It is important that the parallelism of the GY axis to the backfence is set and maintained along the length of the rack. This tutorial describes how to check this parallelism without the need for measuring equipment
Potential Symptoms of a problem
Use the laptop to enable you to control the Service screen whilst inside the infeed table
Ther gripper setting jig is used to give an accurate and reliable zero to locate the gripper jaw to. Any piece of aluminium reinforcing box section will also work Create a spreadsheet or a table to log your results,.
If the backfence to gripper is different in this location, it will be visible by a gap or interference to the jig
Move GY axis (in 0.25mm increments) to make it touch
Log GX value vs the GY value in your table / spreadsheet
There may be areas where the offset changes more than others - these deserve more detailed inspection with closer GX axis increments
PASS
The error should be within +/- 1mm along the rack
In the given example of measurements, the overall range was 0 to +1.5mm
Therefor the GY axis datum should be adjusted by+0.75mm so the error range will then be -0.75mm to +0.75mm(within tolerance
FAIL
If the error variance is outside this range, the backfence will need to be rest to correct this
