3D Prtined Arduino CNC Drawing Machine

Arduino Powered CNC Drawing Machine

3D Printed Arduino Powered CNC Drawing Machine

How to make a simple and high quality CNC drawing machine to draw on almost anything. I'll step you through how to build your own including all the files you need. Project video part 1 - assembly and electronics: https://youtu.be/XYqx5wg4oLU

This project has a relatively low cost and can produce some very detailed drawings. I've used it to create t-shirts, cake decorations, drawings to colour in myself (and some it coloured in for me!). You could also use it to draw out scale drawings, wedding invitations, birthday and Christmas cards and anything else you can think of. :)

cnc-drawingmachine's Issues

GRBL issues with CNC Shield from tutorial

When I got to setup GRBL on my arduino Uno with the CNC shield that I got from your video (amazing tutorial btw, very easy to follow), Im able to flash mi-grbl to the arduino and change the configs no problem. But when I tell it to home with $H i get the following:
Grbl 1.1f ['$' for help] [MSG:'$H'|'$X' to unlock] ALARM:8 ok
and the steppers just kind of whine for a little bit and don't move. I have double checked all limit switches, wiring and even used a different CNC shield but get the same result. Has anyone else run into this problem?

No motor movement

Hi, I tried building drawbot from the tutorial. Unfortunately motors only vibrate. I rechecked hardware (swapped CNC shield, couple of arduinos, drivers, motors). Apparently, the problem is software based, since with simple movement code everything works. I tried using other versions of grbl (deleting libraries of previous ones first ofc).
