General Mach Discussion / Re: losing steps on z-axis (help)

Is everything clean in the Z platform/carriage? Does the ballscrew spin easily by hand (or have you checked?). I just discovered a similar problem in my mchine (and my bad technique for gib adjustment) however you appear to have linear slides so I have no idea if tension is adjustable simialr to gibs.

Simple answer is YES all is good in that aspect.

Will post my XML when I get back home along with everything I have about my setup. Thanks

A bit higher - The bit is no longer even touching the wood it was cutting to begin with.

Been playing with the velocity settings like you suggested and still no fix....

It is really odd - The z axis is always a bit higher at the end of the job than where it started. Where it thinks zero is changed almost every time.

Hi and I would greatly appreciate some help figure out why I lose steps or that is what I think is going on with my machine.....
I have this setup
https://www.finelineautomation.com/store/show/FLA100-00

with these electronics
https://www.finelineautomation.com/store/show/EL-0007

on X & Y I have 5 start screws and on Z I have single start screw.
during a job at some point the Z thinks zero is higher than it originally starts at. X & Y are perfect.

Thanks -
Keith

I feel like an idiot at the moment. Seems like something I should already know but am unsure.
If I slow down my acceleration rates for my machine, do I need to change the # of steps at all?

Hood -
How do I know when to adjust acceleration vice velocity?

Hi there -

I have my machine set and on most part everything runs pretty well but I sometimes lose steps on X-axis.
Q. If I slow down my acceleration, do I need to change any other settings or will everything else be ok?

Thanks
Keith
