workpiece.

Vacuum Table Troubleshooting.

The vacuum table does not grip the Microrouter floor:

• Ensure the floor is clean and free from any dust or debris.

• Check the vacuum pump is functioning correctly, the hoses are not blocked or broken

and the exhaust vents are not blocked or covered.

• Check the condition of the vacuum table lower surface rubber gasket.

The vacuum table will not hold the workpiece:

• Check the workpiece covers as many cells as possible.

• Check your workpiece is flat. The vacuum table will not hold rough sawn timber or

materials which are seriously cupped or twisted.

• Check that the workpiece is not porous.

• The created vacuum is too weak. Check the performance of the vacuum pump.

3) Place the workpiece onto the upper surface of the vacuum table,

to cover as many complete cells as possible. Push the

workpiece down to open the ball valves in each of the covered

cells, engaging the vacuum.

4) The vacuum suction will hold the workpiece securely on the

vacuum table. Push the side of the workpiece to see if it is held

firmly. Do not lift the workpiece, since this will break the vacuum

seal. Once the machining operation has been completed, switch

off the (running) vacuum pump by lifting the cover and pressing

the square, green, button once. This will release both the

workpiece and the vacuum table.

Note that a safety feature prevents the pump from being switched

off when either the spindle is rotating or the CNC control software

is operating in Auto mode (ie, automatically running the loaded

CNC program). If you need to switch off the pump in these

circumstances, you must stop the spindle and or CNC program,

then switch the CNC control software to operate in Jog mode (ie,

manual control of the machine).
