Hey everyone, I had the toolchanger working well (note...had) and it failed halfway through the kraken print. It turns out now my toolchanger can pick up a tool but wont put it down. It goes through the motions of putting the head back and turning the tbar but when it backs up the toolhead is still partially attached and this lead to some crashes. I have tracked it back to the t-bar doesn't reset back to perfectly parallel with the bed. I also found that the tbar can manually be turned by hand with the motor enabled by a few mm. I confirmed this by taking the back cover off and exposing the gears aren't moving, but the screw holding the t-bar to the gear is slipping. Is this normal behavior or did I find the root cause? Any ideas how to keep it from sliding? I have some star lock, m3 lock washer coming to try to keep the bar from slipping.
