The Sodick control allows you to move any axis (one or more) by “MDI” in a similar
way to how it is done in a program. Any rules you know related to programming will still
apply to
“MDI” axis motion (G54-G959, G00, G01, G02, G03, G90, G91, etc.)
1) Go to the “MAL”,”MDI” screen .
2) If you intend to actually cut something during this motion, type “C” and the
condition number you wish to use (example: C411)and press “ENTER”.
3) Type the mode of motion you wish (G90 or G91) and press “ENTER”.
4) Type the kind of motion you wish to make (G00 for rapid or G01 for straight line
cutting). Note: the G01 will automatically activate electricity to the wire, turn on
the wire run and flushing. Also, the current condition will be in effect for cutting.
5) Type the axis and motion you wish to make (example: G00 X1.5).
6) Press “ENTER” (motion takes place).
Notes:
a) Machine assumes plus (+) unless minus (-) is input for axis motion.
b) In incremental mode (G91), movement is taken from current position.
c) In absolute mode (G90), movement is taken from program zero and assumes a
previous G92 setting of the axis displays was done.
Use G00 for non-cutting movements and G01 for cutting movements.

There are several procedures used to install a spool of wire, based on the machine model.
All machines require that you manually feed the wire all the way through the machine
until it reaches the pinch rollers just above the wire bin. No matter what style of machine
your company owns, there are some common notes that will apply to installing the wire.
NOTES ABOUT INSTALLING WIRE:
1) After you remove the wrapping from a new spool of wire mount it onto the spool shaft.
Check that the wire unspools smoothly by manually pulling several yards of wire off the
new spool. After the wire is wrapped around the rubber wire tension roller and the plastic
rollers, it is wise to check that the wire is “pointed”. If there is any burr on the wire, you
will not be able to pass it through the AWT unit or the upper and lower wire guides. One
very common technique to “point” the wire is to pull the wire apart after heating it with a
lighter. As the wire is pulled apart, it forms a perfect sharp point that will pass easily
