AtomCNC – CR1 for Revision 1

Compiling

To Compile modify the MAKEFILE:

change this to your arduino bin folder
ARDBIN = E:\arduino-1.0.1\hardware\tools\avr\bin

change this to match your com port
ARDCOM = COM5

When done compiling you should see a AtomCNC.hex file.

Uploading

To Upload simply run UPLOAD.bat.

Grbl – An embedded g-code interpreter and motion-controller for the Arduino/AVR328 microcontroller

Grbl is a no-compromise, high performance, low cost alternative to parallel-port-based motion control for CNC milling. It will run on a vanilla Arduino (Duemillanove/Uno) as long as it sports an Atmega 328.

The controller is written in highly optimized C utilizing every clever feature of the AVR-chips to achieve precise timing and asynchronous operation. It is able to maintain more than 30kHz of stable, jitter free control pulses.

It accepts standards-compliant G-code and has been tested with the output of several CAM tools with no problems. Arcs, circles and helical motion are fully supported, as well as, other basic functional g-code commands. Functions and variables are not currently supported, but may be included in future releases in a form of a pre-processor.

Grbl includes full acceleration management with look ahead. That means the controller will look up to 16 to 20 motions into the future and plan its velocities ahead to deliver smooth acceleration and jerk-free cornering.

Changelog for v0.7 from v0.6:
– Significantly improved and optimized planner re-factoring.
– New robust cornering algorithm, enabling smoother and faster motions.
– Arc acceleration planning enabled by efficient vector transformation implementation.
– Stepper subsystem re-factoring to help remove some motion issues from pre-v0.7 builds.
– Increased dwell times.
– G92 coordinate system offset support.
– (Beta) Limit switch and homing cycle support.
– Many other bug fixes and efficiency improvements.

Important note for Atmega 168 users: Going forward, support for Atmega 168 will be dropped due to its limited memory and speed. However, legacy Grbl v0.51 "in the branch called ‘v0_51’ is still available for use.

The project was initially inspired by the Arduino GCode Interpreter by Mike Ellery

atomcnc's Issues

Driver will not install under Windows

Cannot install this hardware.

atomcnc

An error occurred during the installation of the device. the parameter is 
incorrect.

[attachment=0]atomcnc-error.jpg[/attachment]

I didn't get a chance to set any parameters.... Just pointed the New hardware 
wizard at

slabvcp.inf

What do I do to get this connected? Is there some other driver I could use?

Trying to install into a Fujitsu Stylistic ST-4121 running Windows XP Tablet PC 
Edition, SP3. Is there a log file or something I could look at?

Windows | Control Panel | System | Hardware | Device Manager

shows AtomCNC under Ports (COM & LPT) w/ a yellow exclamation mark and the 
dialog says the driver isn't installed. How do I get it installed?

Disagree no docs necessary

What steps will reproduce the problem?
1. Buy a Shapeoko which is supposed to be complete off eBay
2. Try to get it assembled, find that it's missing wires, zip ties, mounting 
brackets, wires and power cable
3. Search for a copy of AtomCNC.pdf, but not find it

What is the expected output? What do you see instead?
A working Shapeoko. A pile of junk.

What version of the product are you using? On what operating system?
The one provided. Not at the point where that matters.

Please provide any additional information below.
I _really_ want a copy of the documentation so I can get this machine which I 
paid for working.

Available drivers will not install --- this one did
