Bug Unable to connect to XYZPrinting Da Vinci Pro 1.0 on Linux via USB or WiFi/WLAN

[makerjrgn 0]

Hi, I'm new to Cura and to 3D Printing at all. I got a XYZPrinting Da Vinci Pro 1.0 Printer and I would like to use it with from my Linux Machine with Cura.

 

I installed Cura 4.13.1, added my Printer as a "Non Network Printer", choose the right model, but it doesn't show up in the Monitor.

 

Then I started researching...

 

By the way, I am on Manjaro Linux

 

uname -a
Linux NB03L 5.10.105-1-MANJARO #1 SMP PREEMPT Fri Mar 11 14:12:33 UTC 2022 x86_64 GNU/Linux

 

I connected the Printer via USB while watching at the "dmesg" output:

 

dmesg -w
...
[ 6457.857810] usb 1-2: new full-speed USB device number 12 using xhci_hcd
[ 6457.998983] usb 1-2: New USB device found, idVendor=11f1, idProduct=2520, bcdDevice= 1.00

[ 6636.800344] cdc_acm 1-2:1.0: ttyACM0: USB ACM device
...

 

so the Printer should be available as "/dev/ttyACM0" - let's start Cura ...

 

I tried to run via command line as "root" to avoid Permission issues and see debug output. From there I can see that Cura seems not to be able to find a proper Baud Rate:

Now this is running in an endless loop. - Any Ideas on that?

This seems to be a popular problem with the DaVinci printers.  Most searches come back with answers regarding Windows issues, but the same thing may be going on with Linux.  One fix that worked occasionally was plugging the printer in to different USB ports in the computer and then all of a sudden things came to life.  That would seem to indicate that the port driver only installed on one port rather than being available on all of them.

The "cache" size seems important as well.  Connections have been made with the DaVinci at a baud rate of 250k.  That is one of the rates that Cura checks.  FYI - it looks like Repetier Host has the same problem with the DaVinci's.

 

Since no Ultimaker printers use USB printing anymore, it is unmaintained unless someone from the community wants to take a shot at updating it.  The Octoprint/RaspPI combination seems to work well.

Hi, and thanks for your quick response.

I will definitively try different USB Ports. Maybe that works.

 

But how do you get to the following conclusion?

On the Projekt Website they don't even mention the XYZPrinting Devices - neither for being known working nor not working.

 

Thank you

That is a general observation since for most machines it's a viable alternative to Cura's USB Printing.

Questions about the DaVinci's come up here every once in a while and I tried to do some research to try to help.  It was like pulling teeth trying to find anything useful though.
