Quick slicer update

I added a lil thing for you to be able to set a custom print speed. I also added integration and a fallback system to the printer.

guh

im so close to finishing this!

Slicer stuff

I refactored the slicer scripts and then made a cool tkinter GUI. You can move around your SVG(Sadly you cant print multiple at the same time).

Printer stuff

Using tkinter, I added a load button so you can load your .banana files way faster than using command line arguments.

Whats next?

• Better sprites for 2d printer app
• Get ready to ship(pls get me out of the depths of python)

more stardance logos!!! =D

GUI time!

I tried to fix my slicer issues, but that was a waste of time. I then fixed an issue present in the older versions of the slicer where the printer would begin extruding for infills before it reached the X Y coordinate of where it should start infilling. The slicer struggles to do really complex images howver, but I am okay with that because even being able to slice was a big challenge for me to complete.

Whats next?

• Basic GUI
  • Move around print
  • Allow user to load custom SVG’s

Quote of the devlog

guh…

Bottom tier 2D printer moment

The slicer is absolutely NOT cooperating. I made two versions, each of which are better suited to different scenarios.

SlicerV2(left logo) Good when across the x axis, there are multiple points

SlicerV3(right logo) Good when there are multiple points along y axis.

They both are kinda bad, but I did optimize the slicer a bit. When from 35 elements/sec to around 25 elements/sec. Slicing still kinda takes a while though

send food pls, im hungry

it made stardance logo(trust i should get an award for this)

This was a result of TONS of tuning(took like 50 min, but ig hackatime doesn’t support my slicer =p ) The printer needs some work on when to start and stop extruding.

im not gonna put a whats next here, i made like 3 devlogs today 😭

my 2d printer finally printed its first picture =D

slicer takes forever to slice it though, so I need to optimize it

Whats next?

• Slicer stuff
  - Faster and better
  - GUI

The intelligence of my slicer is now not 0

I took a lot of time rewriting the slicer’s infill methods, and now the slicer can print objects that aren’t squares. I also added padding so the image you print isn’t crammed into the corner

Whats next

• testing with more advanced svgs
• GUI slicer

My image slicer is finally working =o

I finally got the slicer to start giving me sliced files(only took like an hr =D )
The first image is the image i am supposed to get, but the next image is what i got lol. I still have a lot of stuff to do to get the slicer working better.

Whats next?

• add padding so that im not printing on the edge of the build plate
• fix the slicer infill issues
• add padding to slicer infill extrusions
• try actual SVG images
• GUI slicer:
  • Allow user to move around pieces on the build plate
  • Make settings like printspeed and stuff load from sliced files

SVG stuff =D
I finally made a basic SVG shape extractor. It uses the svgelements python library to get information about svg images.

The next step will be making a basic slicer, which will be able to use this information to “slice” the svg into a .banana file for the printer. Infill is gonna be annoying to implement though.

I finally decided to put this project on stardance. Currently, you can print simple drawings(very annoying to slice them). The printer works like this:

1. Sliced files:
   • Takes an argument from running to run a .banana file
   • Interpret and convert back into commands that the printer can understand
2. Renderer and movement
   • Python class stores x y info with a bunch of other stuff to send to renderer
   • Interpolation between points
3. Printing
   • Using pygame permanent canvas that doesn’t get erased when pygame.flip() is called.

Features as of now:

• Printing =0
• Toolhead path preview(“T” key)
• Make printhead slightly transparent(“shift” key, allows you to see the rest of the drawing if the printhead covers any part of it)
• Test path(runs path but doesn’t print and goes way faster)

Currently printing is pretty finished. The next goal will be making a slicer that slices scalable vector graphics(svg) into .banana files
