DWC2 does not start #77

Closed icstra closed 4 years ago

icstra commented 4 years ago

I’ve already installed Klipper and dwc2 on a virtual machine running Raspbian and all is working perfectly. Now ,I’m trying to install that on a Manjaro distro and I get some troubles. Klipper has been installed from AUR and run perfectly well. I’ve installed also dwc2-for-klipper following instructions as I did for my Raspbian installation. Results : I cannot connect on 127.0.0.1:4750 as precised in printer.cfg. I’ve noticed that in the Raspbian install, reading the logs, I can see that dwc2 connect to 0.0.0.0 ( a line between extruder and serial connection). In the Klippy.log of Manjaro, I cannot see that line, concluding that the server does not start. I do not have any error messages in the logs. Thanks for your help since I know that dwc2 for Klipper runs well on your Arch machine.

Thanks for reply. After checking, it looks like my files already get these modifications. I’m investigating now on ports opening.

If you have AttributeError: Printer instance has no attribute 'try_load_module' in klippy.log and fresh klipper try to change line 49 in file web_dwc2.py from self.stepper_enable = self.printer.try_load_module(config, "stepper_enable") to self.stepper_enable = self.printer.load_object(config, "stepper_enable")

Thanks for reply. I had already change that line. I ´ve noticed that the symlink dwc2 to klippy was broken. I ´ve fixed that. Then I got an error message from dwc2 ( meaning that link was restored) telling me that /temp/printer was missing. So, I checked in my Raspbian and indeed there is a file named printer in tmp. Unfortunately, this file is not there in my Manjaro installation. I commented the line in dwc2 and the web server pop up in my browser. So, I progress. Of course, without serial instance, I cannot connect to my printer. I don’t understand why this file is missing. Finally, I found a walk around . I modified dwc2.py and replaced /tmp/printer with /dev/pts/0 and all seems to run. I can connect to web server and just tried a homing which well achieved. Will try later if all other functions are running well. For information, all is working with 2.1.7 dwc2. Thanks to all for your help.
