Determine the model number for your Shark machine.

    Model numbers are used with the CNC Shark series to set the motor steps per inch values and can be different between the various CNC Shark releases. If you have recently upgraded to the HD Controller and Pendant or upgraded to the HD5 Gantry, you may need to update your model number. 

    If your CNC Machine is not listed on this quick reference chart, please see the steps below for testing and determining your CNC machine's model number. 

CNC Machine	Model Number
Shark II Shark HD5 Shark HD500 Shark HD510 Shark HD520 Shark HD5 Gantry Upgrade	4003
HD4 HD4 Extended bed Shark II	4004

CNC Machine	Model Number
SD100	300
SD101	400
SD110	102
SD120	202
Piranha FX	100
Piranha XL	200

Test the axis Travel. (Pendant)

1. Make a pen mark on the spoilboard.
   1. If there is no spoilboard clamp a piece of material that is 6”x6” or larger to the deck of the machine.
2. Move and lower the router bit to the mark on the material surface.
   1. Select the Zero XYZ button on the LCD Pendant.
   2. Press OK to accept the change.
3. Tap the 0.000 number readout above the Z+/- buttons.
   1. A number pad will come up.
4. Enter the number 2 (for HD machines) / 1 (for SD machines), then select the red Move button.
   1. The Z-axis will raise what the machine thinks is two inches or one inch.
5. Measure the physical distance between the material surface and the tip of the router bit.
   1. Note the distance for Z.
6. Repeat steps 3 through 5 for the X and then Y axes.
   1. Note the distance for X.
   2. Note the distance for Y.
7. See the chart below for the correct Model number.

Distance traveled when jogged 2 inches for HD machines.
X-axis	2"	2"	1"
Y-axis	2"	2"	1"
Z-axis	2"	4"	2"
Model number	4003	4004	4001

Distance traveled when jogged 1 inch for SD / Piranha machines.

X-axis	1"	1"	1"	1"	1"	1"
Y-axis	1"	1"	*1"	*1"	*1"	*1"
Z-axis	1"	1"	1"	1"	1"	1"
Model number	300	400	*102	*202	*100	*200

* IMPORTANT NOTE: The difference between model numbers 100 / 200, and 102 / 202 is the direction of travel of the Y-axis.
