Hi All:
I’m new to all this, but I have a problem with my new IH. Got it all put together and started moving the axis, tuning the motors and all, things were going good, but I soon discovered my limit switches were not working, after playing around for awhile I got the X --and X home to work. Next I disconnected all but the X axis limit inputs to my LTP1 port and turned on the power. The Z axis started to move down all on its own, not real fast, and not smooth, I had to hit the E stop. So I reconnected everything like I had it, turned on power, same thing chug chug chug moving down. If I disconnect the motor leads to the Gecko that controls the Z axis I can move the X and Y around just fine, real smooth and fast. Limits still do not work, but every time I put power to Z motor down it goes.
