4.1 Setup C Axis
****ATTENTION! Ensure that no magnetic tools go near or touch the magnetic scale of the measuring system which is built into the linear bottom rail. This will destroy the measuring system!****
C axis alignment test
Use the hand entry function of the machine to make a cut plan that resembles the following shape. If you need to learn how to make a cut plan see video How to Create a Cut Plan using Hegla Cut. The shape is a series of 1-inch wide strips in two directions. The length of the strips is not significant, but usually about 24 inches. It should not include edge deletion. The glass should be no thicker than 6 mm. Your place should look similar to the plan below.
After the machine finishes the cut, examine the shapes. If all the strips have a width of 1 inch then the C axis is OK. If the strips width alternate between more than and inch in width and less than an inch in width then the C axis may need to be adjusted. You may also have something bent within the cutting head (I.E. Pillar post, cutting head shaft, insert that holds pillar post to shaft).
C axis Adjustment
The best way to adjust the C axis is mechanically. First we need to determine the direction and amount of error in the C axis. To make more accurate observation, we need to temporally slow the Rapidline speed. This is accomplished by navigating the Rapidlines HMI to the Diagnostics screen by following the steps below:
- Log into the Service login from the Operator HMI: Service (Shift+F3), Service Hegla (Shift+F1)
- There is no password, just click the green check mark. If it asks for a password enter the password "STDMMI"
- You may have to click anywhere on the screen, before pressing F12 to go to the Diagnostic screen
- You can increase the machine speed with Shift+F6 for "Override +"
- You can decrease the machine speed with Shift+F7 for "Override -"
- You can click and drag with the mouse on either of the override buttons to change the speed.
Once there decrease the machine speed to about 30%. Next you must enter a cut plan that causes the machine to make long straight scores. Once the machine starts the cut plan observe the orientation of the cutting wheel holder. It should be pointing in the direction of the cut. If it is not, you will need to follow the steps explained below.
4.1.1 Position the cutting head on the cutting head change position
Use a 5.5 mm ring spanner to remove the spring.

4.1.2 Fit Cutting head linear tool and secure in position
Use a feeler gauge to fix the tool in position (approx. 1.0 – 1.1 mm). Adjust the air pressure so that the cutting head is in a floating position.

4.1.3 Mount dial gauge and adjust C axis
Mount the dial gauge on a Linear bearing ON THE TOP RAIL in a position where you can run it along the tool.
ATTENTION ensure that no magnetic tools go near or touch the magnetic scale of the measuring system which is built into the bottom rail.
Push the linear bearing back and forward and read off the dial gauge. Adjust the position of the C axis in the HMI (Service->F9->F2“Manual Travel“->F4,Target Point Travel“) until the dial gauge reads next to zero tolerance. Go into the MK_GRUNDOFFSET and add or subtract the difference from the original 90° position to the value for the C axis.
4.1.4 Bolt setup (cutting head turning point)
Remove the linear tool and set the air pressure back to normal setting. Mount the dial gauge so it measures the side of the bolt. Move the linear bearing back and forward until you find the highest point on the bolt.
Use the HMI to turn the C axis 180° and find the highest point again.
4.1.5 Setting the eccentric offset
The difference between the two highest points must be set so that the head turns on the spot. Use a 4mm Allen key to slightly loosen the clamp screw on the top of the cutting head. Attention ensure that the piston does not slip down when loose!
Use an 8 mm spanner to turn the eccentric bolt half the distance measured between measurement 1 & 2. Measure the two high points again and repeat the process if necessary until the difference between the two measurements is less than 0.01 mm. Tighten the clamp screw up and replace the spring.
4.1.6 Replacing and setup of the spring
The spring must be mounted so that a 6/10 mm feeler gauge fits between spring and mount.
