I flashed the GRBL firmware to the Uno by using the example sketch and Arduino IDE. Then I downloaded the Universal G-Code Sender here: https://github.com/winder/Universal-G-Code-Sender. It lets users easily send commands and G-code files to their CNC...
8. Choose the G-code file you’d saved from the Braille Rap UI, and select ‘Begin’. This sends the G-code to the CNC router that then begins to make the braille character impressions on the paper underneath.
sudo apt-get install gcc-4.8 g++-4.8 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.8 You can then check which one is set, and change back and forth using: sudo update-alternatives --config...
Finally, add any message you would like, and put the pack into a card-backed A5 envelope and post it!All the ones I posted weighed 104 g, combined with the thickness, this puts them in the 250 g bracket for Royal Mail's "Large Letter" - costing £1.26...
The Assembly Instructions for the PolyVent are too long to put here, but here is a link:https://docs.google.com/document/d/1g0reyAfZ0L1FvxNtxldv_rv06NfOP6shhV7HQqlzk-g/edit?usp=sharing
The Buildbotics Controller allows turning the spindle on using M3 and M4 G-Code commands and turning the spindle off using the M5 G-Code command. The spindle is only capable of turning in one direction. Speed control is achieved manually...
Repeat 8 times: take a BS170 NMOS and solder the S(ource), G(ate) and D(rain) pins to the board (S to the GND bus you've just made) and immediately solder a 10K resistor between the G and the S (or the GND bus). You can easily fit a transistor-resistor...
Click on the generated .gcode file, drag it and drop it on the provided Marlin Excellon Fix F100 Z.exe. This will patch the generated to G-Code to move the drill in the XY plane at F100 speed. As of FlatCAM 8.991 beta, it locks the XY speed to F3.0 without...
The power on/off battery was pretty much following another guide. I think I used physical pins 5 and 6. If you want to be clever you should add a quick connect so you can connect your button to the Raspberry Pi header so it's easy...
I added an on/off button using the instructions from: https://howchoo.com/g/mwnlytk3zmm/how-to-add-a-power-button-to-your-raspberry-piI use this switch from Amazon because GRTA :) https://www.amazon.com/dp/B07SRGG7KF?psc=1&ref=ppx_yo2_dt_b_product_details...
