Cut Calibrations

1. Backup the PMAC.
2. Disable both print modules in the plate marking control panel.
3. Make sure the Waste to Infeed feature is enabled on the toolbar.
4. In Simple, open the job file named "calibration_35mm.smp2" (or "calibration_45mm.smp2" for New-Zealand) located in C:\Simple\Documentation\Commission Files\.

Note: do not forget to create another backup of the PMAC once all the required cut calibrations are complete.

1. Feed a straight 6‑m-long timber into the saw.

2. Cut the 50‑mm-long block named "A1" (select it and click  on the toolbar).

   1. The initial dock cut should remove between 3 and 5 mm from the leading end of the timber. If the dock cut misses the timber or is too short, open the Setup window and increase P513 to cut further into the timber. If it is too long, decrease P513.
   2. Adjust P509 until the block is exactly 50 mm. (Increase to lengthen the block or decrease to shorten it.)

3. Cut the member named "B1".

   Note: double-click the length field on the member diagram and set it to 50 mm shorter than the remaining timber length.

4. Adjust both P721 and P722 until the member is exactly the desired length. To do so, measure the difference between the actual cut length and the desired length, then divide the difference (in mm) by the desired length (in metres) and add the result to both variables to lengthen the member (or subtract it to shorten the member).

   EXAMPLE 

   If a 5.95‑m length is short by 3 mm, you need to increase both variables by 3 / 5.95 = 0.50.

5. Make a note of the original value of P610 then set it to any value less than 50 mm.
6. Feed the remaining timber into the saw and recut the 50‑mm-long block named "A1" (select it and click  then  on the toolbar).
7. Adjust P630 until the block is exactly 50 mm. To do so, measure the difference between the actual cut length and the desired length, then add half the difference (in mm) to P630 to lengthen the block (or subtract it to shorten the block).
8. Reset P610 to its original value.
9. Cut the 300‑mm-long wedge named "E1" for a front fenceline (or "F1" for a rear fenceline).

10. Adjust P514 until the wedge is 300 mm (±1 mm). To do so, measure the difference between the actual cut length and the desired length, then add a third of the difference (in mm) to P514 to shorten the wedge for a front fenceline / lengthen it for a rear fenceline (or subtract it to lengthen the wedge for a front fenceline / shorten it for a rear fenceline).

    EXAMPLE 

    If the wedge is 6 mm too long, you need to increase P514 by 6 / 3 = 2 for a front fenceline (or decrease it for a rear fenceline).

11. Cut the member named "H1" for a front fenceline (or "G1" for a rear fenceline).

    Note: double-click the length field on the member diagram and set it to 50 mm shorter than the remaining timber length.

12. Adjust P510 until the member is the desired length (±1 mm). To do so, measure the difference between the actual cut length and the desired length, then add a third of the difference (in mm) to P510 to shorten the member for a front fenceline / lengthen it for a rear fenceline (or subtract it to lengthen the member for a front fenceline / shorten it for a rear fenceline).

    Note: when repeating this cut, make sure the follower has a flat surface to press against (not a scarf cut), otherwise the length will be incorrect.

13. Square both ends of the remaining timber and feed it into the saw to cut the member named "DBL_BEVEL1".

    Note: double-click the length field on the member diagram and set it to 50 mm shorter than the remaining timber length.

14. Measure the height of the centreline from the bottom edge of the timber. It should be 17.5 mm for 35‑mm-thick timber (or 22.5 mm for 45‑mm-thick timber). Adjust P515 by the error (in mm) until the centreline is at the right height. (Increase to move the centreline up or decrease to move it down.)
15. Repeat the last two steps with the member named "DBL_BEVEL2" to adjust P511 this time.
16. Click  in the Setup window to permanently save the variables.

1. Make sure the following lines are added to the Simple.ini file located in C:\Simple\ :

   • Undercuts = 1
   • DynamicUndercuts = 1

2. Open the Setup window and adjust the following variables:

   • Set P574 (Undercut Enable) to "1".
   • Set P575 (Undercuts Z‑axis Adjustment) to "1".
   • Set P576 (Undercuts Y‑axis Distance) to "150" (starting point).
   • Set P577 (Undercuts Blade-to-C Adjustment) to "0".
   • Set P578 (Undercuts X‑axis Adjustment) to "0".
3. Set the cutting speed to 10%.
4. Feed a straight timber into the saw.
5. Cut the 100‑mm-long block named "UC1" with an undercut (select it and click  on the toolbar).

6. Watch the saw while the undercut is being made and make sure that:

   • no collisions occur between any part of the saw head (including cables and hydraulic hoses) and the timber.
   • the Z‑axis stopper does not touch the top of the Y‑axis assembly at any time.

7. Inspect the undercut and adjust the variables as follows:

   1. Adjust P575 and P576 until the undercut is along the entire width of the board and at least 2 mm deep at the shallowest point without causing any collisions between the saw head and the timber or between the Z‑axis stopper and the top of the Y‑axis assembly.

      Notes:Increase P575 to make the cut deeper or decrease it to make the cut shallower.Increase P576 to cut further into the width of the timber producing longer intermediary cuts or decrease it to produce shorter intermediary cuts.

   2. Adjust P577 by half the error until the two intermediary cuts line up.
   3. Adjust P578 by the whole error until the left edge of the undercut is at the correct location (60 mm from the left end of the member).
8. Click  in the Setup window to permanently save the variables.

1. Open the Setup window and set P632 to "0" to disable the overcuts.
2. Set the cutting speed to 20%.
3. Feed a straight timber into the saw.
4. Cut the 100‑mm-long member named "BM1" with birdsmouth cuts (select it and click  on the toolbar).

5. Watch the saw while the birdsmouth cuts are being made and make sure that no collisions occur.

   Note: stop the saw before the last end cut (do not allow the member to be severed from the stick).

6. If no collisions occurred, set the cutting speed back to 100%.

   Note: if collisions occurred, contact Vekta Automation for further assistance.

7. Pull the timber out and inspect the birdsmouth cuts. Refer to the corresponding diagram below and adjust accordingly.
8. Enable the Long Lead feature on the toolbar and feed the same timber into the saw.
9. Repeat the cut and readjust according to the diagrams below until you get a perfect apex on both sides. It needs to look like the first diagram before moving on.

Notes:All measurements and adjustments are in mm.While variable P711 can be adjusted in the Setup window, Q585 needs to be adjusted in the terminal window of PEWIN32PRO.

1. On the last perfect apex cut produced, measure the position of both apex points from their respective side (A or B) and from the leading end of the timber. They should be at 25 mm from their respective side and at 50 mm from the leading end. Adjust variables P712 and P714 to correct their distance from the leading end, as well as variables P713 and P715 to correct their distance from the sides.
2. Make sure P636 is set to "1.05" and P635 is set to "6" for 35‑mm-thick timber (or "7" for 45‑mm-thick timber).
3. In the Setup window, set P632 to "1" to enable the overcuts.
4. Set the cutting speed to 20%.
5. Feed the timber into the saw and recut the 100‑mm-long member named "BM1" (select it and click  then  on the toolbar).

6. Watch the saw while the overcuts are being made and make sure the cutting depth is such that the centreline of the blade is below the bottom of the timber. If not, adjust P633 until it is.

   Note: stop the saw before the last end cut (do not allow the member to be severed from the stick).

7. If no collisions occurred, set the cutting speed back to 100%.

   Note: if collisions occurred, contact Vekta Automation for further assistance.

8. Pull the timber out and inspect the birdsmouth cuts. Refer to the corresponding diagram below and adjust accordingly.
9. Click  in the Setup window to permanently save the variables.
