# Help for Jog and Learn Router Wizard

This wizard will allow you to jog a machine around and create a Gcode file from the movement. This would be usefull for copying an existing part instead of measuring and drawing it.

This wizard always writes to the same file, C:\Mach3\GCode\teach.tap This allows you to add to an existing file. If you want to start a new file be sure to click the 'NewTeach File' button.

Inside the wizard you are free to move the machine around with the normal jog commands, as well as by entering commands into an MDI box. Your movements are only saved and made part of the G code file when you press one of the action buttons.

There are several groups of action buttons.

## Control functions

These simply add control statements, like spindle on or off, tool change, etc. Pressing the button will add that code into the Gcode file.

Note the button labeled 'Insert Comment' You may use it to add any comment into the Gcode. You might use a comment to indicate a point in the code where you want to insert another block of code. For example, if you have a long line of holes to drill you might just enter the first hole and the last hole, with a comment in between, then use another wizard to generate all the code for the holes between these points.

## Movement Buttons

In general, you may move around the machine freely with any of the normal jog functions, then when you are at the desired point you press a movement button when you are at a point you want in your program.

### Radid Move

A rapid move will create a G00 code to the current point. X,Y,and Z values are used. Be cautious if you rapid to a Zvalue below the surface of the part!

### Feed Move

Create a G01 command to the current position. The current Feed rate will be used.

### Arc Move

An Arc, or a full circle move may be generated. To enter an arc you must first move to a point that defines the start of the arc with either a Rapid or Feed move. Press "Start Arc' to remember this point. Next move to a point on the arc, and press "2nd Point". Finally move to the end of the arc and press "end Arc". If the 'Full Circle' button has been pressed, and its LED is on, then a full circle will be generated. Otherwise an arc from the start to end points is generated.

For best results place the 3 point around the Arc about equally.

### Holes

Move to the center of any hole and select a Rapid or Feed move. Note that this move should be above the work at a safe height. Then select the kind of hole.

Hole will mill a hole by making a circular cut. The tool will spiral down to the requested depth, then make a full circle at that depth to fully clear the hole. Be sure you are using a cutter that can be plunged!

Drill Hole G81 will make a plunge drill operation to the selected depth.

Peck Drill G83 will make a peck drill cycle to the selected depth in steps of Zinc.
