Manual level with a z probe

joehsmash

I want to manually mesh level my bed ignoring my z probe cuz its a piece of junk.

How can i do this? I dont have leveling screws so I can't use the assistant.

Set the Z probe type to 0 via M558, probe the bed, and restore the prior Z probe configuration. To dio this, change your bed.g to something like

M558 P0 ; turn off Z probe
G29 S0 ; probe the bed
M558 P1 ; provided P1 is in your config.g too

Make sure to put a M557 code with the correct mesh size in config.g before you run G32 / True Bed Levelling.

@chrishamm great i will try this, i didnt think to do that because the probe info is located in the config, and it has to be reloaded everytime i change something!

Ill try in the am!

Hi,

I have a file called configprobe.g that, as you might expect, configures my Z probe.

I call this file using M98 as needed.

Having a file like this means it can be called from another .g file, or a macro, etc.

@chrishamm just added to my bed.g file it brings up the adjustment screen but lets say i adjust the nozzle down 5mm the button just sits there and hangs, and will not let me go any lower, actually any button i press it does the same thing, just hangs.

just has the a ever ending refreshing circle on it.

May I ask what firmware and DWC version you're using?

@joehsmash said in Manual level with a z probe:

Duet Web Control 2.0.0-RC3

I suggest you update to at least DWC 2.0.7 for fw 2.05.1

Your wifi server is out of date as well by the way.

@Phaedrux YASSSSSSSSS

that totally fixed it.

the manual level fixed all the issues... now to get to perfecting my first layer again!

instead of the bed being off by a whopping 1.5m its only a 0.250 deviation off of a 0.2 thickness feeler!

loving it!

how do i mark as solved?
