+# Week 1 Manual Control
+
+In week one, students dive right in and learn manual control of the CNC milling machine.
+
+Starting with the desktop 3018, students learn the parts of the machine and what they do. 
+
+Concepts introduced include:
+
+* X, Y, Z planes
+* Gantry, spindle, stepper motors
+* Spindle clearance
+* Gcode
+
+**Exercise:**
+
+Install the manual offline controller on the 3018. Use it to control the x and y movement of the gantry and bed. Learn to adjust speed control for the motors as well as the spindle.
+
+Students now return to the smaller desktop machine for the manual cutting example. Concepts introduced include:
+
+* Collets
+* Spring clamps
+* Bit properties
+* Chip load/spindle speed
+* Spoilboard
+
+**Exercise:**
+Learn to use clamps for securing material to the bed of the machine. Using XPS foam, students can get used to manually cutting using an offline controller.
+
+## Large Machine Introduction
+
+Repeat the same exercise on the larger Omni CNC milling machine. Students should all get a chance to control it. Additional concepts introduced for the larger machine include:
+
+* High/Low speed controls
+* Distance setting
+* Homing on startup
+
+Students should have an understanding of the importance of manual control of the machine, when it will be used in each job they do.
+
+**Exercise - Manual Calibration**
+
+Play the targetting game to learn how to manually position the tool head as you would do in setting an Origin Point.
+
+
+
+Students then secure a piece of hardwood to the CNC bed using spacers for surfacing. Each should get a chance to manually surface the hardwood using a surfacing bit.
