[FEATURE REQUEST] Add support for pen plotters #273
Description
Is your feature request related to a problem? Please describe.
The ESP3D project has amazing flexibility. I would like to add support for hpgl pen plotters. These great machines are just too good to let die out. Adding the possibility of using these machines within the ESP3D framework would open up features such as wifi connectivity, SD plotting and all the other fantastic features that ESP3D has to offer
Describe the solution you'd like
The integration of hpgl commands into some of the panels such as JOG and status. The core features like the SD file system and terminal are already 99% usable and only need minor changes to use.
Describe alternatives you've considered
I had started a software that has similar features. It was not even nearly as stable as ESP3D . After looking at the ESP3D project I realized I was just trying to re-invent the wheel. The required changes have already been tried and tested so should be good to add to ESP3D. The changes to the UI would be very much within the framework of the existing ESP3D UI and would not require a total re write.
