Z axis will not go down
« on: February 09, 2010, 11:09:02 AM »
Hi all I hope some one can help me with this..

when tuning I get a smoot run on my Z motor, up and down.

when joging I get a smoot run on my Z motor, up and down.

But when I try to run some code my Z motor will not go down
it just "humming".

It means that Z is humming and X and Y then run, then Z goes up, X and Y run Z humming and so on.
So Z is getting heiger and heiger up.

Hope you understand what I mean

Start by halving the velocity and doubling the acceleration time figures in the z axis motor tuning.

You may have tuned the motor with the jogging set at 50%
