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. | |||
