Question #: 13700

Question: What is each axis' resolution for the blueChick in mm or µm?

Current Solution

The resolution for any of our machines is based on the driver microsetting setting and the machanical parts used for each axis.

For example:
The blueChick uses 9 tooth drive sprockets for the x and y axes.
To determine resolution use this formula:
Resolution = steps / inch or the travel in steps for one revolution of the drive sprocket
Steps = (motor steps) * (driver microsteps) or natural motor steps * microstepping setting on the driver
Inches = t(ooth coun)t *( tooth pitch) or the number of teeth for the drive sprocket

Resolution = ((motor steps) * (microsteps)) / (teeth * pitch)
In this example, the microsteps is 16 and the pitch is .25 inches
= (200 * 16) / (9 * .25")
= 3200 / 2.25"
= 1422.222 steps per inch

For the z axis of the blueChick, the resolution is typically based on 4 micro steps and the travel for one turn of the motor is 1/2". Therefore:
Resolution = (200 * 4) / .5"
= 800 / .5"
= 1600 steps per inch

  • WHAT IS D.O.F OR DEPTH OF FIELD FOR THE BLACKTOOTH LASER AND LENS?

    Depth of Field. This is how far the focal point goes before re-expanding again. With a 2" lens, you have approximately 2-3mm of DOF. This means that you'll have 2-3mm of perfectly focused laser before it starts to re-expand again. If you have a 4" lens, you will have up to 7mm of DOF.

  • wHAT IS THE SMALLEST LENGTH SHAFT I CAN USE FOR YOUR #25 DRIVE SPROCET?

    The hub length of the drive sprocket and the other mechanical devise that is used to connect on the shaft will determine the length of the shaft needed for use with the drive sprocket.

    The hub lengths for our drive sprockets are 1/2". So if you are connecting the drive sprocket to a motor, your motor shaft will need to be at least 1/2" in length.

  • WHAT IS THE DIFFERENCE IN A 2.5 AXIS MACHINE?

    An axis is a direction of motion controlled by the CNC machine control. It can be linear (motion along a straight line) or circular (a rotary motion). The number of axes a machine has determines it's machining capabilities. A 2.5 axis machine really has three moving axes, but only two axes can move together (most machines sold today are full three axis machines). For machining centers, a three axis machine will have three linear axes. A four or five axis machine will have three linear axes as well as one or two rotary axes.

    Note that 2.5 versus 3 axis has yet another context. 2.5 axis machining requires that the machine have three axes, but only two axes must be moving simultaneously at any one time. (Simple operations, like drilling and most milling, fall into this category). On the other hand 3-axis machining requires that all three axes be moving at the same time (More complex operations, like the machining of sculptured surfaces required in molds and airfoils, fall into this category.)
