5. Spindle Control
5.1 G-Code Spindle Control
The spindle is controlled through G-Code using the M-Codes M3 (Clockwise), M4 (Counterclockwise), and M5 (Off). To control the spindle speed in RPMs an S word is added.
For example, M3 S2000 would turn the spindle on in the clockwise direction at 2000 RPM.
5.2 Manual Spindle Control
To control the spindle separately from G-Code use the spindle control on the Machine screen. The [Spindle FWD] turns the spindle on clockwise and the [Spindle REV] turns the spindle on counterclockwise.
Figure 14 - Spindle Control
The following spindle settings are also shown on the Machine tab:
- G50 Speed Limit – the maximum RPM the spindle can move with the current G50 setting
- Range – Pulley number selected and speed range
5.3 Spindle Display
The current spindle settings are shown in the main Spindle Display.
Figure 5 Spindle Display
- S – Commanded Speed
- Speed OV – Spindle Override Percentage
- rpm or ccs – the spindle speed in the current mode
- Load – % of the load of the spindle. This also is shown in the horizontal gauge.
6. Machine Output Control
[Mist] turns on and off the Mist control (Figure 14).
[Coolant] turns on and off the Coolant control (Figure 14).
[Chuck] turns on and off the Chuck control (Figure 14).
[Tailstock Backwards] turns on and off the Tailstock control (Figure 14).
7. Fixture Offsets
All G-Code files have their own coordinate system. In order to allow parts to be located on the table at any desired location, the part offset can be defined to adjust the actual location of the part on the table.
Part offsets can be defined and saved using G54-G59P120. The functionality is designed to allow different tooling setups to have predefined zero points to allow for streamlined setup.
You can view the fixture table and change the values directly by clicking the [Show fixture Table] button. The values can also be set by using the MDI command to select the G-Code number for the fixture offsets to be stored in. Once the machine is at the desired zero position, zero Z by pressing the [Zero Z] button.
