M558 H Little monster Delta

The result of your heightmap looks very good. What is the problem you are actually having? Is your first layer printing ok?

Hello,

Yes it's my first layer that is 0.3mm. I am looking to go down to 0.2mm but G31 Z seems to change nothing.

Once again if you do G1 Z0 where does the tip of the nozzle end up in relation to the bed surface?

Thanks.

There is 0.3 between the nozzle and the bed

Just to be sure - this is after doing G1 Z0?

If that IS TRUE then edit config.g - find the M665 command - edit the value of the H parameter by adding 0.3 to it.

See if that doesn't solve your problem.

Keep in mind the config_override.g, so editing config.g might not show any difference

Right - I forgot that - I don't use config_override.g and it slipped my mind.

Thanks for the catch.

I'll have to rest. it took me simply mounted to 0.9mm to have a first layer of 0.16mm

Thanks again to those who took the time to read my bullshit.

Explain please. I do not understand what you have posted.

I changed G31 Z0.8 to G31 Z0.9 and after this change my 1st layer is fine

G31 Z0.8 = 1st layer to 0.3 (approximately)
G31 Z0.9 = 1st layer at 0.16

I will calibrate all of them later with a dial indicator

I do understand basic French, perhaps it would be easier to describe without having to translate?

RafB

oui super ca! J'ai fais beaucoup d'erreur car quand je faisais des modifications, je ne notais pas et il pouvais ce passer une journée avant de reprendre. Cette impression me semble propre. En PETG a 80mm/s avec un Bondtech ca marche bien pour l'instant. Je vais avoir tout une série de question par la suite.

Merci beaucoup pour ton acharnement à m'aider et essayé de comprendre mes erreurs de frappe.

Phaedrux

@rafb alright, I mostly understood that. My French has grown poor from disuse. Try to use simple phrase, so I can follow along. I won't be able to reply in French very well, so hopefully you can understand me in return.

Bon chance. Alonzi.

Well that is one way to do it as long as you do a probe every time the printer is turned on or the firmware reset or the printer is homed (I think need to test that).

I prefer to set the H parameter in M665 accurately so probing is not needed.

My probe is on a dedicated effector plate and it would be a bit of a pain to have to install it just to keep resetting the Z reference as needed.

To each their own. Glad to hear you got it working to your satisfaction.
