Whether using the jog shule or the keyboard arrow keys, 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).
Step Mode – 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).
Connuous Mode – In Connuous mode the mill jogs at a connuous velocity when you press and
hold any one keyboard arrow 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.
Feed Rate DRO – Feed rate is the velocity at which the workpiece can be fed against the machine
tool. The DRO, or digital read out, is the eld that displays this velocity.
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 buon indicates acve
step size.
Spindle Controls – The REV, Stop, and FWD buons can be used to manually control the spindle
(see Figure 6.8). Rev is the equivalent of typing M04 in the MDI Line – it starts the spindle counter
clockwise at the RPM specied in the Spindle RPM DRO (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. Pressing REV or 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.
