Your're right Darek, thanks for the work.
Servo machine? I'm not sure, is this the type of motor Darek, how could I tell?

Yup, that pictures better, does look like backlash...

Ther are two types of motors you can have, servos or steppers, servos will  have encoders on them and steppers usually dont.
 What kind of machine do you have and do you have a link to a web page for it?

It's a home built beauty, not by me, by two others, one who made the structure, and put some controls on, and one who took the wiring out again and reworked it. I'll post some pics tomorrow if I can, and see what you think.
The guy I got it off said this forum was great, and very helpful, and he was right.

Thanks guys..
Jim

Are the motors square in section? if so they will be steppers. If they are round then they could still be steppers but may also be servos.

Not always ;)  I've got some square servo's!     

Steppers will generally have 4, 6 or 8 wires.   Servo's 2 for dc and 3 for brushless + the encoder cables.

It's great to have you guys on my case. They're definitely round, but I'll have to count the cables in the morning.

'night all.

I think if you can post a pic of the inside of the control box we can tell you what you are running :) The guys here have installed and run about everything ;)

True..  The drives will tell the whole story.   But as others have mentioned this looks like classic mechanical backlash on the x axis screw.

Are they ballscrews or standard acme I wonder.
