i am trying to tune in my z axis on my IH CNC kit. right now i seem to get a loud shrieking noise when the axis tries to move. i've been playing with the gecko adjustments and nothing seems to be getting me any closer to a nice hum. the x and y axis move very nicely and the servos hum just a little.
one thing i did notice though on my x and y axis, is that the belt tends to walk on the pulley some. i don't know if this is common with the kits or not, but i followed the instructions that were supplied to the letter.
thanks for the help
