Re: X axis does not raise between auto leveling points

Hi dark_man

did get the problem solved because I have exactly the same and I m getting mad!!!!

Would be amazing if you could share your experience.

Re: X axis does not raise between auto leveling points

MindRealm — Tue, 13 Sep 2016 12:50:46 -0400

I assume you mean that the Z-axis doesn't raise (the X-axis is left-right, not up-down)

Looks like the setting is here:

// Probe Raise options provide clearance for the probe to deploy, stow, and travel.
//
#define Z_PROBE_DEPLOY_HEIGHT 15 // Raise to make room for the probe to deploy / stow
#define Z_PROBE_TRAVEL_HEIGHT 5  // Raise between probing points.

Per Line 544 in Configuration.h

Hope this helps!

X axis does not raise between auto leveling points

Hello,

I updated my Marlin firmware to Marlin-1.1.0-RC7. For auto bet leveling I'm using a fixed probe, which is connected to pin 32 (former Z axis max). The z endstop is also used and is connected to pin 30.

The most important parts of my config file are shown below:

When I enter G28 all axis are homed and everything is fine. But G29 looks strange. First the Z axis is raised to the defined config position. Then X and Y are moved and the Z axis is tested by decreasing the size between probe and bed. Then the probe is not raised and moved to another position by changing X or Y. After arrival the printer recognize the probe endstop is hit and it moves directly to another position. Until all probe points are done. Lastly the Z_PROBE_END_SCRIPT is started.

Before I updated to RC7 it looks completely different. After the first test the Z axis where raised again and deceased slowly. Then the Z axis raised again. X and Y where changed and the same procedure starts from the beginning.

I was already going through the recommendations from [github.com] but nothing changed.

Here you can see my log output. The first do_probe_raise(30) works fine, but the remaining do_probe_raise(25) have no effect. The Z axis does not move.
