Using two printers simultaneous - OSError: [Errno 11] #63

Closed Henke1983 closed 4 years ago

Henke1983 commented 4 years ago

I want to be able to use more than one printer in one Raspberry Pi to drive Klipper. I have successfully installed DWC2-for-klipper with the modification that needed. The printers have different port-numbers to connect to, and they are possible to use.
The guide I followed was this one : https://klipper.info/klipper-+-dwc2-1/installing-dwc2 In there is some code that are inserted into the gcode.py file. This is located at row 324. So in the dwc2 I don't get any feedback on the second printer in the gcode-console. It's just a spinner waiting for feedback from printer(on the send button) The printer on port 4750 works fine. The printer on port 4760 works - but after some commands I get OSerror.

The error from Klippy2.log. Write g-code response Traceback (most recent call last): File "/home/pi/klipper/klippy/gcode.py", line 324, in respond os.write(self.fd, msg+"\n") OSError: [Errno 11] Resource temporarily unavailable

Can you help me sort this out - because then I can connect additional printer to DWC2 and Klipper. Is it any more information needed. klippy2.log

Two instances of Klipper with dwc2 are running just fine. Please make sure you sorted the paths for both instances out correctly.
