Roland MODELA PRO II series Use and care manual

Advanced Calibration
The purpose of this document is to assist users of the Roland MDX-540
fine tune the accuracy of their machine when using the 4th-axis option
(ZCL-540) – The following steps will assist users who observe any shifts
or offsets when performing double sided milling. We will cover two
sections:
•Section 1 - Setting Origins
•Section 2 – Manual Adjustments

Section 1
•Make sure to have your ZCL-540 user manualhandy.
•Begin the Y-origin sensor detection process. (pg 43-46)
oConnect the sensor cable to the Z-origin sensor. (pg 43)
oInstall Y-origin sensor bar. (pg 44)

oBegin the “Detect Center of Rotation” process. (pg 45-46)
•Set your Y and Z origins at the center of the A axis. (pg 47-49)
oOpen Base Point settings and use the “Set ___ at center of
rotation” drop down menu to set the Y-origin. (pg 47)

oConnect the sensor cable to the Z-origin sensor and install a
tool. (pg 48)
oOpen Base Point settings and use the “Set ___ at center of
rotation” drop down menu to set the Z-origin. (pg 49)

•Set your X and A axis origins. (pg 50- 51)
oMove your tool to the right of your work piece along the X-
axis and set your X-origin using the “Set ___ here” drop down
menu. (pg 50)
oMove you’re Axis to a zero degree position and use the “Set
___ here” drop down menu to set the A-origin. (pg 51)

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. (pg 53)

•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)
•Check your part in the Z direction for any similar adjustment
values. (pg 53)

•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. If you continue to have issues
return to Section 2 and repeat the calibration process. You can

file (ZCL-540_Calibration_Cube) to help with this process.
