hello every one, after searching Many forums, i came to the conclusion that this
forum is the best one to get educated and get help.
My issue is my Z axis "I think"
i used this machine for around 8 years with no issues, i bought it second hand, but it worked great for many years
but lately it started acting up.
i am creating wind turbine blades, i was successful making 3 blades, but when it came to the forth blade, everything went crazy.
i am using the same pc, same files, same everything, but the issue happens anyway.
i issue is that the Z looses it consistency, it drops more than it supposed to and it lifts more than it should.
i dont get it why!? why me?!
i changed the files, with no success, so i am baffled, it starts ok but then it goes wako.
attached are 2 pics, one blades is great and the other shows the inconsistency.
I am Asking you to help please, i am stuck,
i hope you can help me.
thanks
