Step and Connuous Jogging – Whether using the jog shule or the keyboard, there are two modes
of jogging: connuous and step. When using the keyboard to jog, switch between modes using the
Jog Cont/Step buon (see Figure 6.7).
In Step mode, the mill jogs in steps, where the step size is controlled by the four buons to the right
of the Step label (see Figure 6.7).
In Connuous mode, the mill jogs at a connuous velocity when you press and hold any available
keyboard key; stop the mill by releasing the key. Axis moon is key-specic as shown in Figure 6.6.
The velocity is set using the Jog Speed Slider (see Figure 6.7). To set jogging velocity to the maximum
speed, click and drag the Jog Speed Slider to the far right posion.
Noce that in imperial units (type G20 in the MDI line), the step sizes range from 0.0001” to 0.1”
(see Figure 6.7), whereas in metric mode (type G21 in the MDI line) the step sizes range from
.01 mm to 10 mm. The illuminated LED in the upper right corner of each Step Size Buon indicates
acve step size (see Figure 6.7).
Feedrate DRO – Feedrate is the velocity at which the workpiece can be fed against the machine tool.
The DRO is the eld that displays this velocity.
Spindle Controls – Stop and FWD can be used to manually control the spindle (see Figure 6.8).
The Stop buon stops the spindle, similar to the M5 command. The FWD buon starts the spindle
clockwise at the set RPM.
These buons are unavailable when running a G-code program or in the middle of an MDI move.
Clicking FWD triggers an alarm if the commanded spindle speed is outside of the valid spindle speed
range for the mill's current belt posion.
