topic but with different printers.  The problem does come up once in a while and there might be a couple of other things you can look at.

I solved the problem in my situation. I have Windows 10 and Anet A8 printer.

I looked a Python script:

C:\Program Files\Ultimaker Cura 4.10.0\plugins\USBPrinting\AutoDetectBaudJob.py

There is a loop where Cura sends "M105" gcode to the printer and waits response.

                while timeout_time > time():
                    line = serial.readline()
                    if b"ok" in line and b"T:" in line:
                        self.setResult(baud_rate)
                        Logger.log(... 
                        serial.close() # close serial port ...
                        return

 

But "ok" and "T:" are not on the same line. That's why the condition never come true. I made a change like that:

                line = b""
                while timeout_time > time():
                    line += serial.readline()
                    if b"ok" in line and b"T:" in line:
                        self.setResult(baud_rate)
                        Logger.log(...
                        serial.close() # close serial port ...
                        return

 

No other change was needed. The connection begun to play.

If you are on a Windows system you might have to "share" the folder with yourself.  You might also have to alter the "Security" setting to allow yourself access to the folder.

Right-click on the main Cura installation folder and select "Properties".  On the "Security" tab make sure you have access to alter items in the folder.  On the "Share" tab, share the folder.
