[[File:CNC_Mill.jpg|thumb|Hacksburg DIY CNC Mill]]
Hacksburg's mill is a Jet JMD-15 Mill/Drill with a 1HP motor and R8 collet. It is a rebadged Rong Hu RH-30, and more information may be availible online for that model. A very basic overview of the mill and some safety information can be found in the [[:File:Hacksburg CNC Milling Class.pdf|Milling Class Slides]].
The mill was converted to CNC by adding Kollmorgen NEMA34 stepper motors (Model CTP32NLF99KAAOO) to the X, Y, and Z axes using custom mounts. The motors are powered through DM860 micro-step motor controllers controlled by Grbl running on an Arduino Uno.
== CNC Milling ==
Our CNC mill is controlled by [https://github.com/gnea/grbl/wiki Grbl]. When your CAM software has an output option for grblGrbl, use it. Otherwise, grbl Grbl understands LinuxCNC/MachineKit G-Code and you can use a setting for that.
If you have neither option, you can use a generic setting. LinuxCNC/MachineKit try to obey standard G-Code.
== User Interface ==
The mill uses [https://github.com/vlachoudis/bCNC/wiki bCNC] for DRO, manual jogging, and g-code sender.
=== Manual Jogging ===
{| class="wikitable"
|-
! Setting excessively high jog size can cause commands to be buffered and the machine to crash! Do NOT set jog step higher than 0.5 mm or 0.02 inches!

== Feeds and Speeds ==
* Aluminum
** 1/4" two-flute endmill, 1400 RPM, 4 IPM works well. Feed rate is limited by machine vibration.
