1. Check the X Probe mechanics: Loose nuts, bolts, springs, & bearings on X Probe assembly. Check the encoder gear, gear rack, xprobe drive assembly, xprobe stop, etc.

2. Check the alignment of 1/2"x6" flat bar and encoder gear and rack. X Probe should run down entire length of outfeed smoothly. If there are any spots where the X Probe bounces or binds, the probe tip moves up/down from the rolls or in/out from the chain guard, that area needs to be fixed.

3. Check the encoder, encoder cable, connector, shield & wire connections in console.

4. Set the gear rack. Start at the stop (near machine) and loosen the 1/4"-20 bolts on every piece of gear rack. Remove the very last piece and use it to mesh the first two pieces together. Use a welding clamp to hold the meshed gear racks tightly. Make sure there is clearance between the two pieces of gear rack (See below). Tighten the bolts. Start from the meshed joint and work to the opposite ends of both pieces. Then mesh the second piece of gear rack (already tightened) to the third piece and tighten bolts on third piece of gear rack (from meshed end to opposite end). Continue all the way down the measuring system.

5. Program a mark on the web of a beam 3" from the end. If mark is not correct, adjust the stop, and run again with a different gauge until correct.

6. Program a mark on the web of a beam every 1’. If marks are not correct, determine exactly where they start to become inaccurate.

Example: Correct until 15’ and then long 1/16" after.

Position the material in the machine (web punch) where the marks start to become inaccurate. Move the X Probe to the material to find the area of measuring that is inaccurate. There should be some mechanical reason for the inaccuracy.
