Today I get to test the tool change making sure it works. First of all, I have to determine what to align first. Align magazine with s-arm or spindle with s-arm. In order to determine which is which, you'll have to see how s-arm is bolted on to. If it is bolted onto the spindle side, then you align with magazine first, and if it's bolted on the magazine side then you align with the spindle first.
Once you have aligned the s-arm with the correct one, then you put down the test ring and use a scale to feel if the spindle is aligned correctly with the s-arm, and you also measure the distance from the face of the test ring to the face of the spindle by using caliper. Typing M991 All axis interlock off to align the spindle to the s-arm.
Next, you will put a real tool inside the tool pocket and run a M907 s-arm jogging mode to see how the tool fits into the spindle, once it's in you use the caliper to measure the distance again, it should be only couple decimal micron-meter off.
Also, I get to do the coolant modification today. Basically TME uses external coolant tank instead of the stock coolant tank that comes with the machine. Hence, I have to remove the solenoid valve and make it so it's independent from the machine. The concept is fairly simple, however, the hardest part of this task is that it takes a lot of energy to take off the hoses, nuts, that connected to the solenoid.
