Try a Circle
• Do a 6" circle using the built-in circle command: [CC] 6 (The 6 is the only parameter
you will need to provide on the ’Fill-In Sheet’ that comes up). Your ShopBot should
execute a smooth 6" circle.
• Note that the speeds of the motors change as the tool moves through the circle. The
motor speed changes in order to maintain a constant vectored speed at the cutter.
Do an 'Air Cut’ of a ShopBot Part File
Now let’s try running a Part File (a file containing cutting instructions or ‘tool paths’). We will
do an ‘air cut’, which means to run it in the air above the cutting bed without the router or
spindle running.
• Use: [FP; 'F'ile 'P'art], then use the arrow keys to scroll to the file called
"S_SBLOGO.SBP" and hit ENTER (If you aren’t in the c:\SbParts folder, you will need
to browse to it). All the files which start ‘S_’ are sample files of one sort or another …
you will probably find them interesting and helpful. Use the [‘F’ile ‘E’dit] Command to
check out what’s in them.
• We'll ignore the parameter settings on the fill-in sheet for the moment ... just hit
ENTER twice again to start air-cutting the file.
• This file cuts the ShopBot logo (normally you would use a 'V' bit), and you can cut it
in all different sizes using the proportion feature in the [FP] Command. Note that the
underline portion of the logo cuts first, followed by the letters. The file ends with a
couple of 3D moves to carve the shape of the flying wood chips in our logo.
Mount the X-Axis Proximity Switch Targets and Check The Y-Axis
Proximity Switch
With your tool powered up and moving, we can finish up getting the Proximity Switches set
up.
• Now (assuming you have the End Stops in position to keep the car from coming off
the rails) move the car to about 2” from the end of the X track (you’ll do both ends,
so start at either). This is about where we want the limit switches to trigger.
• In the prox switch kit there are (2) 1/4”-20 bolts, (2) ¼” flat washers, (2) ¼” nuts,
and (2) 1/4” T nuts. Place the nut on the bolt, the flat washer, followed by the T nut.
Remove the black end caps from the table side and slide the target into the second
slot from the bottom, of the table side extrusion. The target should capture the table
side between the T nut and flat washer. Tighten the bolt until it begins to tighten into
the slot, back off slightly to allow movement side to side.
