|Setting Machine Motion Speeds|
Entering Control-D at the command prompt will cause the Movement Parameters dialog window to be presented. This is a quick way of setting machine motion speeds.
This is also the same dialog window that will be presented when a machine move is interrupted by hitting any key on the keyboard. When machine movement is interrupted the type of movement will be indicated at the top of the active column. It will be either Rapid or Cutting, flashing with yellow to red background.
There are four different motion speeds predefined by SuperCam.
1. Travel speed is used when the machine is moving between cuts.
2. Cutting speed is used when the machine is thought to be cutting material.
3. Spindle Travel speed is when the spindle is moving up or down but is not engaging material to be cut.
4. Spindle Cutting speed is when the spindle is moving through material and cutting. This is when it is at the surface of the material or below it and it is moving down.
For each speed there are three parameters, Speed, Slew and Ramp.
Speed parameter is the first parameter in the list. It is the speed that the machine will start moving at.
Slew parameter is the second parameter in the list. It is the rate of speed that the machine will accelerate to at the start of the movement and decelerate from at the end of each movement.
Ramp parameter is the rate of acceleration and deceleration. This value is added or subtracted from the current instantaneous speed of the machine at the end of each Ramp Period. The ramp period is normally 0.010 seconds. When the Ramp parameter is very small the machine will take a long time to achieve the slew speed. When the Ramp parameter is increased the time required to reach slew speed is decreased.
