OPERATING THE MACHINE IN MANUAL MODE
All TURNADO and MILL TURN machines can be operated manually
with a simple change in the VFD codes. This will unlock the stepper
motors so that you can turn them by hand and allow you to control the
spindle speeds and direction from the VFD keypad.
1. Turn your CNC POWER and STEPPER MOTOR switches to the
OFF position.
2. On the VFD key pad, press PRG and the display will read P0.
3. Use the UP arrow to go to P0-02 and change it to 1.
4. Now press the UP arrow until you reach the next code you want to
change, and follow the same procedure for Po-03 and PO-11 and set
them according to the decal on the machine.
5. Press the PRG button twice to exit setup.
Your display should now be reading all zeros.
Press the RUN button and turn the small speed control knob and your
spindle should begin to turn. If it is going the wrong direction, press the
MF.K button.
You can now control the speed and direction of the spindles with the
speed knob and operate the carriages by hand.
When you are running in MACH3 mode, you can make yourself a speed
chart by asking the spindle to go 1000 rpm, and then recording the Hz
reading on the keypad.
THREADING TIPS FOR THE
SHOPMASTER
Following are some settings and tips to make threading easier on your TURNADO
machine.
1. STEPS PER INCH AND BACKLASH COMPENSATION.
Be sure you take the time to do these settings according to the file provided.
Because the distance between threads can be very small, any error, especially on the
Z axis can cause the threads to be wrong pitch or even wiped over by subsequent
passes. Once you have made the adjustments and your machine can repeat
accurately, be sure that backlash compensation is turned on while threading. Also
set your % of Max to about 50-70 to insure a smooth transition from backlash move
to the cutting move.
2. CONSTANT VELOCITY V EXACT STOP
Constant Velocity setting means that the axis moves at the same rate from the
beginning of the program line to the end. Exact Stop is used when you want to turn
up to a shoulder and the axis must stop exactly at that point each time. In the Exact
Stop mode, in order to be sure the axis can stop at a fixed point, the axis will begin
to decelerate before reaching the end. So while threading this would cause the pitch
to change as the axis slows down. Therefore, while threading, always set your
machine to Constant velocity so the axis feed remains the same for the entire cut.
These settings are found in CONFIG>GENERAL CONFIG.
