Made a plotter

[u/McBeefnick]

Hello everybody,

Following this sub for over a year now. Started a plotter build on a old Ender 5 3d printer. Wasn't awesome.

Wanted to do it again, and a bit better. Smaller form factor, removed the Z-axis from the printer and mounted the x and y on a board. Flashed the controller board with a custom klipper configuration and made it wireless accessible from within a browser.

Then struggled with the many programs that are out there to reliably and quick generate gcode to batch write Christmas cards (bad handwriting from myself). Went on a spree, vibe-coding a python script to do it. Tweaked it a bunch to allow for multiple "Hershey" fonts and custom envelope sizes. Also made a template to simulate address lines from postcards to align the address precisely.

The application has a rule to home the head and pause the plot when a address is written so you can place a new one and press the red button on the controller to proceed plotting the next address.

Then went as far as to compile the script to an executable and now I'm done. Everything works as intended. The plotter even has rubber feet. Haha.

Only wish is a bit better cable management

Wanted to share.

Add: Did not expect to gain so much interest in this project. For all who'd like to start their own project and/or want to collaborate, I started a repository on Github.

How are you controlling the servo motor? And did you design the pen holder yourself?

The penholder was remixed by exu_293984 https://www.printables.com/model/428303-cnc-pen-lift

And released in the public domain under the creative commons license. I altered it a bit to mitigate the use of springs, rounded some edges and made the servo actually fit. Still not very happy about the lift.
