M558 H Little monster Delta

@phaedrux said in M558 H Little monster Delta:
@RafB If 0.7 versus 0.8 is not enough of a difference, perhaps try using baby stepping to make adjustments until your first layer is good, and then take the baby stepping and add or subtract it to your G31 Z height value to make the change permanent.
What does that value have to do with setting Z=0 to be just touching the bed?
I always obtain that condition by adjusting the H parameter in M665 for my deltas.

@fcwilt well it's not really clear if he's talking about M558 H or G31 Z. I'm assuming he means the trigger height of his probe affecting his first layer. But I could be wrong.
-
Another mistake on my part. I can not remember this code!
So actually it's not M558 but G31
I am french and the translation by google of the clibration of a delta printer is not clear. I know I would have to work at school to better understand English.
So when I change G31 Z + or- my print still has the 1st layer at 0.3mm

Well I may be doing it wrong but I have always adjusted the distance from nozzle to bed at Z=0 by setting the H parameter in M665 (for delta printers course).
The only thing I have been able to determine about the Z setting in G31 is that it affects the generation of the heightmap.csv file.
I find the documentation about G31 to be a little confusing in some areas.

Do you mean the display still shows 0.3? or you think it's still printing too high?
Can you make further adjustment with baby stepping?Have you measured what the trigger height should be?

Hello,
Yes I followed all the procedures but rather this tutorial
https://www.youtube.com/watch?v=BgkJVgFnPaEI hope that it is not the bltouch V2 which poses problem?
I just redo the procedure and I find 0.7mm
Well I will try to mount 100micron per 100micron to know if G31 Z works.
And reread

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

@rafb said in M558 H Little monster Delta:

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 0.16I 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?
-
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.
-
@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.
