We will cover two sections: •...
- Page 2 Section 1 • Make sure to have your ZCL-540 user manual handy. • Begin the Y-origin sensor detection process. (pg 43-46) o Connect the sensor cable to the Z-origin sensor. (pg 43) o Install Y-origin sensor bar. (pg 44)

- Page 6 Section 2 • Once you have milled out your part using double index milling, check the “seam” of the part to find any adjustment values. (pg 53) • Observe what direction this shift occurs to determine what type of adjustment value you will use. For example, if the “top” of the part looks like it shifted upwards the Y direction, then your adjustment value will be negative.
- Page 7 • Divide your adjustment value by two and use “Set Base Point” in VPanel to correct your Y origin position. For example, if you had a measured adjustment value of 2mm then you would change the location of your Y origin by 1mm only. (pg 53) •...
- Page 8 • Divide your Z adjustment value by two and use “Set Base Point” in VPanel to correct your Z origin position. Again, if you measure an offset of 2mm, your adjustment will be 1mm. (pg 53) • Re-cut your part under these new origin settings to double check that your adjustments were correct.
