Topic: Z-Axis issue

My bed is unlevel dipping forward, the auto-leveling compensates for this by moving the bed up and down as the print head travels along the Y-Axis.  The Z-Axis raises smoothly but does not lower smoothly, it has a skip or judder as it lowers.  This only seems to happen for the first 5 or 6 layers then it smooths out.

I'm thinking there might be an issue with the z-axis screw or some sort of backlashing occurring but I don't see an easy way to pull apart the Press to inspect the screw.  Has anyone experienced this issue or managed to find an easy way to expose the z-axis screw?

Re: Z-Axis issue

Can you manually raise the front of the bed?

What do you mean?  It's not possible to manually level the bed if that's what you mean.

Re: Z-Axis issue

Did you solve this?

I have a similar issue.  The bed bounces up and down when lowering through certain areas.  If I press gently upward on the front of the bed, the bouncing stops.

Rather annoying, as it causes bad alignment and missed gaps during a print.

Re: Z-Axis issue

This is a backlash issue on the Z-Axis, the only way to solve it seems to be with an anti-backlash mechanism of some sort.

Here's a link to my manual bed leveling thread where we discussed this.
