The vertical alignment is extremely important! If the wire is not vertically aligned, the
workpiece will come out with undesirable taper due to the out of alignment condition.
We recommend that you use this procedure often to test for vertical alignment.
NOTE: Before starting this procedure, be sure that the upper guide, table and the test
block are completely dry. If necessary remove the flushing hose and blow air through the
upper head assembly. Using a hard Arkansas stone, de-burr the test block and the table.
The table is stainless steel and nicks and scratches can form. Set wire speed to 2 and
tension to what will be used when you skim cut. Also set dry run to 0
1) Go to the “MAL”,”MDI” screen, type G91 and press “ENTER”.
2) Place the test block (that came with the machine) on the front table as straight as
possible and make sure it is down good by sliding it a bit.
3) Type C777 and press “ENTER”. (C777 is a very weak condition that will let you see
the sparks between the wire and the test block ).
To adjust the “U ” direction:
4) Using the X and Y jog keys, position the wire close to the right of the test block and
jog Z-axis about .500" above the test block.
5) Type G1X-1.5 and press “ENTER”. The wire run will activate and begin moving the
to the left (toward the test block).
6) When the wire approaches the workpiece, you should see the sparks. If you don’t,
there is still water on the areas that should be dry.
Use the U+ and U- keys to form a uniform spark from the top of the test block
to the bottom. Note the blue “U/V key on the keyboard. You will have to hold
it while pressing the U+ or U- keys.
7) Move the test block away from the wire (by hand) and confirm the spark
again.
8) When satisfied, press the “OFF” and “ACK” key
To adjust the “V” direction
10) Reposition the squaring block onto the left or right table.
11) Jog X and Y to position the wire below the squaring block.
12) Type G1Y1.5 and press enter (the wire will activate and begin moving up ).
13) When the wire approaches the block and begins to spark, adjust the V axis by using
the V+ or V- jog keys to make the spark uniform from the top of the block to the bottom.
14) Move the test block away from the wire, and confirm the spark again.
15) When satisfied, press the “OFF” and “ACK” key.
16) Type G90 to go to absolute mode.
17) Type G97UV and press “ENTER” to zero out the U and V readout in all screens.
