BL Touch Issues... Again and Again...

DIY-O-Sphere

@fcwilt is one of the experienced users who really knows this stuff and spends a lot of time helping. But to help he must first understand what the problem is.
I can not get such an attitude ...

Edit:
Yes and sometimes he is also very accurate about terms. But that is certainly not to bother...

Can you describe what you are doing to probe the shape of the bed? Sometimes there are simple errors in probing that can cause issues and it would be good to know you are doing everything the right way.
Can you post a screenshot of your heightmap after probing? Sometimes that helps see something strange going on.
Can you post your config.g?
Can you describe in a little more detail what problem you are having? It sounds like if you go to Z=0 on the left-side of the bed that the nozzle is very close to the bed, and if you move to the right in the X axis and go to Z=0 that the nozzle is 1mm off the bed. Is that right?
Can you tell us what kind of printer you have?
Can you tell us what version of firmware you have?
Can you tell us what specific Duet board(s) you are using?

All those things help you get a quick correct set of things you can do to work towards getting better prints.

I can a spot a wind up when I see one. OP joined 28th at 17:30 then spent the next hour and half insulting anyone who tried to help. If this is such a big recurring problem, with multiple duet boards, how come we haven't seen any posts apart from this single thread?

What is a "wind up"?

I'm not familiar with that phrase.

Thanks.

That is very difficult to explain to a non- native English speaker. A wind up can mean many things but In this context, the best explanation I can give is - to say or do something with the deliberate and sole purpose of annoying or angering other people.

That sounds spot on.

Thanks for the explanation.

@kwad3d-0 post your config.g and response to M115, please. And what layout the printer is, eg Cartesian bedslinger, CoreXY, etc. I’d expect the probe is offset in Y axis, and your X carriage rotates around the x axis as it goes from one end to the other, causing probe to lift or drop relative to the nozzle.

Thanks for responding. Its a Core XY machine. The leveling performs just fine besides being off on one side consistently. I can see the Z motors adjusting as it progresses across the bed. The amount of lift is consistent enough that all I have to do after finishing a probe is reach down and clock the one Z motor one click and the desired affect is achieved. There may be a simpler solution as the only reason I have to re level is due to the bed being heavier then normal and drooping when the motors go to idle. So is it possible to simply adjust the idle current to provide more support to the bed between prints? Then the minor inconvenience of manually adjusting the one Z axis would only have to be done after the printer is shut down... which is only like once a month.

@kwad3d-0 please, config.g, response to M115, and ideally the macro you’re running for bed levelling. Without these a useful answer is all but impossible. See points mentioned here https://forum.duet3d.com/post/53522

@droftarts Ok I will provide that info soon as I get back to the Office. Regardless I would like to increase the idle strength of the motors to prevent the bed droop between prints. Is that possible?

Yes, it's possible.

Check the "I" parameter in your M906 configuration command.

If you post your config.g many of us can help you with that question.

@alankilian
Normally the deactivation of the motors will happen via the endcode of the slicer....

Oh MAN, that's certainly a possibility.

I forgot I removed that from my Simplify3D profile.

Good catch. This is why we're all here.

@Kwad3D-0 You should also post a small but complete GCODE file so we can see the start and stop codes.

just a dumb question @Kwad3D-0
before you create your mesh bed do you perform only a Zhome or do you perform a G32 (if you confiogured your bed.g to perform a dual (or triple ? ) z bed levelling.
and do you also perform a G32 before you print ? (and of course both wioth the bed at print temp)

personnaly i know that without a G32 i may have shifting in Zaxis cause of my left motor.
This is the only way to be sure that the reference is always the same.
and of course i cancel the mesh bed levelling at the beginning of the bed.g

and as severall people asked: can you provide your config.g, bed.g and the gcode you use to create your meshbed and the one you use when you start to print something.

this way people will be able to helps you. thanks

@arnold_r_clark honnestly i'm sorry to says that but @Kwad3D-0 wasn't cool at all, because for me too his sentence was not clear at all and could mean severall things. and instead of trying to rephrase he just choose to attack the guy that tried to helps him because HE knows.... but if HE knows better what's he's talking about why do he asks the question ??

when you asks for help it's sometimes VERY VERY usefull to just rephrase to explain to someone else that tries to helps you because it can either help the other people to know exactly what you are saying ( and not everyone is english native langage don't forget that) either it can simply makes you thing another way and see the things differently and find yourself a solution to your problem.

but honnestly if a guy gives me this answer:
"If I have to explain what that meant then you obviously are not going to be of much assistance"
i jsut want to answer him ok then go f*** yourself and don't waste our time.

and yes his sentence is crappy, the real one should be "the mesh generated got values that doesn't match the real position of the bed on the left (or right), they are offseted"

this sentence isn't ambiguous at all.
but he knows better and while people asked him (including @jay_s_uk who i think knows FAR FAR FAR better than him everything on how it works) to post his configuration, 5 days later he didn't.

but honnestly after looking this thread more deeply i jsut regret my post just above where i try to helps him because he's just toxic. jays reaction was the good one leave him with his problem as he don't really want an answer but just tell that RRF is crappy and makes him loosing money.

As a Teacher I understand frustration when i see it .

As a person I see patronizing when I see it.

@zapta yeah his question is jsut an order, not even a thanks.
and wow a reputation of -11... didn't thought it was possible.

If you look hard, you will find another kwad3d profile.

@paulhew yeah i thought he was toxic the second i saw there was two kwad3d
on the BLV FB page we had a same kind of guy complaining that he got a farm and things annoys him, and when we tried to explain to him he started be toxic. we explained him his behavior wasn't allowed and he quit the group of course not without telling we were just dumb guys that just play with toys while HE works. maybe he's the same guy
