Hello,
I have been struggling with the T-Rex on my JP. Please note that I originally posted this problem on the JP thread, thought I had figured it out, but obviously not, so restarting as a new thread. The T-Rex had been working fine, then all of a sudden it would bite down on the ball late, after it starts to move up. The video at the link below shows what it is doing.
I thought the problem was the switch that tells when the T-Rex is down, triggering the bite. I replaced the switch - in the square in the picture, same problem. I tried some hacks - to bend the arm to the switch up to trigger it earlier, but it actually gets triggered too early, I think by the set screw for the mechanism. I tried to put a rubber on the knob that triggers the switch, in the circle in the picture, but no help.
I took apart the cover the T.Rex, and nothing looks broken or out of place. Any suggestions on what to look at next, what is causing the mouth to close late would be great - I am at a loss.
Thanks!
