Typically this process should be done after squaring the machine. If the machine has ever been knocked out of square, then it can cause tool change location issues.This document can be used as a bandaid fix to resolve tool locations so that the machine can be operated.
Begin by powering on the machine and homing it.
Next, typically a v-bit or v-groove bit is recommended to be installed in the spindle. An endmill can be used as well.
Go to the F1-Setup page and input password HTG for machine models 2020 to 2023 or GTH for 2024 and newer.
Double Click to Tool Changer > Linear Type 2 > and identify the tool locations and z height > Take a picture.
Close those windows, and go to F3 Jog page.
Then move your spindle so that it is above your tool rack.
Start with location 1, where you bring the tool down very close to the pull stud and centre it so that X and Y and perfectly above the tool holder in the fork.
Look at your F3 Jog page. Locate the MACHINE coordinates on the right side.
DO NOT use your work origin coordinates or you will crash the machine.
Write those down for Tool location 1. Then move on to Tool 2 and repeat the same check. Document each location accordingly.
Once all 8 or more are complete, update the values in your Tool Changer page on F1-SETUP.
Next you will have to check the Z height. The process is similar. Remove the tool from the fork. Carefully bring the spindle down in place and level off the height.
Once you're happy with the height. Double check this height matches across a few different forks. Take the average.
Only one Z value can be used for the entire rack. Take your new value and input it in the Z pick and place location.
Now carefully test your tool changes. Hold the e-stop for any errors. Watch out for tools crashing into other tools if the slots are setup incorrectly.
