Frequency Tester

Frequency Testing

This will allow you to test a specific frequency that you hear when you do your resonance testing in Klipper and potentially track down where extra peaks are coming from. If something is rattling at a specific frequency, you can specify that frequency and feel around the printer until you track it down.

Code was adopted by zifnab from somewhere in Klipper.

Usage

You have to have [resonance_holder] in your printer.cfg.

The command is HOLD_RESONANCE AXIS=<axis> FREQ=int SECONDS=<seconds>

How to use Boostrap 3 input-group in Simple Form

Finally, Simple Form support Boostrap 3. 👏

But I found it still dosen't support some components in Bootstrap 3. Or may be in the future. But I can't wait, so I find a solution to support them. It was inspired by heartcombo/simple_form#531 (comment) .

This is a final solution and I used in my project.

Notes from running Dokku on Digital Ocean.

My notes for Dokku on Digital Ocean.

Commands

Install dokku-cli (gem install dokku-cli) for a more Heroku-like CLI experience (dokku config:set FOO=bar).

# List/run commands when not on Dokku server (assuming a "henroku" ~/.ssh/config alias)

ssh henroku dokku
