Inject temp commands (m104) to adjust temp according to the volumetric flow rate per layer

GCode temp tweaker

Sometimes, layers are so small that they need to be printed more slowly so the layer has time to cool down. But slowing down the feedrate causes the filament to be cooked inside the nozzle. This tool will process the gcode, calculate the overall volumetric flow rate per layer and adjust the temp accordingy. This is achieved by injecting temp commands (M104) in to the gcode.

How it works

• go to https://gcode-temp-tweaker.firebaseapp.com/
• drop a gcode file into the rectangular box

- set the minimum and maximum temp you want to vary between

• notice the table that reports the temp changes that will be injected

• download the resulting gcode!

Know issues

• the absolute extrusion speed are off (but the resulting temp changes, which are based on relative speed changes, are surely usable)

Running locally

Install the dependencies...

npm install

...then start Rollup:

npm run dev

Navigate to localhost:5000. You should see your app running.

By default, the server will only respond to requests from localhost. To allow connections from other computers, edit the sirv commands in package.json to include the option --host 0.0.0.0.

Building and running in production mode

To create an optimised version of the app:

npm run build

You can run the newly built app with npm run start. This uses sirv, which is included in your package.json's dependencies so that the app will work when you deploy to platforms like Heroku.

Single-page app mode

By default, sirv will only respond to requests that match files in public. This is to maximise compatibility with static fileservers, allowing you to deploy your app anywhere.

If you're building a single-page app (SPA) with multiple routes, sirv needs to be able to respond to requests for any path. You can make it so by editing the "start" command in package.json:

"start": "sirv public --single"

Using TypeScript

This template comes with a script to set up a TypeScript development environment, you can run it immediately after cloning the template with:

node scripts/setupTypeScript.js

Or remove the script via:

rm scripts/setupTypeScript.js

Deploying to the web

With Vercel

Install vercel if you haven't already:

npm install -g vercel

Then, from within your project folder:

cd public
vercel deploy --name my-project

With surge

Install surge if you haven't already:

npm install -g surge

Then, from within your project folder:

npm run build
surge public my-project.surge.sh
