Cancel plot?

Is there an option to pause / cancel current plot?

Is it possible to show a HPGL Preview?

Hello,

is it possible to generate a preview with hp2xx or so? I know whats to do in Linux but not in this Webfrontend. Can you help me to display a image? Generation can be done direct after generate hpgl.

Server doesn't load

Hi!
After running the install on a RPI400, which seemed to go fine (the device rebooted by itself), I'm unable to connect to the website - it just doesn't respond on port 5000. Is there any way to debug this? Does it generate logs anywhere (I was unable to find any)?

User must be pi

Hello,

for documentation: You should start it as user PI in his root folder. The startscript links to ~pi.

svg conversion fails silently

Hi-

Installed on a fresh Pi Zero W with all updates applied. Uploading an SVG works fine. Clicking on convert look like it work, as an "exported" message pops up and the status windows states the svg has been deleted, but the hpgl file does not show up in the file uploaded window.

Any suggestion on how to debug this?
