=== Set up the material ===# Clean off the material (also known as "stock") as well as the location on the bed where you'll be affixing it.# Apply tape to the side of the stock that will be placed on the bed.# Place and firmly press down on the stock on the bed.

The [[Bantam Tools PCB Mill]] is a 3-axis CNC mill - a [[Manufacturing techniques#Subtractive manufacturing|subtractive manufacturing]] machine. Fabricating with this machine is relatively simple, thanks in large part to its well-developed and maintained [[CAD and CAM#Software|software]]. The process consists of only three steps:
#Set up#Mill#Clean up == Set up == # Set up the machine# CAM the object# Set up the material# Set up the (initial) tool ===Set up the machine=== #Turn on the machine#Home the gantry ===CAM the object===
=== CAM Set up the object material===# Import the CAD design# Position the design# Select the appropriate material and tool(s)
=== Set up the (initial) tool ===This can be done through software prompting.
#Use the provided wrenches to hold the spindle in place while loosening the collet nut. You’ll notice two clicks before the previously inserted tool is released. If possible, use a finger to hold on to the tool while loosening so that it does not fall from the collet.#Insert the new tool and tighten with the wrenches until snug (you don't need to go crazy).#Indicate which tools you have available through the software menu.#Click Locate Tool and watch as the software automatically locates the tool. == Mill ==
Press the "Mill all visible" button. Make sure to pay attention to the machine, since if a tool is broken, noticing it sooner rather than later will save you an immense amount of headache.
== Clean up ==
Make sure to always leave the machine cleaner than what you found it! Vacuum up any and all [[wikipedia:Swarf|swarf]] created by the milling process.
== Milling considerations ==Try to minimize the number of toolchanges tool changes while optimizing the paths of the selected tools; that is, small tools for precision work, large tools for removing areas of the material.==Workshop checklist=====Learning Objectives===By the end of this Workshop, you should: #Know the different parts of the mill, and which parts are dangerous.#Understand the differences and advantages of available tools.#Understand the differences and advantages of available stock. ===Measurable Outcomes===By the end of this Workshop, you should be able to: #Control basic machine functionality.#Load stock into the machine.#Load a design into the software, and position and adjust its attributes.#Change a tool.#Mill an object from a design.#Effectively clean the machine.
