cool foam cutting CNC build

Posted on September 14, 2018 by robertwilkie

The author calls it a 4 axis CNC, which is kindof right..more 3.5.  Either way its a nice build. https://www.instructables.com/id/4-Axis-CNC-Hot-wire-Foam-Cutter-ArduinoRamps14/

Convert a windshield wiper motor into a servo

Posted on August 16, 2018 by robertwilkie

Servos are expensive for a motor, so if you need a big one, this is a nice alternative to buying one.  The author uses a windshield motor, pot, an arduino, to build one. Supersize DIY R/C Servos From Windscreen Wipers

GRBL ported to ESP32

Posted on August 15, 2018 by robertwilkie

Never really thought about it, the ESP does have more process/capacity than the Arduino UNO, and its wireless, so it makes sense to use.  I will have to look more into this in the future. Grbl Ported to the ESP32 … Continue reading →

Make a Braille Printer

Posted on June 5, 2018 by robertwilkie

In addition you can use google text to speech with it.  Pretty neat build overall using parts thought the author bought all the parts (from the looks of it you would think it was scrap material). http://www.instructables.com/id/Simple-Braille-Writer-Speech-to-Braille/

Sound proofing a CNC

Posted on May 23, 2018 by robertwilkie

I like the authors idea but…what about ventalation, metal chips getting in the way, or…lets see hot metal in a wood box….maybe a fire issue? I agree thought CNC’s are noisy buggers. https://medium.com/teelebee/cnc-box-d13eaa7c0f36
