It's alive! Well.......almost

[thomashomer1986]

Hi there thanks for the reply.

I have just tried swapping the z stepper cables with the y and the z axis moved fine, the y then had the problem. So does this tell me that the wiring is fine but there must be something wrong with the mx3660 unit?

I hope that's not the case! As I bought this over a year ago which means my warranty will have run out! Even though it is basically brand new.

Can you post the .ini and hal files and a picture of the settings on the drive like I suggested before.

[thomashomer1986]

Apologies for missing your previous question.

i cannot upload the .hal and .ini files, so I'm presuming you just mean copy and paste the content?

One thing I have just noticed is that when im in the step config wizard and i click on the 'test this axis' button. my z axis moves fine?

[Clive S]

Ok Just had a quick look see this:-
TYPE = LINEAR
HOME = 0.0
MAX_VELOCITY = 25.0
MAX_ACCELERATION = 25.0 this should be a lot higher
STEPGEN_MAXACCEL = 31.25
SCALE = 800.0
FERROR = 1
MIN_FERROR = .25
MIN_LIMIT = -0.001
MAX_LIMIT = 0.001
HOME_OFFSET = 0.0

so the most it can move is .002mm So alter the Min limit and try again say -100 or what ever your Z is
