3. Run the program and notice if the motor loses steps. If so, increase the
Direction Change Delay. Otherwise decrease the number.
4. Repeat the above process until you reach a reasonable delay time that
eliminates any motor slippage. Note that this number is typically between
0.05 and 0.3 seconds. If you do not see any slippage at a delay of 0
seconds, it is recommended you enter at least 0.05 seconds.
5. Repeat the above process for all axes.
4 To Set the Jog Rates
1. Choose Feedrate/Ramping from the Setup Menu.
2. Fill in both the Slow Jog Rate and the Fast Jog Rate text boxes. Choose a
Slow Jog Rate that will allow fine positioning of the machine tool
(typically about 2-5 in/min). Choose a Fast Jog Rate that will move the
tool quickly, yet allow you to remain in complete control without creating
a dangerous situation. Remember that the CNC machine cannot jog any
faster than the maximum feedrate for each axis.
4 To Set the Maximum Arc Feedrate
Due to the computations involved during circular interpolations, an arc cannot
be executed as fast as a line. For this reason, there is a user-settable limitation
for the maximum arc feedrate.
3. Write a G-Code program that cuts a circle at the maximum feedrate. For
example, if the maximum feedrate were 25:
G00 X2 Y2
G02 X2 Y2 I1 J1 F25
4. Run the program and notice if either the X or Y motors lose steps. If so,
decrease the feedrate in the program.
5. Repeat the above process until neither motor loses any steps. When you
are done, enter the final feedrate from the program into the Maximum Arc
Feedrate text box. If there was no loss of steps when the Maximum
Feedrate was used, enter the Maximum Feedrate into the text box.
Setting Machine Zero
Setting Machine Zero using home switches not only sets up the machine tool
envelope, but also allows you to re-position a tool to a precise physical location
even after the controller has been turned off or has lost power.
Setting Machine Zero without home switches won’t help you reposition a tool
after losing power, but it will set the machine tool envelope. This is very useful
because the software will always ramp down the machine to a complete stop at
the defined limits of the machine tool envelope.
