Does the Silhouette Cameo 4 Plus works with this script?

[Counterfeiter]

Has anyone tested this successful with this plotter?

What are the necessary steps to debug this?

I recently got a Cameo 4, but I haven't been able to get it to show up and a network shared printer in windows 10, so I haven't been able to send the output to it from gerber2graphtec.

Anyone know how to do that? I can only get the Cameo to show up under "USB Printing Support"

Silhouette Portrait 3 not working (

For the Cameo 4 and the Portrait 3, can anyone capture the traffic sent to the device using the proprietary tools (with simple artwork such as a single rectangle)? If the command set is similar to prior devices, I can make what small changes might be required. If the API has totally changed, then things are less certain unless the API is reverse-engineered or otherwise becomes known.

Other forks of this software may have made progress here as well

Thank you!!! I tried to intercept the stream in win10.. Tell me the name of the program, how can you intercept then win\linux?

This is what sends Portrait 3 when using silhouette studio

With this utility, the plotter is determined by a jerk of the head and the data is transmitted by the LED flashing but it is in place.
pmonta tomorrow I will try to disassemble and connect usb uart + PuTTY

Good to know that the Portrait 3 can be driven by py_silhouette and that its command set looks very similar to prior devices. Let me see if it's easy to extract any Portrait 3-specific information from py_silhouette (or you can do so if you like---patches welcome). That library might be a good basis for the entire back end of the Gerber tool if it tracks the newer hardware.

I also found some recent information on the Silhouette command set here:

https://github.com/fablabnbg/inkscape-silhouette/blob/master/Commands.md

It includes some discussion of the Cameo 4 Pro at the end.

Unfortunately I'm not a programmer and I really hope for your help... Because the plotter got up

Running the test:
Important! Print the test page /git_repos/clone/py_silhouette/test/test_sheet.pdf or /git_repos/clone/py_silhouette/test/test_sheet.svg.
Install a test page in the plotter.

1. cd ${HOME}/tmp/test/py_silhouette
2. export PYTHONPATH=${PYTHONPATH}:${HOME}/tmp/test/py_silhouette
3. in the terminal, run:
   python3 test/test_sheet.py
   Follow the instructions.
