Cant get my nozzle close to bed at all when trying to print

Fixed that but now it says insufficient axis's homed How can i stop this from happening becuase it say i need to home x and y first before homing z but i can home x because it says
G28 X
Error: G0/G1: insufficient axes homed

[whosrdaddy]

Reading the firmware upgrade notes would have prevented this question
In recent firmwares you cannot move axes before they are homed, so you must add S2 to G1 moves for non homed axes...
Anyway, you can add M564 H0 to your config.g file to have the old behavior back...

Still not using the mesh bed compensation during print. Even after i updated. Any idea why?

[Phaedrux]

@puppet172 Did you add the M375 or G29 S1 command to load the height map to your config.g?

[Puppet172]

@phaedrux
no where would i add that
0_1530485751276_config (3).g

[Phaedrux]

Just add M375 anywhere in config.g.

I put mine in the section where I configure the mesh size and z probe.

[Puppet172]

@phaedrux
That should fix it then?

[Phaedrux]

That will load the height map if you've run a successful compensation probing. That will adjust the nozzle height based on the probe data to keep it at the specified height from the bed at all times.

Hopefully that will resolve your issue.

@phaedrux
if i change me trigger height should i run another mesh bed compensation( G29)

[Phaedrux]

I'm not sure about that. As long as the probe is triggering consistently when you make the map the new trigger height should be applied after homing z and it should follow the height map correctly, but I could be wrong in my thinking there.

Regardless, I like to follow this order for bed leveling just to make sure.

Mechanically level your bed as well as you can first.

Measure your trigger height at least 10 times and take the average (or mode if it looks like a single value repeats most often).

Then run a compensation probing routine knowing that the results should be as accurate as possible.

Then you can varify that the height compensation is applied by moving to z=0.5 and jogging the head over the bed and see if the z axis is engaging to keep the distance the same as it moves.

@phaedrux @dc42

When im doing a mesh bed compensation It keeps getting to a point where the bed is a little higher there and it triggers the probe before it probes there. so i get this
Error: Z probe already triggered before probing move started
Is there anyway to get around this because all my axis's are level the bed just isnt
Thanks

You can try increasing your dive height a millimeter or two.

[Puppet172]

@phaedrux
Where is that?

[Puppet172]

@puppet172 @Phaedrux
Nvm found it

[Phaedrux]

The H value in the M558 command in config.g

[Phaedrux]

@puppet172 did it work?

[Puppet172]

@phaedrux @dc42
Yeah it worked.
And another question. When i re did my G29 to have more points to be more accurate, now when ever i print it is much higher off the print bed like a couple millimeters. Why would this be happening?
Thanks

@Phaedrux @dc42

I don't think the bed level is working to well
