Polargraph Controller v1.8 adds a more representative pixel density preview style to the controller app:

Edit your properties.txt file and set controller.density.preview.style=5

or set controller.density.preview.style=2

These new modes are designed to give a better idea of whether pixels are going to fall off the page. That’s really annoying when it happens.

I’ve also taken out a couple of buttons that didn’t really do anything sensible any more.

It’s available here on the github page.

Also included in that bundle is v1.9 of the polargraph_server_polarshield firmware. This is really only intended for the new v2 polarshield, but should do no harm if you want to play with it. Well, I hope it doesn’t do any harm anyway.

The only new feature is that the pen-lift height (at up or down points) can be adjusted through the touch UI now, rather than just through the controller app.
