Morgan Rushworth Machines with Elgo P9521 Control. With no datum switch.

 

  1. Send back gauge to 50mm and make a cut and measure it. I.E. 49.32.
  2. Take 49.32mm from 50.00mm = 0.68mm.
  3. As the machine will not allow a fine adjustment the step below must be made.
  4. Send Back gauge to 50.7mm and make a cut and measure, it should now measure 50.0mm.
  5. Press and hold F for 4 seconds and type in 98 and press > then enter 250565 and press > again, type in 07 and press > again this brings up parameter no 07, change the figure to 100.0mm and press F, the top figure will change to 100.0mm
  6. Press and hold F for 4 seconds press > type in 07 and press > again this brings up parameter no 07, and enter 50.0mm then press f and the top figure will change to 50.0mm you are now datumed.
  7. If the figure is out of calibration by a large amount, direct entry of the correct figure is possible. Simply enter the correct figure in step 5 and the machine will be datumed.
  8. To lock parameters just turn the power off and back on.
